# Trips

Mode: RFC‑S

Trip 0 (10.020) to Trip 9 (10.029) store the most recent 10 trips that have occurred where Trip 0 (10.020) is the most recent and Trip 9 (10.029) is the oldest. When a new trip occurs it is written to Trip 0 (10.020) and all the other trips move down the log, with oldest being lost. The date and time when each trip occurs are also stored in the date and time log, i.e. Trip 0 Date (10.041) to Trip 9 Time (10.060). The date and time are taken from Date (06.016) and Time (06.017). Some trips have sub-trip numbers which give more detail about the reason for the trip. If a trip has a sub-trip number its value is stored in the sub-trip log, i.e. Trip 0 Sub-trip Number (10.070) to Trip 9 Sub-trip Number (10.079). If the trip does not have a sub-trip number then zero is stored in the sub-trip log.

Trip categories and priorities
Trips are grouped into the categories given in the table below. A trip can only occur when the drive is not tripped, or if it is already tripped and the new trip has a higher priority than the active trip (i.e. lower priority number). Unless otherwise stated a trip cannot be reset until 1.0s after it has been initiated.

Priority | Category | Trips | Comments
1 | Internal faults | HF01 - HF28 | These are fatal problems that cannot be reset. All drive features are inactive after any of these trips occur. These trips are not stored in the trip log.
1 | Stored HF trip | Stored HF | This trip cannot be cleared unless 1299 is entered into Parameter mm.000 (mm.000) and a reset is initiated.
2 | Non-resettable trips | Trip numbers 218 to 247, Slot1 HF, Slot2 HF, Slot3 HF or Slot4 HF | These trips cannot be reset.
3 | Volatile memory failure | EEPROM Fail | This can only be reset if Parameter mm.000 (mm.000) is set to 1233 or 1244, or if Load Defaults (11.043) is set to a non-zero value.
4 | Internal 24V power supply | PSU 24V |
5 | Non-volatile media trips | Trip numbers 174, 175 and 177 to 188 | These trips are priority 6 during power-up.
5 | Position feedback interface power supply | Encoder 1 | This trip can override Encoder 2 to Encoder 6 trips.
6 | Trips with extended reset times | OI ac, OI Brake, and OI dc | These trips cannot be reset until 10s after the trip was initiated.
6 | Phase loss and d.c. link power circuit protection | Phase Loss and OHt dc bus | The drive will attempt to stop the motor before tripping if a Phase Loss.000 trip occurs unless this feature has been disabled (see Action On Trip Detection (10.037). The drive will always attempt to stop the motor before tripping if an OHt dc bus occurs.
6 | Standard trips | All other trips |

Internal faults
Trips {HF01} to {HF28} are internal faults that do not have trip numbers. If one of these trips occurs, the main drive processor has detected an irrecoverable error. All drive functions are stopped and the trip message will be displayed on the drive keypad. The error can only be reset by powering the drive down and up again. The table below gives the reasons for internal faults and their corresponding trip.

Trip | Reason
{HF01} | CPU hard fault.
{HF02} | CPU memory management error.
{HF03} | CPU bus fault.
{HF04} | CPU usage fault.
{HF05} | An interrupt has occurred that does not have a defined function.
{HF06} | Before version 0X.40.00.00: An interrupt has occurred which is reserved. Version 0X.40.00.00 and later: A supply transient has been caused on the control board (usually because an option module has been hot plugged). Sub-trip 1 indicates this has been detected in the 4ms task. Sub-trip 2 indicates the transient caused data to be misread over a processor bus and caused a bus or usage fault.
{HF07} | Watchdog failure
{HF08} | CPU Interrupt crash
{HF09} | Free store overflow
{HF10} | Not used
{HF11} | Non-volatile memory comms error
{HF12} | Stack overflow. Sub-trip is shown to indicate which stack: 1 - Interrupt task 2 - Background task 3 - Derivative freewheeling task 4 - Derivative timed task 5 - User program freewheeling task 6 - User program timed task
{HF13} | The control hardware is not compatible with the firmware. The sub-trip number gives the actual ID code of the control board hardware.
{HF14} | CPU register bank error (<V01.40.00.00 only).
{HF15} | CPU divide error (<V01.40.00.00 only).
{HF16} | RTOS error (the background task has returned)
{HF17} | The clock supplied to the control board logic is out of specification
{HF18} | The internal flash memory has failed when writing option module parameter data. Sub-trip is shown to indicate which failure: 1 - Programming error while writing menu in flash 2 - Erase flash block containing setup menus failed 3 - Erase flash block containing application menus failed (<V01.40.00.00 only).
{HF19} | Invalid main application firmware CRC. Reprogramming required.
{HF20} | The ASIC is not compatible with the firmware. The sub-trip number displayed is the ASIC version.
{HF23} | If this trip occurs please consult the drive supplier.
{HF24} | If this trip occurs please consult the drive supplier.
{HF25} | If this trip occurs please consult the drive supplier.
{HF26} | The control pod is either a UF90A or a UF99A and is fitted to a power stage that is not compatible because it only provided two phase current feedback. If this trip occurs please consult the drive supplier.
{HF27} | The internal factory fit I/O module is not compatible with the control board or is not present. The sub-trip shows the hardware identifier given by the module.
{HF28} | The internal factory fit position feedback module is not compatible with the control, board. The sub-trip shows the hardware identifier given by the module.

When the drive is subsequently powered up a Stored HF trip is initiated where the sub-trip number is the number of the HF trip that last occurred. This trip will occur at every power-up until it is reset. The trip can only be reset by first entering 1299 into Parameter mm.000 (mm.000). If the drive is powered up and a Stored HF trip occurs, Onboard User Program: Enable (11.047) is reset to zero to prevent the on-board user program from running. This ensures that the user program can be changed or erased in case it causes an HF trip at every power-up. Once the Stored HF is cleared, it is necessary to power cycle the drive or to re-download the user program to allow the program to restart.

Braking IGBT
The list below gives conditions that will disable the braking IGBT:

1. Braking IGBT Upper Threshold (06.074) = 0, or Low Voltage Braking IGBT Threshold Select (06.076) = 1 and Low Voltage Braking IGBT Threshold (06.075) = 0.
2. The drive is in the under-voltage state.
3. A priority 1, 2 or 3 trip is active (see Trip 0 (10.020)).
4. One of the following trips is active or would be active if another trip is not already active: OI Brake, PSU, Th Brake Res or OHt Inverter.
5. Percentage Of Drive Thermal Trip Level (07.036) = 100%. This is an indication that some part of the drive is too hot and is used to indicate if an internally fitted braking resistor is too hot.
6. Brake R Too Hot is active or the system has been set up to disable the braking IGBT based on the braking resistor temperature and the resistor is too hot (i.e. bit 2 of Action On Trip Detection (10.037) is set).

Note that the braking IGBT over-current trip cannot be reset until 10s after it is initiated. This period consists of a 9s period after the trip where the braking IGBT cannot be switched on again and the OI Brake trip is held active and cannot be reset. This 9s period is followed by the normal 1s delay, that is present for other trips, before the trip can be reset. During this 1s period it is possible for the braking IGBT to switch on again. If the conditions are still present that caused the trip then the trip will be initiated again with a further 9s hold-off period etc.

Trips (alphabetical order)

Trip | Active Rectifier
--- | ---
Value | 95
Short description | The active input rectifier has tripped.

Normally active input rectifier trips give similar trips to the output converter that controls the motor with a suitable sub-trip code to indicate that the trip has been initiated by the rectifier. However it is possible for a fault in the active input rectifier control board to cause other trips that are not intercepted by the main control board. These are indicated by this trip with a sub-trip code that indicates the reason for the trip. The sub-trip code value corresponds to the trips defined by Trip 0 (10.020).

Trip | An Input 1 Loss
--- | ---
Value | 28
Short description | Analog input 1 current loss

Indicates that a current loss was detected in current mode on Analog Input 1 (Terminal 5, 6). In 4-20mA and 20-4mA modes. loss of input is detected if the current falls below 3mA. See Analog Input 1 Mode (07.007) for further details.

Recommended actions:

- Check control wiring is correct.
- Check control wiring is undamaged.
- Check Analog Input 1 Mode (07.007).
- Check that the current signal is present and greater than 3mA.

Trip | An Input 2 Loss
--- | ---
Value | 29
Short description | Analog input 2 current loss

Indicates that a current loss was detected in current mode on Analog Input 2 (Terminal 7). In 4-20mA and 20-4mA modes. loss of input is detected if the current falls below 3mA. See Analog Input 2 Mode (07.011) for further details.

Recommended actions:

- Check control wiring is correct.
- Check control wiring is undamaged.
- Check Analog Input 2 Mode (07.011).
- Check that the current signal is present and greater than 3mA.

Trip | An Output Calib
--- | ---
Value | 219
Short description | Analog output calibration failed

The zero offset calibration of one or both of the analogue outputs has failed. This indicates that the drive hardware has failed, or a voltage has been applied to the output via a low impedance possibly due to a wiring error.

Sub-trip | Reason
1 | Output 1 failed
2 | Output 2 failed

Recommended actions:

- Check the wiring associated with analog outputs.
- Remove all the wiring that is connected to analog outputs and perform a recalibration by power cycling the drive.
- If trip persists, replace the drive.

Trip | App Menu Changed
--- | ---
Value | 217
Short description | Customisation table for an application menu has changed

The customisation table for an application menu has been changed. The sub-trip indicates which menu has changed:

Sub-trip | Reason
1 | Menu 18
2 | Menu 19
3 | Menu 20

If more than one menu has changed the lowest menu has priority. Drive user parameters must be saved to prevent this trip on the next power-up.

Recommended actions:

- Reset the trip and perform a parameter save to accept the new settings.

Trip | Autotune 1
--- | ---
Value | 11
Short description | Position feedback did not change or required speed could not be reached during an autotune

The drive has tripped during an auto-tune. The cause of the trip can be identified from the sub-trip number.

Sub-trip | Reason | Recommended actions
1 | The position feedback did not change when position feedback is being used during rotating auto-tune. | Ensure that the motor is free to turn (i.e. mechanical brake is released). Check that the position feedback is selected correctly and operates correctly.
2 | The motor did not reach the required speed during mechanical load measurement. | Ensure that the motor is free to turn and that the static load plus inertia is not too large for the drive to accelerate within the test time.
3 | The required commutation signal edge could not be found during a rotating auto-tune with a Commutation Only position feedback device. | Check that the position feedback signals are connected correctly.
4 | The required movement angle cannot be produced during a minimal movement test. | Reduce the angular movement required.
6 | The phasing offset angle is measured twice during a stationary auto-tune and the results are not within 30o of each other. | If a minimal movement test is being used and excessive motor movement is occurring during the test reduce the required angle movement. Otherwise try and increase the required angle movement.
7 | The motor is moving when a phasing test on enable is selected and the drive is enabled, but the motor is still moving at a speed above the zero speed threshold. | Ensure that the motor is stationary before the drive is enabled.
9 | During the final stage of the minimal movement phasing test with a constrained motor it was not possible to achieve the required movement. | Reduce the angular movement required.

Trip | Autotune 2
--- | ---
Value | 12
Short description | Position feedback direction incorrect during an autotune

The drive has tripped during a rotating auto-tune. The cause of the trip can be identified from the associated sub-trip number.

Sub-trip | Reason | Recommended actions
1 | The position feedback direction is incorrect when position feedback is being used during a rotating auto-tune. | Check motor cable wiring is correct. Check feedback device wiring is correct. Swap any two motor phases to reverse the motor direction. Set either P1 Feedback Reverse (03.056) or Reverse Output Phase Sequence (05.042) to invert the feedback or output phase rotation from the drive.
2 | A SINCOS encoder with comms is being used for position feedback and the comms position is rotating in the opposite direction to the sine wave based position. | Check feedback device wiring is correct.

Trip | Autotune 3
--- | ---
Value | 13
Short description | Measured inertia has exceeded the parameter range or commutation signals changed in wrong direction during an autotune

The drive has tripped during a rotating auto-tune or mechanical load measurement. The cause of the trip can be identified from the associated sub-trip number.

Sub-trip | Reason | Recommended actions
1 | Measured inertia has exceeded the parameter range during a mechanical load measurement. |
2 | The commutation signals changed in the wrong direction during a rotating auto-tune. | Check motor cable wiring is correct. Check feedback device U, V and W commutation signal wiring is correct.
3 | The mechanical load test has been unable to identify the motor inertia. | Increase the test level. If the test was carried out at standstill repeat the test with the motor rotating within the recommended speed range.

Trip | Autotune 4
--- | ---
Value | 14
Short description | Drive encoder U commutation signal fail during an autotune

A position feedback device with commutation signals is being used (i.e. AB Servo, FD Servo, FR Servo, SC Servo or Commutation Only encoder) and the U commutation signal did not change during a rotating auto-tune.

Recommended actions:

- Check feedback device U commutation signal wiring is correct (Encoder terminals 7 and 8).

Trip | Autotune 5
--- | ---
Value | 15
Short description | Drive encoder V commutation signal fail during an autotune

A position feedback device with commutation signals is being used (i.e. AB Servo, FD Servo, FR Servo, SC Servo or Commutation Only encoder) and the V commutation signal did not change during a rotating auto-tune.

Recommended actions:

- Check feedback device V commutation signal wiring is correct (Encoder terminals 9 and 10).

Trip | Autotune 6
--- | ---
Value | 16
Short description | Drive encoder W commutation signal fail during an autotune

A position feedback device with commutation signals is being used (i.e. AB Servo, FD Servo, FR Servo, SC Servo or Commutation Only encoder) and the W commutation signal did not change during a rotating auto-tune.

Recommended actions:

- Check feedback device W commutation signal wiring is correct (Encoder terminals 11 and 12).

Trip | Autotune 7
--- | ---
Value | 17
Short description | Motor number of poles / position feedback resolution set incorrectly

An Autotune 7 trip is initiated during a rotating auto-tune, if the number of motor poles or the position feedback resolution have been set up incorrectly where position feedback is being used. This trip will not occur if Number Of Motor Poles (05.011) = 6 (i.e. 12 poles).

Recommended actions:

- Check the lines per revolution for the feedback device.
- Check the number of poles in Number Of Motor Poles (05.011).

Trip | Autotune Stopped
--- | ---
Value | 18
Short description | Autotune test was stopped before completion

The drive was prevented from completing an auto-tune, because either the Final drive enable or the Final drive run were removed.

Recommended actions:

- Check the drive enable signal (Terminal 31) was active during the auto-tune.
- Check the run command was active in Digital Input 05 State (08.005) during the auto-tune.

Trip | Brake R Too Hot
--- | ---
Value | 19
Short description | Braking resistor thermal protection overload timed out

This trip indicates that braking resistor overload has timed out. The value in Braking Resistor Thermal Accumulator (10.039) is calculated using Braking Resistor Rated Power (10.030), Braking Resistor Thermal Time Constant (10.031) and Braking Resistor Resistance (10.061). This trip is initiated when Braking Resistor Thermal Accumulator (10.039) reaches 100%.

Recommended actions:

- Ensure the values entered in Braking Resistor Rated Power (10.030), Braking Resistor Thermal Time Constant (10.031) and Braking Resistor Resistance (10.061) are correct.
- If an external thermal protection device is being used and the braking resistor software overload protection is not required, set Braking Resistor Rated Power (10.030), Braking Resistor Thermal Time Constant (10.031) and Braking Resistor Resistance (10.061) to 0 to disable the trip.

Trip | CAM
--- | ---
Value | 99
Short description | Advanced motion controller cam failure

Advanced motion controller cam failure.

Sub-trip | Reason
1 | AMC Cam Start Index (35.001) > AMC Cam Size (35.003) or AMC Cam Start Position In Segment (35.002) > Cam Table In for the start index
2 | AMC Cam Index (35.007) has changed by more than 2 in one sample
3 | The rate of change at a segment boundary has exceeded the maximum value
4 | The sum of the AMC Cam Position In Segment (35.008) and the change of master position has exceeded the maximum value

Recommended actions:

- Check the cam setup parameters in menu 35 and cam table parameters in menu 36.

Trip | Card Busy
--- | ---
Value | 178
Short description | NV media card cannot be accessed as it is being accessed by an option module

The NV media card is already being accessed via comms, or by an option module, or a file cannot be opened on the drive (i.e. /par/diff file) because the file is already opened via comms.

Recommended actions:

- Attempt the card action again after any comms or option module access to the card has finished.

Trip | Card Data Exists

Value | 179
Short description | NV media card file already contains data

An attempt is being made to write to a file that already exists.

Recommended actions:

- Attempt to write to a different file on the card.
- Erase the file on the card using parameter mm.000 = 7yyy and a drive reset, and then attempt writing to the file again.
- If writing a parameter file to the card, overwrite the existing file on the card using parameter mm.000 = 3yyy and a drive reset.

Trip | Card Derivative
--- | ---
Value | 188
Short description | Derivative different between the source drive parameter file on the NV media card and the destination drive

A parameter difference file is being written to the drive, but the value of Drive Derivative (11.028) in the file header is different to the value in the drive. Parameters will be transfered to the target drive but some parameters in the destination drive may have different defaults or ranges, and some parameter may not exist.

Recommended actions:

- Ensure that the target drive is of the correct model and type.
- Ensure that the correct card file has been read from the card.

Trip | Card File Error
--- | ---
Value | 185
Short description | NV media card header file is incorrect

The information in the card header (or File /000 in the MCDF folder on an SD card) is out of range. This error can also occur when the file is from a SMART card if the internal file system header information is incorrect (i.e. file type).

Recommended actions:

- Erase/format the card using parameter mm.000 = 9999 and a drive reason. Beware that this will erase all drive related data from the card.

Trip | Card Full
--- | ---
Value | 184
Short description | NV media card is full

An attempt has been made to write more data, but the card is full.

Recommended actions:

- Erase unwanted files from the card using parameter mm.000 = 7yyy and a drive reset.
- Erase the whole card using parameter mm.000 = 9999 and a drive reset.
- Use a new blank card.

Trip | Card No Data
--- | ---
Value | 183

An attempt has been made to read a file that is not present on the card.

Recommended actions:

- Ensure that the correct file on the card is being read.

Trip | Card Option
--- | ---
Value | 180
Short description | Option modules installed are different between source drive data on the NV media card and destination drive

A parameter file has been transferred from a NV media card to the drive, but at least one of the option modules are different between source and target drives. This trip does not stop the data transfer but is a warning that the data for the option modules that are different will be set to default values and not the values from the card.

Recommended actions:

- Ensure that the correct option modules are fitted to the target drive.
- Ensure that the correct card file has been read from the card.

Trip | Card Product
--- | ---
Value | 175
Short description | NV media card is from another product and is not compatible

The NV media card is from another product and is not compatible.

Trip | Card Rating
--- | ---
Value | 186
Short description | Voltage rating different between the source drive parameter file on the NV media card and the destination drive

A parameter difference file is being written to the drive, but the value of Drive Rated Voltage (11.033) in the file header is different to the value in the drive. Parameters other than those that a rating dependent (i.e. have the RA attribute) will be transferred to the drive although their values maybe limited to be within the range supported by the target drive. Rating dependent parameters will be set to their default value.

Recommended actions:

- Ensure that the target drive is of the correct voltage rating.
- Ensure that the correct card file has been read from the card.

Trip | Card Read Only
--- | ---
Value | 181
Short description | NV media card is read-only

An attempt is being made to write to a read-only card or file.

Recommended actions:

- Ensure that the read-only flag on the card is not set by using parameter mm.000 = 9777 and resetting the drive.

Trip | Card Slot
--- | ---
Value | 174
Short description | Communications issue between the drive and option module during an NV media card action

A failure has occurred in the communications between the drive and an option module when reading or writing data. The sub-trip indicates the option slot.

Recommended actions:

- Attempt the card action again.
- Ensure the option module has the latest firmware version.
- Consider replacing the option module.

Trip | Card User Prog
--- | ---
Value | 177
Short description | Onboard user program is write-only or does not exist, and cannot be transferred to an NV media card

An attempt has been made to transfer an onboard user program from the drive to the card but this is not possible due to one of the following reasons.

- The onboard user program is write-only (user program intellectual property protection has been enabled) which prevents the user program from being read from the drive.
- There is no user program present in the drive.

Trip | Cloning
--- | ---
Value | 102
Short description | Failure of the cloning function

If an attempt is made to use the cloning system to back-up the drive and option modules (parameter mm.000 values from 40001 to 40999) or restore the drive and option modules (parameter mm.000 values from 60001 to 60999) and the action fails then a "Cloning" trip is initiated. The sub-trip value indicates the reason for the trip.

Sub-trip | Reason
1 | The option module in Slot 1 has indicated that it will either back-up or restore its data to/from an SD card, but has failed to respond correctly and the system has timed out.
2 | As 1, but for Option Slot 2.
3 | As 1, but for Option Slot 3.
4 | As 1, but for Option Slot 4.
5 | Back-up folders exist or cannot be created when a back-up is initiated.
6 | The required back-up folders do not exist when a restore is initiated.

Trip | Configuration
--- | ---
Value | 111
Short description | Number of power modules or rectifiers installed is different from the number expected

The Number Of Power Modules Detected (11.071) is different from the number expected. The sub-trip value indicates the number of power modules expected.

Recommended actions:

- Ensure that all the power modules are correctly connected and powered up.
- Ensure that the value in Number Of Power Modules Detected (11.071) is set to the number of power modules connected.
- Set Number Of Power Modules Test (11.035) to 0 to disable the trip if not required.

This trip is also initiated if the number of external rectifiers connected to each power module is less than the number defined by Number Of Rectifiers Expected (11.096). If this is the reason for the trip the sub-trip is 10x where x is the number of external rectifiers that should be connected.

Recommended actions:

- Ensure that all the external rectifiers are connected correctly.
- Ensure that the value in Number Of Rectifiers Expected (11.096) is correct.

Trip | Control Word
--- | ---
Value | 35
Short description | Trip initiated from the Control Word

This trip is initiated by setting bit 12 on the control word in Control Word (06.042) when the control word is enabled (Control Word Enable (06.043) = On).

Recommended actions:

- Check the value of Control Word (06.042).
- Disable the control word in Control Word Enable (06.043).

Trip | Current Offset
--- | ---
Value | 225
Short description | Current feedback offset error

The current feedback offset is too large to be trimmed correctly. The current feedback offset is always measured at power up before the drive is enabled. In motor control modes the current feedback offset is also measured whenever the drive is not active such that no current should be flowing in the output. In regen mode the current feedback offset is measured when the drive comes out of the under voltage state.

The sub-trip relates to the output phase for which the offset error has been detected.

Sub-trip | Reason
1 | U phase
2 | V phase
3 | W phase

Recommended actions:

- Ensure that there is no possibility of current flowing in the output phase of the drive when the drive is not enabled.
- If frame size 6 or larger is being used and a 24V backup supply is connected to terminals 1/2 of the control module, then ensure that a 24V supply is also connected to terminals 51/52 on the power stage.
- Hardware fault - contact the supplier of the drive.

Trip | Data Changing
--- | ---
Value | 97
Short description | Drive parameter data is changing and the drive has been commanded to enable

A user action or a file system write is active that is changing the drive parameters and the drive has become active, i.e. Drive Active (10.002) = 1. The user actions that change drive parameters are loading defaults, changing drive mode, or transferring data from an NV memory card or a position feedback device to the drive. The file system actions that will cause this trip to be initiated if the drive is enabled during the transfer are writing a parameter or macro file to the drive, or transferring a derivative or user program to the drive. It should be noted that none of these actions can be started if the drive is active, and so the trip only occurs if the action is started and then the drive is enabled.

Recommended actions:

- Ensure the drive is not enabled when one of the following is being carried out:

- Loading defaults
- Changing drive mode
- Transferring data from a NV media card or position feedback device
- Transferring user programs

Trip | Derivative ID
--- | ---
Value | 247
Short description | Derivative identification error

There is a problem with the identifier associated with derivative image which customises the drive. The reason for the trip is given by the sub-trip as follows.

Sub-trip | Reason

2 | The identifier is out of range.
3 | The derivative image has been changed.

Trip | Derivative Image
--- | ---
Value | 248
Short description | Derivative product image error

An error has been detected in the derivative product image. The sub-trip indicated the reason for the trip.

Sub-trip | Reason | Comments

4 | Attempted access to non-existent parameter |
5 | Attempted write to read-only parameter |
6 | Attempted and over-range write |
7 | Attempted read from write-only parameter |
30 | The image has failed because either its CRC is incorrect, or there are less than 6 bytes in the image or the image header version is less than 5. | Occurs when the drive powers-up or the image is programmed. The image tasks will not run.
31 | The image requires more RAM for heap and stack than can be provided by the drive. | As 30.
32 | The image requires an OS function call that is higher than the maximum allowed. | As 30.
40 | The timed task has not completed in time and has been suspended. | The image tasks will be disabled. A power-cycle of the drive will be needed to restart the image tasks.
41 | Undefined function called, i.e. a function in the host system vector table that has not been assigned. | As 40.
51 | Core menu customisation table CRC check failed | As 30.
52 | Customisable menu table CRC check failed | As 30.
53 | Customisable menu table changed | Occurs when the drive powers-up or the image is programmed and the table has changed. Defaults are loaded for the derivative menu and the trip will keep occurring until drive parameters are saved.
61 | The option module fitted in slot 1 is not allowed with the derivative image. | As 30.
62 | The option module fitted in slot 2 is not allowed with the derivative image. | As 30.
63 | The option module fitted in slot 3 is not allowed with the derivative image. | As 30.

80 | *Image is not compatible with the control board | Initiated from within the image code.
81 | *Image is not compatible with the control board serial number | As 80.

Recommended actions:

- Contact the supplier of the drive.

Trip | Destination
--- | ---
Value | 199
Short description | The destination of two or more functions are writing to the same parameter

This trip indicated that destination output parameters of two or more logic functions (Menus 05, 07, 08, 09, 12 or 14) within the drive are writing to the same parameter.

Recommended actions:

- Set Pr mm.000 to "Destinations" or 12001 and check all visible parameters in all menus for parameter write conflicts.

Trip | Drive Size
--- | ---
Value | 224
Short description | Unrecognized drive size/rating

This trip indicates that the control PCB has not recognized the drive size of the power circuit to which it is connected.

Recommended actions:

- Ensure the drive is programmed to the latest software version.
- Hardware fault - return drive to supplier.

Trip | EEPROM Fail
--- | ---
Value | 31
Short description | Non-volatile memory issue detected causing default parameter values to be loaded

EEPROM Fail trip indicates that default parameters have been loaded because of the reasons given below.

Sub-trip | Reason
1 | The most significant digit of the internal parameter database version number has changed.
2 | The CRC's applied to the parameter data stored in internal non-volatile memory indicate that a valid set of parameters cannot be loaded.
3 | The drive mode restored from internal non-volatile memory is outside the allowed range for the product or the derivative image does not allow the previous drive mode.
4 | The drive derivative image has been changed and it has changed the customisation of the drive core menus.
5 | The power stage hardware has been changed and it has changed the customisation of the drive core menus.
6 | The internal I/O hardware has been changed and it has changed the customisation of the drive core menus.
7 | The position feedback interface hardware has been changed and it has changed the customisation of the drive core menus.
8 | The control board hardware has been changed and it has changed the customisation of the drive core menus.
9 | The checksum on the non-parameter area of the EEPROM has failed.

The drive holds two banks of user save parameters and two banks of power down save parameters in non-volatile memory. If the last bank of either set of parameters that was saved is corrupted a User Save or Power Down Save trip is produced. If one of these trips occurs the parameters values that were last saved successfully are used. It can take some time to save parameters when requested by the user and if the power is removed from the drive during this process it is possible to corrupt the data in the non-volatile memory. The Power Down Save trip can occur if the d.c. bus is discharged too quickly after the supply has been removed, for example with the use of external discharge resistors.

If both banks of user save parameters or both banks of power down save parameters are corrupted or one of the other conditions given in the table above occurs an EEPROM Fail.2 trip is produced. If this trip occurs it is not possible to use the data that has been saved previously, and so the drive will be in lowest allowed drive mode with default parameters. The trip can only be reset if Parameter mm.000 (mm.000) is set to 10, 11, 1233 or 1244 or if Load Defaults (11.043) is set to a non-zero value.

Recommended actions:

- Default the drive and perform a drive reset.
- Allow sufficient time to perform a save before the supply to the drive is removed. Disconnect any external discharge resistors that maybe used to discharge the d.c. bus quickly after the supply has been removed.
- If the trip persists, return drive to the supplier.

Trip | Encoder 1
--- | ---
Value | 189
Short description | Drive position feedback interface power supply overload

Drive position feedback interface power supply overloaded. Terminals 13 & 14 of the 15 way D-type connector can supply a maximum current of 200mA at 15V or 300mA at 5V.

Recommended actions:

- Check encoder power supply wiring.
- Disable the termination resistors (P1 Termination Select (03.039) set to 0) to reduce current consumption.
- For 5V encoders with long cables, select 8V (P1 Supply Voltage (03.036)) and fit a 5V voltage regulator close to the encoder.
- Check the encoder specification to confirm it is compatible with the encoder port power supply current capability.
- Replace the encoder.
- Use an external power supply with higher current capability.

Trip | Encoder 2
--- | ---
Value | 190
Short description | Wire break between the drive and the position feedback device

There is a wire break between the drive and the position feedback device. These trips are provided for the P1 position feedback interface only and the exact cause of the trip can be identified from the sub-trip number as given below.

Sub-trip | Reason
1 | Resolver or SINCOS sine wave signals
11 | Digital incremental A signal
12 | Digital incremental B signal
13 | Digital incremental Z signal
14 | SC SC device single turn sine wave commutation signals.
15 | SC SC device marker

This trip can occur if the position feedback device type selected in P1 Device Type (03.038) is not correct for the position feedback device connected to the drive.

Recommended actions:

- Ensure that the position feedback device type selected in P1 Device Type (03.038) is correct for the position feedback device connected to the P1 interface on the drive.
- If wire break detection on the drive encoder input is not required, set bit 0 of P1 Error Detection Level (03.040) to 0 to disable the Encoder 2 trip.
- If the trip is due to the digital incremental Z (marker signal) this is often not connected. Check that this trip is disabled by setting P1 Termination Select (03.039) to a value that disables the termination on this input, which will disable hardware wire break detection.
- Check cable continuity.
- Check wiring of feedback signals is correct.
- Check encoder power supply is set correctly (P1 Supply Voltage (03.036)).
- Replace the encoder.
- If a Heidenhain ERN1387 encoder is being used the marker is a low level signal. Ensure that Bit 3 of P1 Error Detection Level (03.040) is set so that the drive is set up for this type of marker signal.
- The marker signal does not need to be used with SCSC type devices if it is not required to give more accurate absolute position. If this is the case it is important to disable the effect of the marker with Bit 4 of P1 Marker Mode (03.031) and to ensure that marker wire break detection is not enabled with Bit 6 of P1 Error Detection Level (03.040).

Trip | Encoder 3
--- | ---
Value | 191
Short description | Incorrect position feedback phase offset angle detected while running

The drive has detected an incorrect UVW phase angle while running (RFC-S mode only) or SINCOS phase error. The feedback device which has caused the trip can be identified by the sub-trip number.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Check encoder shield connections.
- Ensure the encoder cable is one uninterrupted cable.
- Check the encoder signal for noise with an oscilloscope.
- Check the integrity of the encoder mechanical mounting.
- For an encoder with UVW commutation signals (AB Servo, SC Servo, etc.), ensure that the phase rotation of the UVW commutation signals is the same as the phase rotation of the motor.
- For a SINCOS encoder, ensure that motor and incremental SINCOS connections are correct and that for forward rotation of the motor, the encoder rotates clockwise (when looking at the shaft of the encoder).
- Repeat the offset measurement test.
- If phase error detection is not required then set bit 1 of P1 Error Detection Level (03.040) to 0.

Trip | Encoder 4
--- | ---
Value | 192
Short description | Encoder communications has timed out

This trip indicates that the encoder communications has timed out or the communications position message transfer time is too long. This trip can also be caused due to a wire break in the communication channel between the drive and the encoder. The feedback device which has caused the trip can be identified by the sub-trip number.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Check the encoder wiring.
- Ensure the encoder power supply setting (P1 Supply Voltage (03.036)) is correct.
- If using an EnDat, BiSS or SSI encoder ensure that the DATA channel uses pins 1/2 and the clock uses pins 3/4. This is different to a SC EnDat, SC BiSS or SC SSI encoder which uses the DATA channel on pins 5/6 and clock on 11/12. Use the device types of EnDat Alt, SSI Alt or BiSS Alt if necessary.
- If using a BiSS encoder which only supports unidirectional data transfer then set P1 Auto-configuration Select (03.041) to Disabled (0) and configure the encoder manually.
- If using a BiSS encoder ensure that the encoder supports a baud rate of 100kbaud as the drive uses this baud rate for the line delay compensation test and will generate this trip if the encoder does not support 100kbaud.
- Replace the feedback device.

Trip | Encoder 5
--- | ---
Value | 193
Short description | Encoder communications checksum or CRC error

This trip indicates that there is a checksum or CRC error, or the SSI encoder is not ready. The Encoder 5 trip can also indicate a wire break to a communications based encoder.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Check the encoder cable shield connections.
- Ensure the cable is one uninterrupted cable - remove any connector blocks or if unavoidable minimise the length of any shield pigtails to the connector block.
- Check the encoder signal for noise with an oscilloscope.
- Check P1 Comms Bits (03.035).
- If using a Hiperface or EnDat encoder, carry out an encoder auto-configuration (P1 Auto-configuration Select (03.041) = Enabled).
- If using a BiSS or SC BiSS encoder then this trip could indicate that the encoder does not contain a BP3 EDS (BiSS Profile 3 Electronic Data Sheet). In this case ensure that the following parameters are set correctly: P1 Rotary Turns Bits (03.033), P1 Rotary Lines Per Revolution (03.034), P1 Comms Bits (03.035) and P1 Calculation Time (03.060).
- If using a BiSS encoder ensure the CRC is set correctly in P1 Additional Configuration (03.074). For most BiSS encoders P1 Additional Configuration (03.074) should be set to 67 000 000. If the encoder uses a different CRC then disable auto-configuration in P1 Auto-configuration Select (03.041) and configure the encoder parameters manually.
- If using a BiSS encoder ensure that P1 Calculation Time (03.060) is correct for the encoder. With some encoders this may need increasing from the default value. This may be specified on the encoder datasheet as tbusy.
- Replace the encoder.

Trip | Encoder 6
--- | ---
Value | 194
Short description | Encoder has indicated an error

This trip indicates that the encoder has indicated an error or that the power supply has failed to an SSI encoder. This trip can also indicate a wire break to an SSI encoder.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Check the wiring. Check that all data and clock signals are connected correctly and the screen is terminated correctly.
- For SSI encoders check the encoder power supply setting (P1 Supply Voltage (03.036)) and comms bits (P1 Comms Bits (03.035)).
- For a correctly configured BiSS or SC BiSS encoder this trip indicates that the encoder has detected an error, otherwise this trip will often occur if P1 Comms Bits (03.035) is not set correctly because a position or CRC bit may be read instead of the /Error bit.
- For EnDat or SC EnDat encoders this trip indicates that the encoder has detected an error.
- For SC Hiperface encoders this trip indicates that the encoder has detected an error.
- Replace the encoder / contact the supplier of the encoder.

Trip | Encoder 7
--- | ---
Value | 195
Short description | Set-up parameters for the position feedback device have changed

A set-up parameter for the position feedback device has been changed. See P1 Error Detection Level (03.040).

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Reset the drive to clear the trip and re-initialise the position feedback.

Trip | Encoder 8
--- | ---
Value | 196
Short description | Encoder communications time exceeds 250us

This trip indicates that the position feedback interface communications time exceeds 250us. The feedback device which has caused the trip can be identified by the sub-trip number.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Increase baud rate.
- Ensure the encoder is connected correctly.
- Ensure that the encoder is compatible.

Trip | Encoder 9
--- | ---
Value | 197
Short description | Selected motor control feedback source does not contain position feedback category option module

This indicates that the position feedback selected from an option slot that does not contain a position feedback category option module.

Recommended action:

- Check the setting of Motor Control Feedback Select (03.026) (or M2 Motor Control Feedback Select (21.021) if the second motor parameters have been enabled).
- Ensure that the option slot selected in Motor Control Feedback Select (03.026) has a feedback option module installed.

Trip | Encoder 11
--- | ---
Value | 161
Short description | Selected device type is not supported by the drive

This trip indicates that the drive hardware does not support the selected position feedback device type (see Control Board Identifier (11.067) for more information on control board capabilities).

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Upgrade drive to latest hardware version.

Trip | Encoder 12
--- | ---
Value | 162
Short description | Encoder could not be identified during auto-configuration

This trip indicates that the drive is communicating with the encoder but the encoder type is not recognised.

Sub-trip | Reason
1 | Drive position feedback interface 1
2 | Drive position feedback interface 2

Recommended actions:

- Enter the encoder setup parameters manually.
- Check to see if the encoder supports auto-configuration.

Trip | Encoder 13
--- | ---
Value | 163
Short description | Data read from the encoder is out of range during auto-configuration

This trip indicates that the data read from the encoder was out of range during auto-configuration. No parameters will be modified with data read from the encoder as a result of auto-configuration. The tens in the sub-trip number (indicated by the x in the table below) indicate the interface number (i.e. 1 for P1 interface and 2 for P2 interface).

Sub-trip | Reason
x1 | Rotary lines per revolution error
x2 | Linear comms pitch error
x3 | Linear line pitch error
x4 | Rotary turns bits error
x5 | Communications bits error
x6 | Calculation time is too long
x7 | Line delay measured is longer than 5us

Recommended actions:

- Enter the encoder setup parameters manually.
- Check to see if the encoder supports auto-configuration.

Trip | Encoder 14
--- | ---
Value | 164
Short description | Data in the additional configuration parameter is out of range

The data given in the additional configuration parameter for a position feedback interface is out of range. If the sub-trip number is one then the data is out of range in P1 Additional Configuration (03.074), or if the sub-trip number is 2 the data is out of range in P2 Additional Configuration (03.174). Not all position feedback devices use the additional configuration, but those that do are listed below.

BiSS
Range checking is applied to the turns padding (decimal digits 5-3) and position padding (decimal digits 2-0). If these give a padding value outside +/-16 then the trip is initiated. Note that in each case the most significant digit indicates left (0) or right (1) padding, and the least significant 2 digits indicate the number of bits.

Trip | External Trip
--- | ---
Value | 6
Short description | External Trip has occurred

External trip is initiated as shown in the table below.

Sub-trip | Reason
1 | External Trip Mode (08.010) = 1 or 3 and Safe Torque Off Input 1 is low
2 | External Trip Mode (08.010) = 2 or 3 and Safe Torque Off Input 2 is low
3 | External Trip (10.032) = 1

Recommended actions:

- Check the Safe Torque Off signal voltage on terminal 31 is 24V.
- Check the value of STO Input 01 State (08.009) which indicates the digital state of terminal 31.
- If external trip detection of the Safe Torque Off input is not required, set External Trip Mode (08.010) to Off (0).
- Check the value of External Trip (10.032).
- Select "Destinations" (or enter 12001) in Pr mm.000 and check for a parameter controlling External Trip (10.032).
- Ensure External Trip (10.032) or User Trip (10.038) (=6) is not being used by serial comms.

Trip | I/O Overload
--- | ---
Value | 26
Short description | Digital output overload

This trip indicates that the total current drawn from the 24V user supply or from the digital output has exceeded the limit. A trip is initiated if one or more of the following conditions:

- Maximum output current from one digital output is 100mA.
- The combined maximum output current from outputs 1 and 2 is 100mA.
- The combined maximum output current from output 3 and +24V output is 100mA.

Recommended actions:

- Check total loads on digital outputs.
- Check control wiring is correct.
- Check output wiring is undamaged.

Trip | Inductance
--- | ---
Value | 8
Short description | Inductance measurement out of range or motor saturation not detected

This trip occurs in RFC-S mode when the drive has detected that the motor inductances are not suitable for the operation being attempted. The trip is either caused because the ratio or difference between Ld and Lq is too small or because the saturation characteristic of the motor cannot be measured.

If the inductance ratio or difference is too small this is because one of the following conditions is true:

(No-load Lq (05.072)- Ld (05.024)) / Ld (05.024) < 0.2

(No-load Lq (05.072) - Ld (05.024)) < (K / Full Scale Current Kc (11.061)) H

where:

Drive Rated Voltage (11.033) | K
200V | 0.0073
400V | 0.0146
575V | 0.0174
690V | 0.0209

If the saturation characteristic of the motor cannot be measured this is because when the flux in the motor is changed the measured value of Ld does not change sufficiently due to saturation to be measured. When half of Rated Current (05.007) is applied in the d axis of the motor in each direction the inductance must change by at least (K / (2 x Full Scale Current Kc (11.061))) H.

The specific reasons for each of the sub-trips are given in the table below.

Sub-trip | Reason
1 | The inductance ratio or difference is too small when the drive has been started in sensorless mode.
2 | The saturation characteristic of the motor cannot be measured when the drive has been started in sensorless mode.
3 | The inductance ratio or difference is too small when an attempt is made to determine the location of the motor flux during a stationary auto-tune in RFC-S mode. This trip is also produced when the inductance ratio or inductance difference is too small when carrying out a phasing test on starting in RFC-S mode. If position feedback is being used the measured value for Position Feedback Phase Angle (03.025) may not be reliable. Also the measured values of Ld (05.024) and No-load Lq (05.072) may not correspond to the d and q axis respectively.
4 | The direction of the flux in the motor is detected by the change of inductance with different currents. This trip is initiated if the change cannot be detected when an attempt is made to perform a stationary auto-tune when position feedback is being used, or to perform a phasing test on starting in RFC-S mode.

Value | 103
Short description | Multi-module drive interconnection cable error

This trip is also initiated if the number of modules present changes from the number of modules detected at power-up. In this case the sub-trip is the number of modules that are still communicating correctly.

Short description | Island supply condition detected in regen mode

This trip indicates that a regen system is connected to an island supply. The sub-trips indicate the reason for the trip.

Sub-trip | Reason

Short description | Keypad has been removed when the drive is in keypad mode

If keypad reference mode is enabled (Reference Selected Indicator (01.049) = 4 or 6) (i.e. Reference Selector (01.014) is set to 4 or 6 if motor map 1 is selected, or M2 Reference Selector (21.003) is set to 4 or 6 if motor map 2 is selected) and the keypad removed, then this trip is initiated.

Recommended actions:

- Re-install keypad and reset.
- Change Reference Selector (01.014) to select the reference from another source.

Trip | Line Sync
--- | ---
Value | 39
Short description | Synchronization to the power supply has been lost

Recommended actions:

- Check the supply / supply connections to the regen drive.

Trip | Low Load
--- | ---
Value | 38
Short description | The load on the drive has fallen below the Low Load Detection Level

This trip is initiated if the low load detector is set up to produce a trip on low load detection and this condition occurs. See Enable Trip On Low Load (04.029).

Trip | Motor Too Hot
--- | ---
Value | 20
Short description | Motor thermal protection overload timed out

This trip indicates a motor thermal overload based on the Rated Current (05.007) and Motor Thermal Time Constant 1 (04.015). Motor Protection Accumulator (04.019) displays the motor temperature as a percentage of the maximum value. The drive will trip on Motor Too Hot when Motor Protection Accumulator (04.019) gets to 100%.

Recommended actions:

- Ensure the load is not jammed / sticking.
- Check the load on the motor has not changed.
- If seen during an auto-tune test in RFC-S mode, ensure the Rated Current (05.007) is = Heavy duty current rating of the drive.
- Tune the Rated Speed (05.008) (RFC-A mode only).
- Check feedback signal for noise.

Trip | Name Plate
--- | ---
Value | 176
Short description | Electronic nameplate transfer has failed

This trip is initiated if there is a problem detected when an electronic name plate transfer from the motor to the drive is initiated. The reasons for the trip are given below:

Sub-trip | Reason | Details
1 | A communication error with the encoder has been detected. | It is unlikely that this sub-trip will occur as most encoder errors will cause and encoder trip. It is possible that incorrect data in the nameplate could cause this trip, and so the nameplate data should be verified.
2 | A data error has been detected in the nameplate. This is either because the number of entries is out of range, i.e. less than 1 or greater than 168, or the calculated CRC does not match the CRC from the nameplate. | Either there is no valid nameplate in the position feedback device or there is a data error in the nameplate area.
3 | The exchange with the encoder has timed out. | If the encoder is connected to a drive interface, then this occurs because the encoder is not connected to the drive or is not initialised. If the encoder is connected to an option module interface, then this occurs because the position feedback interface (i.e. P1 or P2) is not present on the option module, or a suitable position feedback device is not selected, or because no device is connected, or it is not initialised.

--- | ---
Value | 22
Short description | Power stage over temperature

This trip indicates that a power stage over-temperature has been detected. The sub-trip "xxyzz" indicates which thermistor is indicating the over-temperature. The thermistor numbering is different for a single module type drive (i.e. no parallel board fitted) and a multi-module type drive (i.e. parallel board fitted with one or more power modules) as shown below:

Trip | OI Brake
--- | ---
Value | 4
Short description | Braking IGBT over current detected or short circuit protection for the braking IGBT activated

This trip indicates that an over-current has been detected in braking IGBT or braking IGBT protection has been activated. The braking IGBT over-current trip is detected within the power system. If the drive is a single module drive then there is no sub-trip. If the drive is a multi-power module drive the following sub-trip is used to indicate the source of the trip.

Source | xx | y | zz
Power system | 01 | Rectifier number* | 00: Rectifier snubber over-current trip detected.

*For a parallel power-module system the rectifier number will be one as it is not possible to determine which rectifier has detected the fault.

Recommended actions:

- Ensure the internal EMC filter is installed.
- Ensure the motor cable length does not exceed the maximum for selected switching frequency.
- Check for supply voltage imbalance.
- Check for supply disturbance such as notching from a DC drive.
- Check the motor and motor cable insulation with a Megger.
- Fit an output line reactor or sinusoidal filter.

Trip | Option Disable
--- | ---
Value | 215
Short description | Option module did not acknowledge during drive mode changeover

During drive mode changeover option modules must acknowledge that they have stopped accessing the communications system between the option slots and the drive. If an option module does not do this in the allowed time then this trip is produced.

Recommended actions:

- Reset the trip.
- If the trip persists, replace the option module.

Trip | Out Phase Loss
--- | ---
Value | 98
Short description | Phase loss been detected at the output of the drive

This trip indicates that phase loss has been detected at the drive output.

Sub-trip | Reason
1 | U phase output not connected when drive is enabled*
2 | V phase output not connected when drive is enabled*
3 | W phase output not connected when drive is enabled*
4 | Output phase loss detected when the drive is running
5 | U phase lower IGBT failure detection on drive enable

*These sub-trips could also indicate that the upper IGBT has failed in the indicated phase.

Recommended actions:

- To disable the trip set Output Phase Loss Detection Enable (06.059) to zero.

Trip | Over Speed
--- | ---
Value | 7
Short description | Motor over speed has occurred

In open-loop mode, if the Output Frequency (05.001) exceeds the threshold set in Over Speed Threshold (03.008) in either direction, an Over Speed trip is produced. In RFC-A and RFC-S modes, if the Speed Feedback (03.002) exceeds the threshold set in Over Speed Threshold (03.008) in either direction, an Over Speed trip is produced. If Over Speed Threshold (03.008) is set to 0.0 the threshold is then equal to 1.2 x the value set in Maximum Reference Clamp (01.006).

In RFC-A and RFC-S modes if an SSI encoder is being used and P1 SSI Incremental Mode (03.047) is set to Off, an Over Speed trip will be produced when the encoder passes through the boundary between its maximum position and zero.

Recommended actions:

- Reduce the Speed Controller Proportional Gain Kp1 (03.010) to reduce the speed overshoot (RFC-A and RFC-S modes only).
- If an SSI encoder is being used, set P1 SSI Incremental Mode (03.047) to On.

The above description relates to a standard over speed trip, however in RFC-S mode it is possible to produce an Overspeed trip with sub-trip 1. This is caused if the speed is allowed to exceed the safe level in RFC-S mode with flux weakening. See Enable High Speed Mode (05.022) for details.

Trip | Over Volts
--- | ---
Value | 2
Short description | DC bus voltage has exceeded the peak level or maximum continuous level for a period of time

This trip indicates that the DC bus voltage has exceeded VM_DC_VOLTAGE[MAX], or the DC bus voltage has been higher than the maximum continuous voltage level for a period of time. The trip threshold varies depending on voltage rating of the drive as shown below.

Voltage rating | VM_DC_VOLTAGE[MAX] | Maximum continuous voltage level
200 | 415 | 410
400 | 830 | 815
575 | 990 | 970
690 | 1190 | 1175

The exact cause of the trip can be identified by the sub-trip number.

Source | xx | y | zz
Control system | 00 | 0 | 01: Instantaneous trip when the d.c. link voltage exceeds VM_DC_VOLTAGE[MAX].
Control system | 00 | 0 | 02: Time delayed trip indicating that the d.c. link voltage has been above the maximum continuous voltage level for a period of time.
Active input converter | 00 | 1 | 00: Instantaneous trip when the d.c. link voltage exceeds VM_DC_VOLTAGE[MAX].

Recommended actions:

- Increase deceleration ramp.
- Connect a braking resistor to the drive.
- Decrease the braking resistor value (staying above the minimum value).
- If no braking resistor is fitted ensure that a standard ramp mode is selected in Ramp Mode (02.004).
- Enable S-ramps.
- Check nominal AC supply level.
- Check motor insulation using a Megger.
- If the trip occurs when the drive is not enabled,

- Check for supply disturbances which could cause the DC bus level to rise.
- Remove the internal EMC filter.

Trip | Phase Imbalance
--- | ---
Value | 104
Short description | Phase imbalance has been detected (Regen mode only)

The level of supply phase imbalance has cause the negative phase sequence components to exceed the threshold defined by Phase Imbalance Threshold (03.040) .

Trip | Phase Loss
--- | ---
Value | 32
Short description | Phase loss detected at the supply input to the drive

This trip indicates that the drive has detected an input phase loss or large supply imbalance. Phase loss can be detected directly from the supply where the drive has a thyristor base charge system (Frame size 7 and above). If phase loss is detected using this method the drive trips immediately and the xx part of the sub-trip is set to 01. In all sizes of drive phase loss is also detected by monitoring the ripple in the d.c. link voltage in which case the drive attempts to stop the drive before tripping unless bit 2 of Action On Trip Detection (10.037) is set to one. When phase loss is detected by monitoring the ripple in the d.c. link voltage the xx part of the sub-trip is zero.

Source | xx | y | zz
Control system | 00 | 0 | 00: Phase loss detected from d.c. link ripple
Power system (1) | 01 | Rectifier number (2) | 00: Phase loss detected directly from the supply

(1) Input phase loss detection can be disabled when the drive required to operate from the DC supply or from a single phase supply in Input Phase Loss Detection Mode (06.047).

(2) For a parallel power-module system the rectifier number will be one as it is not possible to determine which rectifier has detected the fault.

This trip does not occur in regen mode.

Recommended actions:

- Check that the input power supply connections are good and tightened correctly.
- Check the AC supply voltage balance and level at full load.
- Check the DC bus ripple level with an isolated oscilloscope.
- Check the output current stability.
- Reduce the duty cycle.
- Reduce the motor load.
- Disable the phase loss detection by setting Input Phase Loss Detection Mode (06.047) to Disabled.

Trip | Phasing Error
--- | ---
Value | 198
Short description | Incorrect phase offset angle in RFC-S mode

If position feedback is being used this trip indicates that the phase offset angle in Position Feedback Phase Angle (03.025) (or M2 Position Feedback Phase Angle (21.020) if the second motor map is being used) is incorrect and that the drive is unable to control the motor correctly.

Recommended actions:

- Check the encoder wiring.
- Check the encoder signals for noise with an oscilloscope.
- Check encoder mechanical coupling.
- If using an SC SC encoder, perform a re-initialisation of the encoder by setting Initialise Position Feedback (03.075) to 1.
- Perform an auto-tune to measure the encoder phase angle or manually enter the correct phase angle into Position Feedback Phase Angle (03.025).
- Spurious Phasing Error trips can sometimes be seen in very dynamic applications. This trip can be disabled by setting Over Speed Threshold (03.008) to a value greater than zero.

If sensorless control is being used this indicates that significant instability has occurred and the motor has accelerated without control. For low saliency motors (Active Saliency Torque Mode (05.066) < 2) this operates in the same way as when position feedback is used, based on the speed of the motor and the voltages applied. For high saliency motors (Active Saliency Torque Mode (05.066) = 2) this type of detection cannot be used and the over-speed trip should be used instead. However this trip is used for high saliency motors when low speed control using current injection is being used (Active Saliency Torque Mode (05.066) = 2) and control is lost because the motor has become non-salient. The saliency of most permanent magnet motors reduces with load, and so Low Speed Sensorless Mode Current (05.071) must be set to a level to limit the current so that the motor remains salient enough for control.

Recommended actions:

- Ensure that the motor parameters are set-up correctly.
- Reduce the speed controller gains.
- If high saliency control is being used ensure that Low Speed Sensorless Mode Current (05.071) is set to a low enough level, so that the motor remains salient at low speeds and higher loads.
- This trip can be disabled by setting Over Speed Threshold (03.008) to a value greater than zero.

Trip | Power Comms
--- | ---
Value | 90
Short description | Communications problem within the power system of the drive

A Power Comms trip indicates a communications problem within the power system of the drive. The reason for the trip can be identified by the sub-trip number.

Type of drive | xx | y | zz
Single power module system | 01 | Rectifier number* | 00: Excessive communications errors detected by the rectifier module.
Drive with active rectifier | 01 | 0 | 00: Communications with the active rectifier control has been lost. XX: Where XX > 00 indicates an internal (HF) fault in the control system for the active input converter if present. See Trip 0 (10.020).
Drive with active rectifier | 01 | 1 | 00: The active rectifier control board is in bootloader mode.

*For a parallel power-module system the rectifier number will be one as it is not possible to determine which rectifier has detected the fault.

Recommended actions:

- Hardware fault - contact the supplier of the drive. This does not apply if the sub-trip is 1100 which indicates that the active rectifier bootloader has been activated.

Trip | Power Data
--- | ---
Value | 220
Short description | Power system configuration/rating data error

This trip can be generated either from the drive control system or from the power system.

This trip is produced if there is an error in the configuration data stored in the power system. If the source of the trip is the control system then the trip related to the table that is uploaded from the power system at power-up.

Source | xx | y | zz
Control system | 00 | 0 | 02: There is no data table to be uploaded to the control board.
Control system | 00 | 0 | 03: The power system data table is bigger than the space available in the control pod to store it.
Control system | 00 | 0 | 04: The size of the table given in the table is incorrect
Control system | 00 | 0 | 05: Table CRC error.
Control system | 00 | 0 | 06: The version number of the generator software that produced the table is too low, i.e. a table from a newer generator is required that includes features that have been added to the table that may not be present.
Control system | 00 | 0 | 07: The power board data table does not match the power board hardware identifier.
Power system | 01 | 0 | 00: The power data table used internally by the power module has an error. (For a multi-power module drive this indicates any error with the code tables in the power system.)
Power system | 01 | 0 | 01: The power data table that should be uploaded to the control system on power up has an error.
Power system | 01 | 0 | 02: The power data table used internally by the power module does not match the hardware identification of the power module.

Recommended actions:

- Hardware fault - contact the supplier of the drive.

Trip | Power Down Save
--- | ---
Value | 37
Short description | Error detected in the power down save parameter data saved in non-volatile memory

This trip indicates that an error has been detected in the power down save parameters stored in non-volatile memory.

On drives other than Digitax HD, Power down save parameters are saved when the drive enters the under voltage state after the supply has been removed. This trip can occur if the d.c. bus is discharged too quickly after the supply is removed as the drive then doesn't have enough time to save these parameters before the internal power supply in the drive shuts down resulting in corruption of the saved data.

Recommended actions:

- Perform a 1001 save in Pr mm.000 to ensure that the trip doesn't occur the next time the drive is powered up.
- Check to see if an external discharge resistor is a connected to the d.c. bus when the supply is removed and if so, disconnect this resistor. If it is necessary to discharge the d.c. bus quickly after the supply is removed, then wait for at least 0.5s after the drive enters the under voltage state before connecting the discharge resistor.

Trip | PSU
--- | ---
Value | 5
Short description | Internal power supply fault

This trip indicates that one or more internal power supply rails are outside limits or overloaded.

Source | xx | Y | zz
Control system | 00 | 0 | 00: Internal power supply overload.
Active input converter | 00 | 1 | 00: Internal power supply overload.
Power system | Power module number | Rectifier number* | 00: Rectifier internal power supply overload.

*For a parallel power-module system the rectifier number will be zero as it is not possible to determine which rectifier has detected the fault.

Recommended actions:

- Remove any option modules and perform a reset.
- Remove encoder connection and perform a reset.
- Hardware fault within the drive - return the drive to the supplier.

Trip | PSU 24V
--- | ---
Value | 9
Short description | 24V internal power supply overload

The total user load of the drive and option modules has exceeded the internal 24V power supply limit. The user load consists of the drive digital outputs and main encoder supply. If the sub-trip code is 100, this indicates that this fault has been detected by the control board for the active input converter if present.

Recommended actions:

- Reduce the load and reset.
- Provide an external 24V power supply on control terminal 2.
- Remove all option modules.

Trip | Rating Mismatch
--- | ---
Value | 223
Short description | Voltage or current rating mismatch between power modules in a multi-module drive

This trip indicates that there is a voltage rating or current rating mismatch in a multi-module drive system. This trip is only applicable to modular drives that are connected in parallel. A mixture of power modules with different voltage or current ratings within the same multi-module drive system is not allowed and will cause a Rating Mismatch trip.

Recommended actions:

- Ensure that all modules in a multi-modular drive system are of the same frame size and rating (voltage and current).
- Hardware fault - contact the supplier of the drive.

Trip | Rectifier Set-up
--- | ---
Value | 94
Short description | A rectifier has not been set-up correctly in a multi-power module system

A rectifier has not been set-up correctly in a multi-power module system.

Trip | Resistance
--- | ---
Value | 33
Short description | Stator resistance measurement failed or value exceeds the allowed range

This trip indicates that either the value being used for motor stator resistance is too high or that an attempt to do a test involving measuring motor stator resistance has failed. The maximum for the stator resistance parameters is generally higher than the maximum value that can be used in the control algorithms. If the value exceeds (VFS / sqrt(2)) / Full Scale Current Kc (11.061), where VFS is the full scale d.c. link voltage defined by VM_DC_VOLTAGE, then this trip is initiated. If the value is the result of a measurement made by the drive then sub-trip 1 is applied, or if it is because the parameter has been changed by the user then sub-trip 3 is applied. During the stator resistance section of auto-tuning an additional test is performed to measure the drive inverter characteristics to provide the compensation necessary for dead-times. If the inverter characteristic measurement fails then sub-trip 2 is applied.

Sub-trip | Reason
1 | Measured stator resistance exceeded the allowed range
2 | It was not possible to measure the inverter characteristic
3 | The stator resistance associated with either motor map exceeds the allowed range

Recommended actions:

- Check that a value has not been entered in the stator resistance for either motor map does not exceed the allowed range.
- Check the motor cable / connections.
- Check the motor phase to phase resistance at the drive terminals.
- Check the motor phase to phase resistance at the motor terminals.
- Ensure the stator resistance of the motor falls within the range of the drive model.
- Check the integrity of the motor stator winding using an insulation tester.
- Select fixed boost mode (Open-loop Control Mode (05.014) = Fixed) and verify the output current waveforms with an oscilloscope.
- Replace the motor.

Trip | Slot1 Different
--- | ---
Value | 204
Short description | Option module in slot 1 has changed

If the option module fitted in option slot 1 is different in any way to the option module present at the last power-down, then this trip is produced. Option modules can define the structure of their set-up and applications menus provided by the drive. This trip is initiated if a different module is fitted, but also if the structure of the menus provided by the option module has changed. The priority order for the option module different trips is Slot1 Different highest, then Slot2 Different, then Slot3 Different then Slot4 Different. The sub-trip indicates the reason for the trip as given below.

Sub-trip | Reason | Defaults loaded
1 | No module was fitted previously | Set-up and application menus
2 | A module with the same identifier is fitted, but the set-up menu for this option slot has been changed. | Set-up menu
3 | A module with the same identifier is fitted, but the applications menu for this option slot has been changed. | Applications menu
4 | A module with the same identifier is fitted, but the set-up and applications menu for this option slot have been changed. | Set-up and application menus
>99 | Shows the identifier of the module previously fitted. | Set-up and application menus

The trip can be reset and the module will operate correctly. If sub-trips 2 to 4 occur, then no further action is required and the trip will not occur on a subsequent power-up. If any other sub-trips occur a parameter save is required to prevent further trips on a subsequent power-up.

Recommended actions:

- Turn off the power, ensure the correct option modules are installed in the correct option slots and re-apply the power.
- Confirm that the currently installed option module is correct, ensure option module parameters are set correctly and perform a user save in Pr mm.000.

Recommended actions:

- See relevant Option Module User Guide for details of the trip.

Trip | Slot1 HF
--- | ---
Value | 200
Short description | Fault with the option module in slot 1 that means that this module cannot operate

This trip indicates that there is a fault with the option module in option slot 1 that means that this module cannot operate. The possible causes of the trip are given by the sub-trip value.

Sub-trip | Reason
1 | The module category cannot be identified.
2 | The option module provides the structure of its set-up menu (Menu 15) and applications menu (Menu 25). It has not supplied the required information to the drive.
3 | The option module requires memory space in the shared RAM between the drive and the option module to be able to pass communications messages to the drive. There is insufficient memory available to allocate the memory buffer for this module.
4 | The option module has not indicated that it is running correctly during drive power-up sequence.
5 | The option module has been removed after power-up or it has ceased to indicate to the drive processor that it is still active.
6 | The drive has indicated that it is about to change mode (e.g. Open-loop to RFC-A). The option module has not stopped accessing drive user parameters and acknowledged this indication.
7 | The drive has indicated that its processor is about to be reset. The option module has failed to acknowledge this indication.
8 | The option module provides the structure of its set-up menu (Menu 15) and applications menu (Menu 25). An error has occurred during the download process.
9 | The transfer of the set-up and applications menu structure information has taken more than 5s
10 | The CRC in the set-up menu structure table or the applications menu structure provided by the option module is incorrect.

Recommended actions:

- Ensure the option module is installed correctly.
- If the option module has been reprogrammed check that this process was followed correctly.
- Replace the option module.

Trip | Slot1 Not Fitted
--- | ---
Value | 203
Short description | Option module in slot 1 has been removed

Each option module fitted in the drive is identified at power-up and the option fitted is stored by the drive in its non-volatile memory. If an option module was fitted in slot 1 at power-down, but that option module has subsequently been removed before power up then this trip is produced. The sub-trip number gives the identification code of the option module that has been removed. The priority order for the option module not fitted trips is Slot1 Not Fitted highest, then Slot2 Not Fitted, then Slot3 Not Fitted then Slot4 Not Fitted. If a drive user parameter save is not initiated before the drive power is removed and re-applied this trip will occur again after the next power-up. Until a drive user parameter save is performed it is possible to refit the module, which will then prevent the trip from occurring, and retain the parameter settings in the set-up menu (Menu 15) and applications menu (Menu 25). If a user parameter save is performed while this trip is active, the drive is powered down, the module refitted and the drive powered up, defaults settings will be loaded for these menus.

Power system | 01 | Rectifier number* | Always zero

*For a parallel power-module system the rectifier number will be one as it is not possible to determine which rectifier has detected the fault.

Recommended actions:

- Hardware fault - contact the supplier of the drive.

Trip | Th Brake Res
--- | ---
Value | 10
Short description | Brake resistor over temperature

If hardware based braking resistor thermal monitoring is provided and the resistor overheats this trip is initiated. If the braking resistor is not present then this trip must be disabled with bit 3 of Action On Trip Detection (10.037) to prevent this trip.

Recommended actions:

- Check braking resistor wiring.
- Check braking resistor value is greater than or equal to the minimum resistance value.
- Check braking resistor insulation.

Trip | Th Short Circuit
--- | ---
Value | 25
Short description | Motor thermistor short circuit

This trip indicates that a temperature sensor connected to an analog input or terminal 15 on the position feedback interface (where applicable) has a low impedance (i.e. < 50 ohms). The cause of the trip can be identified by the sub-trip number.

Sub-trip | Reason | Recommended actions
1 | Analog input 1 | Check temperature feedback connection and cabling to analog input 1. Replace sensor. Check that the setting of Analog Input 1 Mode (07.007) is correct.
2 | Analog input 2 | Check temperature feedback connection and cabling to analog input 2. Replace sensor. Check that the setting of Analog Input 2 Mode (07.011) is correct.
3 | Analog input 3 | Check temperature feedback connection and cabling to analog input 3. Replace sensor. Check that the setting of Analog Input 3 Mode (07.015) is correct.
4 | Position feedback interface | Check temperature feedback connection and cabling to pin 15 of the position feedback interface. Replace sensor. Check that the setting of P1 Thermistor Fault Detection (03.123) is correct.

Trip | Thermistor
--- | ---
Value | 24
Short description | Motor thermistor over temperature

This trip indicates that a temperature sensor connected to one of the analog inputs or terminal 15 on the position feedback interface (15-way D-type connector) (where applicable) has indicated an over-temperature. The source of the trip can be identified by the sub-trip number.

Sub-trip | Reason | Recommended actions
1 | Analog input 1 | Check why the temperature measured by the sensor connected analog input 1 is too high. Check temperature sensor connection. Check that the setting of Analog Input 1 Mode (07.007) is correct
2 | Analog input 2 | Check why the temperature measured by the sensor connected analog input 2 is too high. Check temperature sensor connection. Check that the setting of Analog Input 2 Mode (07.011) is correct
3 | Analog input 3 | Check why the temperature measured by the sensor connected analog input 3 is too high. Check temperature sensor connection. Check that the setting of Analog Input 3 Mode (07.015) is correct
4 | Position feedback interface | Check why the temperature measured by the sensor connected to pin 15 of the position feedback interface is too high. Check temperature sensor connection. Check that the setting of P1 Thermistor Fault Detection (03.123) is correct

Trip | Undefined
--- | ---
Value | 110
Short description | Power system indicated a trip but did not identify the reason

In a standard drive this trip indicates that the power system has generated but did not identify the trip from the power system. The cause of the trip is unknown.

In a 4 quadrant drive this indicates that the input converter control system has initated a trip which is not included in the normal trip system. The sub-trip number indicates the reason for the trip. The value given corresonds to the values in Trip 0 (10.020).

Trip | User 24V
--- | ---
Value | 91
Short description | User 24V supply not present on control terminals when required

This trip is initiated if User Supply Select (06.072) = 1 or Low Under Voltage Threshold Select (06.067) = 1 or Backup Supply Mode Enable (06.068) = 1 and no user 24V present on the user 24V input. (Note that if an active input rectifier is present this trip could be produced with a sub-trip of 100. This simply indicates that the same error condition has been detected by the active input converter first.)

Recommended actions:

- Ensure that the user 24V supply is present on the control terminals.

Trip | User Prog Trip
--- | ---
Value | 96
Short description | Trip generated by an onboard user program

This trip can be initiated from within an onboard user program using a function call which defines the sub-trip number.

Recommended actions:

- Check the user program.

Trip | User Program
--- | ---
Value | 249
Short description | Onboard user program error

An error has been detected in the onboard user program image. The sub-trip indicated the reason for the trip.

Sub-trip | Reason | Comments
1 | Divide by zero |
2 | Undefined trip |
3 | Attempted fast parameter access set-up with non-existent parameter |
4 | Attempted access to non-existent parameter |
5 | Attempted write to read-only parameter |
6 | Attempted an over-range write |
7 | Attempted read from write-only parameter |
30 | The image has failed because either its CRC is incorrect, or there are less than 6 bytes in the image or the image header version is less than 5. | Occurs when the drive powers-up or the image is programmed. The image tasks will not run.
31 | The image requires more RAM for heap and stack than can be provided by the drive. | As 30.
32 | The image requires an OS function call that is higher than the maximum allowed. | As 30.
33 | The ID code within the image is not valid | As 30.
40 | The timed task has not completed in time and has been suspended. | Onboard User Program: Enable (11.047) is reset to zero when the trip is initiated.
41 | Undefined function called, i.e. a function in the host system vector table that has not been assigned. | As 40.
52 | Customisable menu table CRC check failed | As 30.
53 | Customisable menu table changed | Occurs when the drive powers-up or the image is programmed and the table has changed. Defaults are loaded for the user program menu and the trip will keep occurring until drive parameters are saved.
80 | *Image is not compatible with the control board | Initiated from within the image code.
81 | *Image is not compatible with the control board serial number | As 80.
100 | Image has detected and prevented attempted pointer access outside of the IEC task's heap area. |
101 | Image has detected and prevented misaligned pointer usage. |
102 | Image has detected an array bounds violation and prevented its access. |
103 | Image has attempted to convert a data type to or from an unknown data type, has failed and has shut itself down. |
104 | Image has attempted to use an unknown user service function. |
200 | User program has invoked a "divide" service with a denominator of zero. (Note that this is raised by the downloaded image and has therefore been given a distinct error code despite being the same fundamental problem as sub-trip 1.) |
201 | Parameter access is not supported. An attempt to read database other than the host drive. |
202 | Parameter does not exist. Database was host drive but the specified parameter does not exist. |
203 | Parameter is read-only. |
204 | Parameter is write-only. |
205 | Unknown parameter error. |
206 | Invalid bit present in parameter. The parameter does not contain the specified bit. |

Trip | User Save
--- | ---
Value | 36
Short description | Error detected in the user save parameter data saved in non-volatile memory

This trip indicates that an error has been detected in the user save parameters saved in non-volatile memory. For example, following a user save command, if the power to the drive was removed when the user parameters were being saved.

Recommended actions:

- Perform a user save in Pr mm.000 to ensure that the trip doesn't occur the next time the drive is powered up.
- Ensure that the drive has enough time to complete the save before removing the power to the drive.

Short description | Supply voltage is outside of the defined range in Regen mode

This trip is initiated if the Maximum Supply Voltage (03.027) is set to a non-zero value and the supply voltage is outside the range defined by Minimum Supply Voltage (03.026) and Maximum Supply Voltage (03.027) for more than 100ms.

Sub-trip | Reason
1 | Supply voltage is below Minimum Supply Voltage (03.026)
2 | Supply voltage is above Maximum Supply Voltage (03.027)

Recommended actions:

- Ensure the supply voltage is operating within the drive specification.
- Ensure Minimum Supply Voltage (03.026) and Maximum Supply Voltage (03.027) are set correctly.
- Check the supply voltage waveform using an oscilloscope.
- Reduce the level of supply disturbance.
- Set Maximum Supply Voltage (03.027) to zero to disable this trip.
