# Trips

Mode: RFC‑A

Trip 0 (10.020) to Trip 9 (10.029) store the most recent 10 trips that have occurred where Trip 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 the 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) (See Date/Time Selector (06.019)). 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 - HF19 | These are fatal problems that cannot be reset. All drive features are inactive after any of these trips occur. If a basic keypad is fitted it will show the trip, but the keypad will not function. 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 - 247 and Slot1 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 | Non-volatile media trips | Trip numbers 174, 175 and 177 - 188 | These trips are priority 5 during power-up
5 | Trips with extended reset times | OI ac and OI Brake | These trips cannot be reset until 10s after the trip was initiated.
5 | 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.
5 | Standard trips | All other trips |

Trips {HF01} to {HF19} 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 hardware fault during exception processing
{HF02} | CPU memory management fault is an exception that occurs because of a memory protection related fault
{HF03} | CPU has detected a Bus Fault. A Bus Fault is an exception that occurs because of a memory related fault for an instruction or data memory transaction. This might be from an error detected on a bus in the memory system.
{HF04} | CPU has detected a usage fault: A Usage Fault is an exception that occurs because of a fault related to instruction execution. This includes: an undefined instruction an illegal unaligned access invalid state on instruction execution an error on exception return. The following can cause a Usage Fault when the core is configured to report them: an unaligned address on word and half word memory access division by zero.
{HF05} | Reserved
{HF06} | Reserved
{HF07} | Watchdog failure
{HF08} | CPU Interrupt crash. Interrupt crash level indicated by subtrip number.
{HF09} | Free store overflow
{HF10} | Reserved
{HF11} | The HF11 trip indicates that a non-volatile memory comms error has occurred.
Sub-trip | Reason | Recommended action
1 | Non-volatile memory comms error. | Hardware fault - contact the supplier of the drive.
2 | EEPROM size is incompatible with the user firmware. | After 1min the drive will go to its bootloader. Re-program the drive with a compatible user firmware using Unidrive M Connect
{HF12} | Stack overflow
Sub-trip | Reason
1 | User program or derivative background stack overflow
2 | User program or derivative timed stack overflow
3 | Main system interrupt stack overflow
4 | Main system background stack overflow
{HF13} | Reserved
{HF14} | Reserved
{HF15} | Reserved
{HF16} | RTOS error (the background task has returned)
{HF17} | Reserved
{HF18} | The HF18 trip indicates that the internal flash memory has failed when writing option module parameter data. The reason for the trip can be identified by the sub-trip number.
Sub-trip | Reason
1 | Option module initialization timed out
2 | Programming error while writing menu in flash
3 | Erase flash block containing setup menus failed
4 | Erase flash block containing application menus failed
5 | Incorrect setup menu CRC contained in flash
6 | Incorrect application menu CRC contained in flash
{HF19} | The HF19 trip indicates that the drive firmware is partially or completely deleted. The drive is now in its bootloader and is waiting for a new image to be downloaded using UniMConnect. Once a new image is downloaded, the drive can run normally.

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.

Trip descriptions
Trips shown in the table below can be generated either from the drive control system or from the power system. The sub-trip number which is in the form xxyzz is used to identify the source of the trip. The digits xx are 00 for a trip generated by the control system or the number of a power module if generated by the power system. If the drive is not a multi-power module drive then xx will always have a value of 1 if the trip is related to the power system. The y digit is used to identify the location of a trip which is generated by a rectifier module connected to a power module. Where the y digit is relevant it will have a value of 1 or more, otherwise it will be 0. The zz digits give the reason for the trip and are defined in each trip description.

Over Volts | OHt dc bus
OI ac | Phase Loss
OI Brake | LF Power Comms
PSU | OI Snubber
OHt Inverter | Temp Feedback

Trips (alphabetical order)

Trip | C.Acc
--- | ---
Value | 185
Short description | Communication failure with NV media card detected

A communication failure has occurred with a NV media card. If this occurs during a data transfer to the card then the file being written may be corrupted. If this occurs when data is being transferred from the card then the data transfer may be incomplete. If a parameter file is transferred to the drive and this trip occurs during the transfer the parameters are not saved to non-volatile memory, and so the original parameters can be restored by powering the drive down and up again.

Recommended actions:

- Check the NV media card is installed / located correctly.
- Replace the NV media card.

Trip | C.by
--- | ---
Value | 178
Short description | NV media card in use

An attempt has been made to access a file on a NV media card, but the file is already being accessed be an Option Module. No data is transferred.

Recommended actions:

- Wait for the Option Module to finish accessing the NV media card and re-attempt the required function.

Trip | C.cPr
--- | ---
Value | 188
Short description | NV media card data and drive data is not the same

A compare has been carried out between a file on a NV media card and the drive and these are different and no other NV media card related trips have occurred.

Recommended actions:

- Set Pr mm.000 to 0 to reset the trip.
- Check to ensure the correct data block on the NV media card has been used for the compare.

Trip | C.d.e
--- | ---
Value | 179
Short description | NV media card data already exists

An attempt has been made to store data on a NV media card, but the file already exists. No data is transferred. The file should be erased first to prevent this trip.

Recommended actions:

- Erase the data in data location.
- Write data to an alternative data location.

Trip | C.dAt
--- | ---
Value | 183
Short description | Attempt to read non-existant data detected

An attempt has been made to access a non-existent file on a NV media card. No data is transferred.

Recommended actions:

- Ensure data block number is correct.

Trip | C.Err
--- | ---
Value | 182
Short description | NV media card data structure error detected

An attempt has been made to access a NV media card, but an error has been detected in the data structure on the card. Resetting this trip will cause the drive to erase the <MCDF> folder from the NV media card (if it exists) and create the correct folder structure. On an SD card, whilst this trip is still present, missing directories will be created, and if the header file is missing it will be created. The following sub-trip numbers are used with this trip.

Sub-trip | Reason
1 | The required folder and file structure is not present.
2 | The <000> file is corrupted.
3 | Two or more files in the <MCDF\> folder have the same file identification number.

Recommended actions:

- Erase all the data block and re-attempt the process.
- Ensure the card is located correctly.
- Replace the NV media card.

Trip | C.Ful
--- | ---
Value | 184
Short description | NV media card is full

An attempt has been made to write to a NV media card, but there is insufficient space available. No data is transferred.

Recommended actions:

- Delete a data block or the entire NV media card to create space.
- Replace the NV media card.

Trip | C.OPt
--- | ---
Value | 180
Short description | Option difference detected

A parameter file has been transferred from a NV media card to the drive, but the option module fitted is different between source and target drives. This trip does not stop the data transfer, but is a warning that the data for the option module will be set to the default values and not the values from the card. This trip also applies if a compare is performed between a parameter file on a card and the drive and the option module fitted is different between the source and target.

Recommended actions:

- Ensure the correct option modules are installed.
- Press the red reset button to acknowledge that the parameters for the option module installed will be at their default values.
- This trip can be suppressed by setting Pr mm.000 to 9666 and resetting the drive.

Trip | C.Pr

Recommended actions:

- Clear the read only flag by setting Pr mm.000 to 9777 and reset the drive. This will clear the read only flag for all data blocks in the NV media card.

Trip | C.rtg
--- | ---
Value | 186
Short description | Transfer of data between drives of different ratings detected

A parameter file has been transferred from a NV media card to the drive, but the current and/or voltage rating are different between source and target drive. This trip does not stop the data transfer, but is a warning that the data for rating dependent parameters may not be the same on the target as the source drive. This trip also applies if a compare (using Pr mm.000 set to 8yyy) is performed between a parameter file on the card on the drive.

Recommended actions:

- Reset the drive to clear the trip.
- This trip can be suppressed by setting Pr mm.000 to 9666 and resetting the drive.

Trip | C.Typ
--- | ---
Value | 187
Short description | Transfer of data between drives operating in different modes detected

This trip is produced during a compare if the drive mode in the file on the NV media card is different from the current drive mode and the file is a parameter file. This trip is also produced if an attempt is made to transfer a parameter file where the source and target drive modes are different and the drive mode is outside the range allowed for the target drive.

Recommended actions:

- Ensure the destination drive supports the drive operating mode in the parameter file.
- Clear the value in Pr mm.000 and reset the drive.
- Ensure destination drive operating mode is the same as the source parameter file.

Short description | Current feedback calibration range error

Current calibration range error.

Recommended actions:

- Hardware fault - contact the supplier of the drive.

Trip | D.Ch
--- | ---
Value | 97
Short description | Drive has become active while data is being updated

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 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 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
- Transferring user programs

Trip | dcct
--- | ---

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.

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 EEPROM Fail.xxx 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 loaded 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.

Value | 32
Short description | Input Phase Loss

This trip indicates that the drive has detected an input phase loss or large supply imbalance. The drive will attempt to stop the motor before the trip is initiated. If the motor cannot be stopped in 10 seconds the trip occurs. This trip works by monitoring the ripple voltage on the DC bus of the drive, if the DC buss ripple exceeds the threshold, the drive will trip on Phase Loss. Potential causes of the DC bus ripple are input phase loss, large supply impedance and severe output current instability.

Source | xx | y | zz
Control system | 00 | 0 | 00: Phase loss detected based on control system feedback. The drive attempts to stop the drive before tripping unless bit 2 of Action On Trip Detection (10.037) is set to one.

Short description | RAM allocation failure

An option module, derivative image or user program image has requested more parameter RAM than is allowed. The RAM allocation is checked in order of resulting sub-trip numbers, and so the failure with the highest sub-trip number is given. The sub-trip is calculated as (parameter size x 1000) + (parameter type x 100) + sub-array number. Note that if this trip occurs, all menu customisation provided by option modules, the derivative image or the user program image is not used. The tables below show the values corresponding to the parts of the sub-trip number.

Parameter size | Value
1 bit | 1
8 bit | 2
16 bit | 3
32 bit | 4
64 bit | 5

Value | 33
Short description | Resistance measurement failure

During auto-tune an attempt is made to measure the resistance of the motor connected to the drive. The drive will trip with one of the following sub-trip codes if a problem is encountered during the measurement.

Sub-trip | Reason
0 | Stator resistance is > (VFS / v2) / Full Scale Current Kc (11.061), where VFS is the full scale d.c. link voltage; or the result is = 100ohms.
1 | Reserved
2 | The measured Transient Inductance is > 500mH or the measured Stator inductance is > 5000mH.
3 | A resistance value entered by the user is > (VFS / v2) / Full Scale Current Kc (11.061), where VFS is the full scale d.c. link voltage. Clear this trip by setting Stator Resistance (05.017) to a value that is in range and reseting the drive.
4 | The measured stator resistance is not > than the sub-trip 0 checks but is outside the firmware usable range for this drive size.

Recommended actions:

- Ensure the stator resistance of the motor falls within the range of the drive model. The most likely cause of this trip is trying to measure a motor much smaller than the drive rating. Ratio's of drive size to motor size of > 15:1 are likely to lead to problems.
- Check that a value has not been entered in the Stator Resistance for the presently selected motor map that exceeds the allowed range.
- Check the motor cable / connections.
- Check the integrity of the motor stator winding using an insulation tester.
- Check the motor phase to phase resistance at the drive terminals.
- Check the motor phase to phase resistance at the motor terminals.
- Select fixed boost mode (Open-loop Voltage Mode (05.014) = Fixed) and verify the output current waveforms with an oscilloscope.
- Replace the motor.

Trip | SL.dF
--- | ---
Value | 204
Short description | Option module has changed

If the option module fitted in option slot 1 is different to the option module present at the last power-down then this trip is produced. The sub-trip number gives the identification code of the module that was originally fitted. Drive user parameters must be saved to prevent this trip on the next power-up if the module has changed. If the menus have been changed, but not the module, the trip will not occur on the next power-up. The sub-trip number gives the following indications of the reason for the trip.

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

Recommended actions:

- Turn off the power, ensure the correct option module is installed 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.

Trip | SL.Er
--- | ---
Value | 202
Short description | Error generated by the option module

The option module in option slot 1 has indicated an error. The option module can give the reason for the error and this is shown in the sub-trip number. As default the sub-trip number is shown as a number on the display, however, it is possible for the option module to supply sub-trip number strings which will be displayed instead of the number if available.

Recommended actions:

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

Trip | SL.HF
--- | ---
Value | 200
Short description | Error in communication with an option module

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 | All the required customisable menu table information has not been supplied or the tables supplied are corrupt
3 | There is insufficient memory available to allocate the comms buffers for this module.
4 | The module has not indicated that it is running correctly during drive power-up
5 | The module has been removed after power-up or it has ceased to indicate to the drive processor that it is still active.
6 | The module has not indicated that it has stopped accessing drive parameters during a drive mode change
7 | The module has failed to acknowledge that a request has been made to reset the drive processor.
8 | The drive failed to read the menu table from the module correctly during drive power-up.
9 | The drive failed to upload menu tables from the module and timed-out (5s).
10 | Menu table CRC invalid.

Recommended actions:

- Ensure the option module is installed correctly.
- Replace the option module.
- Replace the drive.

Trip | SL.nF
--- | ---
Value | 203
Short description | Option module no longer fitted

Any 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. Drive user parameters must be saved to prevent this trip on the next power-up.

Recommended actions:

- Ensure the option module is installed correctly.
- Re-install the option module.
- To confirm that the removed option module is no longer required perform a save function in Pr mm.000.

Trip | SL.tO
--- | ---
Value | 201
Short description | Option module has not updated the option watchdog

This trip indicates that the option module in option slot 1 has started the option watchdog function and then failed to service this watchdog correctly.

Recommended actions:

- Replace the option module.

Trip | So.St
--- | ---
Value | 226
Short description | Soft start hardware failure

This trip indicates that the soft soft start system has remained active when it should be inactive. For a resistor based soft start this means that the soft start shorting relay has not closed. On 110V drives it also indicates that one of the DC link capacitors has failed.

Sub-trip | Reason
1 | The soft start system has failed.
2 | A DC bus capacitor has failed (110V drives only)

Recommended actions:

- Hardware fault - contact the supplier of the drive.

Trip | St.HF
--- | ---
Value | 221
Short description | Indicates that the drive had a Hardware fault on the last power down

If an HF01 to HF18 trip occurs then a Stored HF trip occurs each time the drive is powered up until this trip is reset. The sub-trip code is the number of the original HF trip. The Stored HF trip can only be reset by first writing 1299 to Pr mm.000 and resetting the drive.

Recommended actions:

- Enter 1299 into Pr mm.000 and press reset to clear the trip.

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.
34 | The user program image has been changed for an image with a different user program number. | 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. Reduce code in timed task or slow down the task repeat rate ( Onboard User Program: Clock Task Schedule Rate (11.055) ).
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. |
207 | Parameter format lookup failed. Failed to get parameter information data. |
208 | An over-range write has been attempted. |

The following table gives the differences when compared to the derivative product image.
