Common Fault Codes

Fault 12

HW OverCurrent – Hardware overcurrent detection has been triggered, indicating the output current has exceeded the drive's hardware current limit.
Check motor wiring for short circuits or ground faults. Verify motor nameplate data matches drive configuration. Inspect PM motor windings for insulation breakdown.

Fault 13

Ground Fault – A ground fault has been detected on the drive output, indicating current leakage to earth ground.
Disconnect motor and test insulation resistance with a megohmmeter. Inspect output wiring and motor cable for damaged insulation. Replace motor or cable if insulation resistance is below acceptable limits.

Fault 29

Analog Input Loss – The analog input signal has been lost or fallen below the configured minimum threshold.
Check the analog input wiring and signal source. Verify the signal level at the drive terminals. Review parameter settings for analog input loss action and signal range.

Fault 33

Auto Tune Fault – The auto-tune procedure for the PM motor has failed to complete successfully.
Ensure the motor is disconnected from the load during auto-tune if required. Verify motor nameplate data entered in drive parameters is correct. Re-run the auto-tune procedure and check for mechanical obstructions.

Fault 38

Phase Loss – Loss of one or more output phases has been detected, which can indicate a wiring fault or motor connection issue.
Inspect output wiring connections at the drive and motor terminals. Check for loose or broken conductors. Verify motor winding continuity with a multimeter.

Fault 63

Software Overcurrent – The software-level overcurrent threshold has been exceeded during operation.
Reduce load on the motor or increase the acceleration ramp time. Verify current limit parameters are set appropriately for the PM motor. Check for mechanical overload conditions in the driven equipment.

Fault 70

Power Unit – An internal power unit fault has been detected within the drive, which may relate to the PM module interface.
Cycle power to the drive and observe if the fault recurs. Reseat the 25-PM1-D4P0 peripheral module in its slot. If fault persists, the drive or module may require replacement or factory repair.

Fault 100

Parameter Checksum – A checksum error has been detected in the drive's stored parameters, indicating possible data corruption.
Reset parameters to factory defaults and re-enter all required settings. Re-run the PM motor auto-tune procedure. If the fault recurs after power cycling, the drive's non-volatile memory may be faulty.
