Common Fault Codes

Fault Code F002

Auxiliary Input fault. The drive has detected an open or inactive auxiliary input signal.
Check the wiring and status of the auxiliary input terminals. Verify that any external interlock or safety device connected to the auxiliary input is closed and functioning correctly.

Fault Code F003

Power Loss fault. Input power to the drive was lost or dropped below the acceptable threshold during operation.
Check incoming AC supply voltage for sags, phase loss, or interruptions. Verify all input fuses and the supply circuit breaker. Inspect input wiring connections for looseness or damage.

Fault Code F004

Undervoltage fault. DC bus voltage has fallen below the minimum operating threshold.
Measure the incoming AC line voltage and confirm it is within the specified range for the drive. Check for voltage sags or phase imbalance on the supply. Inspect the input rectifier and DC bus capacitors if the supply voltage is confirmed normal.

Fault Code F005

Overvoltage fault. DC bus voltage has exceeded the maximum allowable level, typically caused by regenerative energy from the motor during deceleration.
Increase the deceleration time parameter to reduce regenerative energy. If the application requires fast deceleration, consider adding a dynamic braking resistor. Verify that the incoming supply voltage is not elevated above the rated level.

Fault Code F006

Motor Stalled fault. The drive has detected that the motor is not accelerating as expected, indicating a stall condition.
Check for mechanical overload or jam on the driven equipment. Verify motor wiring and confirm the motor nameplate data entered in the drive parameters matches the actual motor. Increase the stall fault time parameter if nuisance tripping occurs during heavy load starts.

Fault Code F007

Motor Overload fault. The drive's electronic thermal overload protection has determined that the motor has been operating above its rated current for an extended period.
Check the mechanical load on the motor and reduce if possible. Verify that the motor overload current parameter is set correctly based on the motor nameplate FLA. Allow the motor and drive to cool before resetting the fault.

Fault Code F012

Hardware Overcurrent fault. The output current has exceeded the drive's instantaneous hardware overcurrent trip level.
Check for a short circuit in the motor cable or motor windings using an insulation resistance test. Verify that the motor cable length does not exceed the drive's specification. Inspect output power terminals for loose connections or phase-to-phase contact.

Fault Code F033

Auto-Tune fault. The drive was unable to complete the auto-tune procedure successfully.
Ensure the motor is disconnected from the mechanical load during auto-tune if possible. Verify that motor nameplate data (voltage, current, frequency, RPM, power) is correctly entered in the drive parameters before initiating auto-tune. Check motor wiring for open phases.
