Common Drive Fault Codes
- F001
- Motor Overcurrent
Check motor load, motor cable, and motor itself. Reduce acceleration time or motor current limit. - F002
- Motor Overtemperature
Check motor thermal protection settings. Ensure adequate motor cooling and ventilation. Verify motor is not overloaded. - F003
- Heatsink Overtemperature
Check ambient temperature and ventilation of the drive. Ensure drive is not overloaded or operating at maximum capacity for extended periods. - F004
- Output Phase Loss
Check output connections to the motor. Verify motor windings are intact. Inspect for loose connections. - F005
- Input Phase Loss
Check input power supply connections. Verify all three phases are present and stable. - F006
- Internal Fault
Perform a drive reset. If the fault persists, contact technical support for further diagnosis or potential replacement. - F007
- Communication Fault
Check communication cable connections and configuration. Verify communication parameters on both the drive and the master device.

Troubleshooting
Drive displays an overcurrent fault (F001) during motor startup.
Measure motor resistance and check for short circuits. Verify motor nameplate current against drive settings.
Reduce the drive's acceleration time or lower the motor current limit setting. Inspect motor cables for damage.
Motor runs erratically or at incorrect speeds.
Check motor connections and ensure they are secure. Verify encoder feedback is properly connected and configured if using vector control.
Re-verify motor parameters and control mode settings in the drive. Ensure the motor is not overloaded.
Drive fails to power on or display shows no activity.
Check main power supply voltage at the input terminals. Verify internal fuses or circuit breakers are not tripped.
Ensure correct input voltage is applied. If the issue persists, the internal power supply may require service.
Heatsink temperature warning or fault (F003).
Measure ambient temperature around the drive. Check if ventilation openings are blocked or if cooling fan is operational.
Ensure adequate airflow and proper installation clearances. Clean any dust or debris from the heatsink and fan.
