- 1
Inspect motor power cables for damage, proper termination, and loose connections at both the drive output terminals and the motor terminal box.
- 2
Verify drive parameters related to motor data (nominal voltage, current, frequency, RPM) are accurately configured to match the motor nameplate.
- 3
Perform a static auto-tuning procedure (if safe and permissible) to allow the drive to recalibrate its motor model and current sensing.
- 4
Check the integrity of all ground connections for the drive, motor, and shielded motor cables to ensure proper grounding.
- 5
Cycle main power to the AC drive and motor, then monitor if the CoF fault reoccurs upon restart or run command.
