Output phase loss (OPHL)
Unbalanced three-phase impedance of the motor - check the motor connection.
Check if the control board cable is loose. If yes, reconnect the cable and run the drive to test.
Warning setting parameter
Pr.06-45
0: Warn and keep operating
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
This problem also comes when you run drive without motor or rating of motor is small as compare to drive.
