Cause Corrective Actions
Unbalanced three-phase
impedance of the motor
Replace the motor.
Check if the wiring is incorrect Check the cable and replace it if necessary.
Check if the motor is a
single-phase motor
Choose a three-phase motor.
Check if the current sensor is
broken
Check if the control board cable is loose. If yes, reconnect the cable and run the
drive to test. If the fault still exists, return to the factory for repair.
Check if the three-phase current is balanced with a current clamp meter. If the
current is balanced and the OPHL fault still exists, return to the factory for repair.
Check if the drive capacity is larger
than the motor capacity
Choose the drive that matches the motor capacity
