Cause  Corrective Actions 
The three-phase impedance of 
motor is unbalanced 
Replace the motor. 
The motor is wired incorrectly 
Check the cable condition. 
Replace the cable. 
Using a single-phase motor  Choose a three-phase motor 
The current sensor is damaged 
Check the flat cable of the control board. Re-do the wiring and test again if the 
flat cable is loose. If the fault still exists, return the unit to the factory. 
Verify that the three-phase current is balanced via a current clamp meter. If it is 
balanced and the OPHL fault still exists, return the unit to the factory 
The drive capacity is much larger 
than the motor capacity 
Make sure the capacity of the drive and motor match to each other.
