Pr. 06-47
Pr. 06-46
Pr. 06-48: Use the setting value of Pr. 06-48 first if there is DC braking function,

Pr. 06-45=1 or 2 is "Fault", and will be recorded.
Replace the motor.
Check the cable condition.
Replace the cable.
Choose a three-phase motor
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
Make sure the capacity of the drive and motor match to each other.
