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 to the factory for repair.
● Verify that the three-phase current is balanced with a current clamp meter.
● If it is balanced and the oPL1 fault still exists, return to the factory for repair.
The drive capacity is much larger than the
motor capacity
Ensure the capacity of the drive and motor match to each other.

Action and Reset
Action level
Pr.06-47
Action time
Pr.06-46
Pr.06-48: Use the setting value of Pr.06-48 first. If DC braking function activates, use that of Pr.06-
46.
Fault treatment parameter
Pr.06-45
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
Reset method
Manual reset
Reset condition
Immediately reset
Record
When Pr.06-45=1 or 2, oPL2 is a “Fault”, and the fault is recorded.
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 oPL2 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
