Output phase loss
U phase
(oPL1)
U phase output phase loss
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 continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
Pr.06-45 = 1 or 2 is “Fault”, and the fault is recorded.
Unbalanced three-phase
impedance of 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 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
Make sure the capacity of the drive and motor match to each other.
