U-phase over-current before run

U-phase short circuit detected when the output wiring
detection is performed before the drive runs.

Check if the motor’s internal wiring and the UVW wiring of the drive output
terminal are correct.

Check the motor cable and remove causes of the short circuits, or replace the
cable before turning on the power

The Aoc occurs due to the short circuit or ground fault at the output side of the
drive. Check for possible short circuits between terminals with the electric meter:
B1 corresponds to U, V and W; DC- corresponds to U, V and W;
corresponds to U, V and W.
