Cause : U-phase short circuit detected when 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.
The Aoc occurs due to 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, W; DC- corresponds to U, V, W; corresponds to U,
V, W.
