Description
In drive module arg, drive unit hardware common mode overcurrent protection is triggered on the output of rectifier unit AC at position arg.
Consequences
The system cannot operate until the fault is corrected, and the system will enter the "system interruption" (SYS HALT) state.
Possible causes
The current difference between A and B is too large.
Recommended actions
Verify that the AC output does not suffer from a common short circuit or a short circuit to protective ground. Verify that the AC output load is within the specified range.
