Cause : Output phase loss detected comes when the Output Phase Loss trip indicates that phase loss has been detected at the drive output.
Sub-trip & Reason given below:
1 - U phase detected as disconnected when drive enabled to run.
2 - V phase detected as disconnected when drive enabled to run.
3 - W phase detected as disconnected when drive enabled to run.
4 - Output phase loss detected when the drive is running.
Check motor and drive connections. To disable the trip set Output Phase Loss Detection Enable (06.059) = 0.
