Issue:
ATV61/ATV71 tripping circuit breaker 

Product Line:
Altivar ATV61/ ATV71

Environment:
All

Cause:
Circuit breaker keeps tripping when try and power up the drive.

Resolution:
The circuit breaker is tripping because it is sensing a short circuit or over current in the circuit. Before repowering the drive you will need to do a full diode check on the inputs and the outputs on the drive.
Do a visual on the drive with no power applied check to see if there are any burn marks on the drive.
Check the breaker settings to see if they may need to be adjusted.
