Issue:
BOF trip on ATV61/71.

Product Line:
ATV61, ATV71

Environment:
All serial numbers, all model numbers.

Cause:
N/A

Resolution:
If the DB resistor protection is set to Freewheel (yes), the drive faults on bOF on power up.  This is because the drive is looking for a DB resistor connected.
Set parameter brP (DB resistor Protection) to NO or check the resistor that is connected to the PA and PB connections.
