What causes a bOF fault code on ATV61 and ATV71 drives?
All serial numbers, all model numbers.
Drive showing 'bOF' on the display.
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.
