Allen Bradley 1336 PLUS Drive - Restart After a Power Blip
Allen Bradley 1336 PLUS drive trips off after a power blip. Faults show power line loss and low bus fault.

Allen Bradley 1336 PLUS drive trips off after a power blip. Faults show power line loss and low bus fault. I'd appreciate if someone could shed light on the effectiveness of the following solution to the issue:

Disable Line Loss Fault (40) and Low Bus Fault (91) parameters. This would only disable the drive fault condition. If the voltage goes below the minimum allowed level, the drive will trip, however, with 2-wire start/stop control, should be able to re-start after the voltage is restored. This is because The START input (TB3-19) is a level detection that requires the input at TB3 terminal 19 to be a maintained input for the drive to run.

What are your thoughts? Any other ideas would be appreciated? Thanks
