I am on a startup that has several VFDs and E3 overloads on Device Net. This morning when I walked in, 5 of 8 of the VFDs, PowerFlex 70s and PowerFlex 700s, were all displaying OverVoltage Faults. Apparently a powersurge occured through the area overnight. What I don't get is why the PowerFlex's did not fault reset. I always have logic, that worked in the past, to reset a fault automatically.
Code attached along with UDT assigned to bits for the PowerFlex command work via the Comm-20 D.
I had to manually reset all the faults using the HIM module attached to each drive
