Hello guys and gals.
I have a large generac generator that is backup power for a wastewater pumpstation that has started getting "overspeed" alarm on startup. It starts for a few secs and then shuts down. It starts just fine not under load. It started fine under load for 5 years until now. The load has not changed but we recently replaced a few powerflex ab drives with scheider altivar drives. There is a harmonic filter assembly across the input of each drive. The generac tech said it was a glitch in software or controller and reset it by unplugging controller and having it reboot. It does it every startup under load now.
Anyone have any input on the issue? Is it possible the new drives could cause this?
Thanks for the replies.
