Hi all

Please help. After an power outage the ACS580 recognizes the DC undervoltage error, after power was restored it  then goes into limp mode, running inconsistently below 80% of the set frequency value. I've seen on the logs a lot of DC undervoltage errors happening in a small amount of time, like 10 errors in 2 minutes. This is most probably the cause for the limp mode.

Attached is a image of the current readings during this event. Rated motor current is 56A but running consistently below that.

Any suggestion of how I can implement a type of a automatic reset that can prevent this from happening?
