I'm about to tie up this Tree retrofit but have been having a heck of a time with the VFD. I'm still relatively noobish with VFDs but I've set up small, simpler ones without issue.
In the meantime, I've disconnected the spindle belt to just run the motor. I have the limits from 10 to 140Hz. Anything above 70Hz runs fine; pulls about 11amps once running and runs smooth. But when I go below 70Hz, it surges/hunts then throws and overcurrent alarm. Pulls around 50amps before it trips.
Can't seem to find anything nor figure anything out.
