OK, so I got my VFD running on the drill press (3/4 hp 60 hz 3 phase Baldor motor hooked to a ABB VFD).
Thanks to everyone here for advise. Pretty simple to setup actually.
The motor whines at the lower speeds. It's nice and quiet at the upper end. I set the nominal frequency to the motor frequency at 60 Hz. I have been adjusting max frequency to see if it goes away. The lower end (lower 1/3-1/2) of the pot. speed scale generates a whine in the motor.
Any suggestions on how to minimize this?
Thanks,
Christian
