Have a 220 3 phase motor trying to get working. The wiring is easy. But when I turn it on the motor sounds like its spinning up, but is not moving. Sorta a noisy type of sound, more vibration type of sound. VFD is a cheap A2 series, the typical ones you see on ebay. Went though the programs didn't change much. should I change all hthe 400hz to 60? sems the videos I have watched leave these aloneIf you can offer any assistance that would be great.
Reply:Yes, back the top end setting down to 60 hertz.  Run 0-60 to change speed.

Reply:Was the drive new or used? If used it's time to read the programming manual & check the parameters that have been set by the prior user.
Reply:what was the same??if you revive a 3 year old thread,contribute quality info if you can.
Reply:Did you enter the motor name plate data, if so, it could be a switching freq. issue and you could quieten it down with a adjustment in the motor control parameters.  Just a thought. You may call the Mfg and get customer service to help.  Good luck.
