Hey,

I just purchased a Hitachi VFD to go with my 3kw Chinese spindle. I went with the 10HP model which can run on 1 or 3 phase. The spindle is de-rated 50% since I am running a 4.3ish HP motor on single phase input.

Anyways, I set all my settings (well, maybe not all of them) and can get it to spin if I give it little help to get started. I can get it to spin either way. Without giving it a push start it will just sit and hum. Does anyone know what is going on? Hours of google turns up nothing. Any help would be greatly appreciated.

Alex
