I was wondering if it is at all possible to drive a 4 pole ac servo with a drive designed for a 6 pole motor. I have everything all hooked up and the motor just jitters. The motor is a baldor bsm80b ac servo, and the drive is an emerson fx-316 drive. The drive can't be set up for 4 poles as far as I know. Is there any trick to fool the drive??:confused: I don't need any positional accuracy. Just want it to spin.
Usually the drive is set for 60 degree phasing or 120 deg phasing and the commutation is taken care of by the hall effect or resolver sensor. Do you have the phasing right (motor phases) ?

I think I have the phasing right. Is there any way to check this? The servo leads are U,V,W, and R,S,T on the drive. Don't think they will match in order since they are different manuf.
What type of feedback do the Baldor use? Hall effect switches? they need to be phased correctly with the motor windings.

They use resolver feedback, and I aligned it as they recomend(emerson) for their drive. Wired the phases up all 6 different ways and still nothing.
