    AC servo as spidle

    Hello,
    Does anyone know how to wire an ac servo as a spindle? My controller which is Chinese SMC55N, has PWM,+10v and CW/CCW and of course, a bunch of output signals for relays. The servo is a cheap (also) Chinese one, 3kw and require +10V, -10V, analog ground and DIR information for controlling it in Speed Mode.

    Does the controller come with a User manual?
    Or you can ask the maker to send you a PDF file.

    If this is a typical P.M. AC or BLDC servo, you cannot use a common VFD for a controller.
    I have tried it with very poor success.
