I picked this lathe up from auction and would like to get rid of the current electronics and set it up to run mach3 since it's was I use for a different machine.

It's an AC spindle run off a VFD.

Fanuc Servos-
.9kw
199volt
4.7amp
133hz
2000rpm
model b6/2000

I plan to swap over to a smooth stepper control setup for USB.

My main questions:

-How do I determine the proper power supply for the servos? I believe it has a 500va transformer right now?

-Are the fanuc servo amplifier the same as a driver? I would like to use gecko 320x drivers.

Thanks
