Hi,

I am trying to put together the parts for a ORAC conversion. The lathe is still functional with, all original electronics on it.

So far, I do have a PlanetCNC control board, stepper motors, drives, power sources.

I need of help regarding the spindle encoder and VFD required.

Is anyone able to advise if the spindle encoder is a NPN or a PNP ?
What VFD would you recommend for the conversion?

thanks,
A
