My lathe is an OSP 2200 not mine but pretty much the same: http://www.youtube.com/watch?v=DgAUjRM-HXs > All the details of how that system works are proprietary to OKUMA and there > is no real way to find out anything other than buy a junker and try to > reverse engineer how it works. > Other then the encoders, it's pretty standard stuff. +-10v drives 12v spindle and MPG encoder The wiring diagram was pretty good for most things. I switched the encoders to incremental at first but then I upgraded the drives to AC servos as I blew one up while not paying attention. I didn't bother with the DC spindle drive either as I don't have 3 phase power. One of these days I'll finish it....
