Convert from Anilam Crusader M to EMC 2

One thing I forgot to mention is that when shopping for servo drive replacements (copley, AMC, etc), patience is your friend. I see that some Copley 423's are for sale for > $400, however, if you wait you might get them less than $100 each, just depends.

Another option is to use the Pico Systems PWM servo amps and PWM controller. (They can also be used with Mesa controller boards that can output PWM, if you already have the Mesa board.)

Jon,

Thanks for the info.
I assume your boards don't read the tachometer?

Right, our PWM system doesn't need the tach. And, if using our analog system (the PPMC) then the tachs only go to the servo amps, not the control.
