I was able to use the existing amps, power supply, encoders, tachometers, servos..... I just tied in the EMC signals to the amps and the encoder feedback to EMC. I used the 5i20 IIRC and the +-10V board, an I/O board plus 2 or 3 50 pin breakout boards. I have future plans to replace a Crusader II mill control with EMC2, I plan to wire EMC2 to the same plugs so I can remove the encoder plugs and larger control plug then plug it all into mating connectors for EMC2. That way if I need to mill some parts while the conversion is in progress, I can simply plug it all back into the crusader II control and run.
Since the amps are already tuned to the servos I used a command mostly of VFF and some P and I gain. VFF took care of the velocity command, P took care of the error correction, and integral took care of offsets that seem to change as the amps warm up. That's how I think it works anyway, could be wrong.
