My understanding is that some controls would synthesize the tach feedback from encoder feedback. If you have one of those, then it gets more complex (and I don't know the answer)
You can drive analog outputs and read encoder feedback using EMC2 with hardware from Mesa Electronics, Pico Systems, Motenc, Servo-to-go, and Vigilant. EMC2 closes the PID loop in the PC. - Steve ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
