Oops, I completely missed the point of the question. I think this should work: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Closed_Loop_Spindle_Speed_Control except you will need a sensor for your AC, as you had planned, to feed into the software encoder phase A. A diode bridge could give you 120Hz. Then the encoder velocity output will go into a PID feedback input. The PRM command will go into the PID command input. The PID output will give you the value to feed to the throttle actuator (stepgen, pwmgen). -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ The modern datacenter depends on network connectivity to access resources and provide services.
