I'm running Colpey servo drives but I cannot get them tuned in with LinuxCNC.
The servo is a current drive with a +- 10 volt input. As there is not much load on the drive so a +-0.4 volt will swing the motor at full speed. The manual for the drive says to supply a stepped input to it and tune the feedback pot till the motor steps nicely without overshoot. Done this with a 1 HZ signal generator. Now when I'm runing it with LinucCNC, I get a lot of overshoot and eventually, if the step is big enougth, a following error. I've tried P, I and D values varying from .05 to 5 and output voltages from 1-10 and none seem to make any real improvement. I'm stuck.
