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 t

Tuning with no load at all might be hard or impossible. Do you have the
motors attached to the ballscrew/machine?
Full speed at 0.4V command would

Can you tell me what your PID values you have in your setup? I know mine
won't bet the same but it gives me an idea on the range.
Thanks Wallace

Thanks for the replies
Month end so I'm busy finishing jobs at the moment !!!
The motor is attached to a ballscrew and encoder. Currecntly I only running
25 volts and the motor turns at approx 300 rpm full speed.
The servo is set to current mode and the maximum current is 10 amps.
