Has anyone tried the Copley 422 drives with the SEM servo motors, mine are 142v and 30amps.
I know the copley 422 has high enough voltage but they are only 20amp,just wondering if they would still work or not.
Thanks Mike
They will work, but you will only get 2/3 of the peak torque. That may well be plenty.
In fact, the SEM motors are so strong, 20 A might break the belts or couplings.
