We have an analog servo system called the PPMC (Parallel Port Motion Control) that can use analog velocity servo amps such as the Copley or AMC. Copley DOES make higher current servo amps, such as the 422. (180 V, 20 A peak).
The other way is our PWM servo amps and PWM controller. This is also capable of 120+ V at 20 A peak.
