If you mean a servo driver which accepts step and direction signals,
then they are all much the same. Gecko 320 and 340, and a number of the
Rutex drives are of this type. If you mean servo amps in general,
no. The old standard was a +/- 10 V signal to a velocity servo amplifier.
Copley Controls, Westamp, Servo Dynamics and others have many
amps of this type.

But, many newer servo amps accept commands on CanBus, devicenet,
and a host of proprietary control protocols. You have to know what
the control interface on these amps is, or you will be in trouble.
