My controller was set-up with a 72 Vot AC transfomer for the servo power, this gives you 100 Volts DC at the Servo Card Rectifiers. That should give some info on what you will need for Geko drives.

Bob,

If your servo amps are in good condition, you really ought to keep
them. The Servo Dynamics
are good amps. I have an interface to this type of amplifier, and EMC
has drivers for
it. Some info on my interface is at
