MCG Server Controller for 4th axis

The Leadshine DCS810 is a brush-motor servo drive, essentially similar to the MCG servo amp you already have. It ALSO needs a controller, which it is NOT.
What I THINK you are trying to do is create a standalone positioning control for the rotary table. Is that right? Or, do you want to integrate the rotary table into some other CNC system?
If you have some system that produces step/direction pulses, then you need a step to servo drive. Assuming the motor is indeed a brush motor, then the Gecko 320X is likely the best way to go.

The idea is to use it as a 4th Axis in a CNC mill. The machine already has closed loop stepper drives for x, y and z controlled via a Mesa 7i96s.

The servo motor is most likely brushed based on similar motors I've seen for sale.

So if I understand this correctly, wiring the MCG servo amp directly to the 7i96s control the motor wont work (I'm using the analog pins for the spindle currently). I need to have an intermediary device such as the Gecko 320X to convert the signals? or would it be easier to just get a DCS810 and use it directly with step/dir wiring to the 7i96 ? Or is it likely that this motor doesn't do step/ dir, only analog ?

Sorry I don;t have a ton of experience with servos.

Yes, I am pretty sure you are right, the Mesa board probably will send step/direction to a motor drive, and the MCG drive wants analog.  But, a Gecko 320X will do what you want.  steps in -- brush motor out.
