Hi There,
I am tryin to pick a servo drive to xyz some servos on an older CNC knee mill I plan to retrofit with a Centroid Acorn control. I was curious if any of you have experience with these drives and would recommend or not recommend them? I am also very open to any other options that you would recommend. The servos are 63Vdc, 3.75 amps, .25hp rated servos. I realize these servos are a little underpowered for the fairly beefy robotool they are on, but I was happy enough with their performance before the old control died, so they should continue to be ok.

I admittedly do not know a whole lot about servo drives and am curious if these drives have pros/cons I should know about, or if there is some significantly better alternative.

The servos have these encoders on them currently.

I do have a few CUI AMT113Q-V encoders I picked up from an odd job my work did one time and were going to throw away. I could switch out the original encoders if needed to get better performance too.
