Servo drive or some kind of problem

Good news…. So the book for the drivers benb posted isn’t like mine but close enough I kept reading it to see how those drives work. He also mentioned the digital inputs.
So I read back to make sure I didn’t misread what I read about external switches (essentially left/right drive disable).
Turns out I misinterpreted it or whatever but the books says something like this
“If no external interlocks are required wire them to signal common”.
So since I was on the bench I jumped each of them to common on the drive board.
Next section I read how the L/R disable works and it turns out the switches are switched to common to disable the drive in one direction. DOH!

Went straight to the box this am. Pulled my jumpers enabled the drive and I have motion in both directions.

And Tommy you are def correct. I listened this time and only used the 1.5v. Those drives move pretty good with that.


Anyway. Thanks again for everyone’s help. On to the tuning tutorial I suppose

You are welcomed, always.
Did you read the servo tuning and wiring on this forum? Can not recal if i did point to that, but that is a must for such retrofits.

And while you are at it, please let me know if there is something that can be explained better or anything to add or remove.
Also, no skipping steps when wiring stuff, one by one step at a time.
