You have AC Servos.
Maybe cncsnw will confirm the drives are compatible with Oak. I'd stick with them

Thank you Marty.

I saw that after I uploaded the pics and was looking at them a little closer. I am hoping to be able to reuse a lot of it as it was working until the drives started acting up.

Those are Yaskawa Sigma I drives and motors.

If they were in good working order, then they would be plug and play with an Oak board.

If the servo drives are not running reliably, you might consider new Yaskawa servos in their place. 450W motors and 500W drives are not that expensive, and it is likely that new motors of the same rating (e.g. SGM7G-05A7D6S) would install with no mechanical modifications.

Thank you! I'll start doing research in that direction. The X axis drive is questionable. The Z axis is solid. I appreciate your time and input!

You can probably find a used drive of that model on eBay, if needed.

See if you can figure out what's going on. Even if you had to source another Drive, I think you are ahead keeping the Yaskawa, Drives/Motors and go with Centroid Oak and their cables.

Maybe you can explain what the drive is or isn't doing. What is the history on the machine?

Thanks Marc for chiming in.
