This is on an older series 2 Bridgeport. It had a Centroid control on it when I bought. We re-did it with a Camsoft pc based control.

I am changing my stepper drives and the new drives (Automation Direct SureStep) have a lot of parameters I am not familiar with.

The mounts are about 3 1/2 c/c. Any idea what these might be or where to find specs? There is no nameplate on them.

Thanks!

Are you certain they're steppers? Looks like an encoder or perhaps resolver on the end, making me wonder if it's a servo motor, especially being round, though I guess a stepper can have an encoder as well.

I've got Automation Direct Surestep drives on my BP Series I running the original nema 42 step motors quite successfully. I pretty well guessed at some of the parameters; I found once I got enough power supply voltage and current into the drive, most of the settings didn't make any apparent difference.
