Schaublin 125-CNC retrofit.

Good point. Those huge cast aluminum motor housings might have a data plate underneath. I didn't think to look. Or those are just huge motor covers, and the motors are inside Overkill was a thing with this lathe.

@Anfänger

if you need some information, just ask ... my wife got all type plates re-readable

@db1981 Thanks, but I guess I have figured everything out which stays and the rest I switched to something new, where I know the parameters. But do you have a thread or pictures somewhere? I would love to see your machine.

Is there a technical reason to prefer setp/dir vs analog control when driving AC servos?

If I switch to modern AC servos which support either step/dir or +/-10V analog control input, and add linear encoder feed back, I have the choice between the Mesa 7i95 or the 7i97. What are the advantages / disavantages of one over the other?

Actually, if I find AC servo sets which pass their encoder signal back to the controller, I could do closed loop back to LinuxCNC and not have the headache of finding a space to mount a cross slide linear encoder.

I don’t know, but I prefer +-10V analog control.
The reason is: I have already done it with the Sinumerik
The lichuan servos and drives I use pass an encoder signal to the control and can be driven step/Dir and +-10V Most prefer Step/Dir to avoid tuning, but I found it not to hard (But the drivers were already tuned) I will see later if I regret it. And you can tune without the servos actual attached to the machine.

I already used analog on the Maho, and had to tune the servos and after a bit of dicking around found a set up which seems fine. I am a big overwhelmed with all the different options right now, but appreciate the inputs.
