Hi guys.
I am trying to wire up an AC servo drive to control a servo as my spindle drive on a Rhino 8 lathe. It's a 3.8kW servo. The driver takes a -10 to 10V analog signal. The Acorn only outputs 0-10V. Is there another way to control it? It can obviously take step and direciton, I just dont know how to configure the software to control the spindle with that signal. I am also using the 3rd axis outputs to control a stepper motor on a turret.
Any suggestions are appreciated.

Depends on the driver.

I use 0-10V for speed and the Dir Input on the driver to change direction.

The driver only takes -10 to 10V input if it's controlled with analog signal. The step and direction signals are used if that mode of control is used/enabled.

pls post the manual.

Here is the wiring for JMC Servos as spindle drive.

I have attached the manual. Hopefully it opens up.

That is helpful. Looks pretty similar.

SigIn6 should work to change direction

Check out CNC4PC's C89 adapter board to convert analog signal to -10/+10

Thank you for that suggestion. I will definitely give it a try, I didn't know that existed.
