Re: Controlling an AC servo as a spindle on a lathe - wiring suggestions

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

Here is the wiring for JMC Servos as spindle drive.

That is helpful. Looks pretty similar.

Re: Controlling an AC servo as a spindle on a lathe - wiring suggestions

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.

Controlling an AC servo as a spindle on a lathe - wiring suggestions

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 h...

Re: Controlling Lathe turret as axis with stepper and no encoder

Thanks for the helps, guys. I am a bit unclear on the concept of setting the gear ratio to be one tool increment. Let's say, hypothetically speaking, my motor requires 400 steps to to make one revolution of its OWN axis and is connected to the turret via a 4:1 gear ratio.The turret has 8 tools, spac...

Controlling Lathe turret as axis with stepper and no encoder

Hi guys. So I have an 8-tool turret on an old Rhino ST8 lathe that I am trying to drive as an A axis on the lathe. I have modified it to be spun by a stepper motor and there is a pneumatic cylinder that locks the turret in position when the desired position is achieved. I have a home switch that ali...

Re: CNC12 Lathe Error 913 Can't open gcode file

You are exactly right! Thank you!
I have no idea why that is. On my mill, I always open the NC files directly from my USB drive and I have never seen this error. Now I have to always copy my files from my usb drive to that folder. Quite annoying. At least it works now though. Thank you again.
