General Mach Discussion / simple AC servo speed control?

« on: August 29, 2008, 01:47:03 PM »

Hello to all

I'm pretty new to this, so please bear with me!

I have a nice sized AC Servo motor that I would like to use to drive a grinding spindle.

The label says 200 volts and 200 watts.

There are 4 wires coming from the motor. I'm not planning on using the encoder.

I thought I read on another forum, where it's possible to drive this motor with a "Flux Vector" VFD.

Has anyone tried this approach?

Thanks for your input!

General Mach Discussion / 5 phase stepper and Mach 3

« on: February 26, 2008, 12:57:30 PM »

Hi Guys

I'm a newbie to the world of Mach 3, so I'm excited to get started!

I have a pretty simple application: I want to use a 5 phase stepper and Vexta driver to turn a ball-screw driven linear slide.

What is the smallest step I'll be able to move? (degrees of rotation)

Any advice?
