Rutex Servo issues.

[ty1295]

Still working my way up the learning curve.

Got Rutex drives with DC Servo motors.

Can run the rutex tuning software (windows version thanks to art) and get the input from pot settings.

If I increase Kd any motor starts spinning. Adding Kp doesn't help any.

Tryed switching power leads, didn't help.

When I load Mach2 I can actually make motor move, stop etc. But going in one direction it likes to fault. Moving the other direction does not cause problems. (This is with Kp, Kd, Ki all at zero)

Slowed velocity, tried slow feed rates, same thing.

Going to triple check encoder wiring today.

Am I missing something?

seeing i just ordered my controllers really can't be much help

but did you check out the old posts on rutex forum like this one

maybe one about from ynneb . they might have fixed the label problem allready but they give some sample ki/kd/kp settings to start off with.

Gentlemen,

If you are having problems setting up Rutex drives, please give me a call at 573 341 1528. If I don't have the answer, I will get the answer for you. I ship the Rutex products to USA customers, and provide limited phone support. I have to admit that I don't visit this forum regularly. I have a number of years of experience building CNC equipment, and my favorite drives are the Rutex drives. This is why I do USA distribution for Rutex. I also use them in lathe control systems I have sold for the last three years. You should not have trouble setting up the Rutex drives.

May need to look at encoder signals with a scope. Sometimes the encoder is not correctly quadrature. You also may have blown output mosfets in one direction only.
