A 24 tool changer seems to give me repeating decimals. may have to rehome every so often 2500 count quad encoder (10,000) 24 seems to be a bad number for repeating decimals!

The carousel is an air motor. solenoid forward and solenoid reverse. An additional solenoid for high speed rotation on long travel changes. I've got the index pulse near Tool1. I'm wondering if I should be resetting the pulse count on a rollover. I was planning to use the pulses needed from tool to ...

Thanks Mark and all that read and follow,

That will be very helpful As I try to plan this ATC program that now will read the 5th encoder channel instead of a tool counter.

Anyone have a PLC I can compare ideas with that uses a real Quad encoder for ATC positioning?

Thanks,

While we work on the PLC program can we run the machine without the tool changer and hand load the tools? The guys would like to use the machine while I work on atc problems as we go?

I'd think that would be simple to do but, not as obvious as it seems it should be?

We hope to rigid tap as well. So the code change I've made wouldn't be suitable for that?

I'll try your code and find the parameter you mentioned. I think I saw it from another ATC post on your website.

Thanks as always Mark

This seemed to work.

Thanks Mark, I'm going to check that out and see what changes we should make. I'm not familiar with Fast Stop. I assumed it is emergency cases as well as, tapping, tool changes? Really would you only want to coast to stop at the end of a program? Seems if used to frequently it could be bad on bearin...

We did resolve this. The owner and I forced on an output setup for fast stopping the spindle and that also worked to enable the drive. The documentation for Siemens just seems complex to find the right information. Late 1990's system. It's labeled PWM but is setup for +10 full forward and -10vdv for...

Does anyone have the PLC code for the ALLINONEDC to do spindle control +10vdc forward and (-)10vdc reverse?

I'm getting the voltage and the enables but, I think I discovered this drive is a PWM. What is the best way to convert or use Centroid to control a PWM spindle servo in your guys experience?
