I am retrofitting a Lathe with EMC. 30 Hp Reliance DC motor and spindle drive. My problem is following errors on the spindle joint......If I try to spin the axis by hand with EMC in the run state I get a following error and I attribute it to EMC seeing movement when there is none called out or requested. The second case is when I actually call for spindle movement I get a following error before the spindle gets up to speed. The spindle starts but the following error shuts everything off pretty fast. Any Ideas?

The spindle is normally not a motion axis so following error should not even apply to spindle motion. Can you post yout HAL and INI files?

I see I do have it as a motion axis. I do believe that was created through PNCconfig but it was so long ago that I have forgotten that part. I am starting to make major progress but the problems seem to be getting bigger....LOL
Thanks

What are my choices of signals except the motion signals? should I be connected to the manual signals?

This is rather odd.
Which axis shows a following error?
Is it possible that the resolver numbers are mixed up? Can you check in machine->show hal config ("Watch" tab, the other tab isn't updated live) that moving the spindle changes the value of resolver.00, and that X and Z are on Resolver.01 and 02 ?
You are one of the very first users of the Resolver driver, so it is possible that there might be a mix-up inside the code.

My spindle is fine........I was getting feed back on my x axis that was actually my joint error. I was hasty with the error.....because every time I touched the spindle I got the following error. I am goung to move the x axis away from the spindle on the resolver board. Thanks for the help today.
