Today my PCNC1100 started to slow down and speed up maybe 300 to 500 rpms. So I thought I would check the VDR and it showed 56.5. I then check the manual and it said it should be at 137.0 at 500rpms. So I went to the Cal. info. in the manual. Did that and now NO spindle speed. I can manually start and stop the spindle. What did I do wrong?. Now went I try to do it I get a message that says Magic number invalid.
Thanks
