Hey bro! I am sorry to see that no one had responded to your inquire, I wonder what was the cause of the problem? and if you have solved? I am facing very much the exact same scenario over here. New to this type on control, mostly Fanuc. Machine seems to be out of wack, the spindle drive is not receiving the ENABLE signal from I guess the I/O card or who knows... Most of machine operations are working. just the dam spindle not going. Hope you can help! peace!
