I have a Tornos ENC-74, with a Fanuc 0tt control. I turned it on tonight to start a new set-up, and I'm getting a PS/90 alarm during zero return (head 1, X-axis). I've tried resetting the cooridinate system (G,P,& Can) - no help. The proximity switch appears to be working and the control is getting the signal (dgn 0.0 changes from 0 to 1 when switch lights). This happened about 3 months ago, and I turned it off and on again about 4 times and it cleared. It won't clear tonight.
Anybody have any thoughts/solutions?
Matt
