we have older IKEGAI lathe with Fanuc 18T controls. During cutting lathe stoped and we can't figure out why. We checked overtravel switches even moved machine manually over - nothing. Any ideas??
-EMG- in flashing on the screen and alarm light is on.
You will need to refer to machine builder's(NOT Fanuc manual) electrical wiring diagram and see what else is tied to Emergency stop circuit. I have seen anything from lube pump overload to air pressure low tied to EMG circuit.
