I have Fanuc 10m control on a 1987 VMC I get the same servo overload signal occasionally. (If the spindle stalls and it keeps feeding or when doing small linear moves while machining small part contours)
I turn off the control as well as the power switch on the back of the machine. I then open up the panel with the servo drives and press a reset button on the drive, then power back up. Sometimes I have to repeat it again but its worked for me. I don't know if this is your problem but it may be worth looking into. |
