Z axis over travel alarm

[jhuddleston]

I over traveled my Z axis this morning with the jog which ordinarily should be no problem. I tried to clear the overtravel by pushing the machine ready button and alarm release button moved the z to the middle of travel and tried to reset alarm. The machine still says over travel. I tried to redraft the machine with cancel P as well as trying to reference return with no avail. Does anyone have any suggestions. Fanuc 18
