An axis hit its physical overtravel limit switch. The machine went past its soft limits and tripped the switch at the end of travel.
Reference position lost or soft limits changed. Limit switch or its dog damaged, loose or full of chips. Coolant in the limit switch. Crash.
Use the overtravel release button (if your machine has one) and jog off the switch in the opposite direction. Look at the switch and its trip dog for damage or chips. Find out why the soft limit didn't stop it first. Call a tech if the switch is damaged, the alarm won't clear, or the axis went past its soft limits for no clear reason.
Alarm numbers and text can differ by control model, software version and machine builder. This page is a starting point from people who have worked on these machines, not a replacement for your machine builder's manual.
