Fanuc alarm
A servo parameter for one axis is set to a value the control won't accept.
A servo parameter for one axis is set to a value the control won't accept. This often shows up after a battery loss, a parameter restore from the wrong file, or a motor or amplifier swap.
Lock out the machine before reaching into it. Never bypass a door switch or interlock to clear an alarm.
Call a Fanuc tech if you don't have a good backup or a motor was just replaced. They can set the motor ID and reload servo parameters safely.

A servo parameter for one axis is set to a value the control won't accept. This often shows up after a battery loss, a parameter restore from the wrong file, or a motor or amplifier swap.
Parameters lost or corrupted after the memory battery died. Wrong parameter file loaded. Replacement motor with a different motor ID. Someone edited a servo parameter.
Note which axis is named. Check the diagnostic page (around 280 on many controls) that shows which parameter is wrong. Find your last good parameter backup. Don't guess at values. Servo parameters wrong by one digit can make an axis run away. Call a Fanuc tech if you don't have a good backup or a motor was just replaced. They can set the motor ID and reload servo parameters safely.
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.
