Fanuc Alarm Codes
Type the alarm number from your screen. See what it means, what to check first, and who near you can fix it. Written by people who have chased these alarms on the shop floor.
We don't have that alarm yet. Send it to us with your machine make and model, and we'll pass it to a tech who works on your control.
Safety first: lock out the machine before reaching into it, and never bypass an interlock to clear an alarm. Alarm numbers and text can vary by control version and machine builder, so check your machine manual too.
