Fanuc CNC Alarm List

 

This FANUC alarm code list should help you properly diagnose your CNC error message. 

What is a FANUC Alarm Code?

A FANUC alarm code, also called a FANUC fault or error code, is how a CNC control indicates there is a problem. This error message could indicate issues with either the machine itself, be that electric or mechanical. The FANUC error code might also indicate an issue with the g-code program. 

How to Diagnose Your FANUC Alarm Code

Use the list below to interpret what exactly the fault code is trying to communicate. If you require a replacement part, know that MRO Electric stocks thousands of FANUC CNC replacements. Get your new FANUC servo amplifier or check out our FANUC servo motors. To order a replacement part please email paycnc@paycnc.com.

These FANUC Alarms are valid for following FANUC Controls:

• 0i Model A
• 0i/0iMate Model B
• 16/18 Model PB
• 16/18 Model C
• 16i/18i Model A
