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.
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 or a repair job, please call 800-691-8511 or email sales@mroelectric.com.

я как сервисник работаю с оборудованием нескольких поставщиков, так вот я не могу помнить/знать все ошибки новых станков, находящихся на гарантии или опставленных 5 лет назад.
1. я могу попытаться перевести сообщение об ошибке/ почитать мануал по ней
2. посмотреть логику ее формирования в станке (номера от 1000 до 2999)
3. почитать yellowbook на русском/английском
4. решать вопросы на основании опыта, схем, документации и логики
смысла валить в кучу описание ошибок каждого конкретного станка нету… надо просто знать общий принцип…
если электронщик сутки искал проблему — то:
0. квалификация электронщика
1. это не его станок (станок на гарантии, станок другого цеха и т.д.)
2. схемы не соотвествуют документации и сервисники поставщика не отвечают оперативно.
3. оператор сказал о проблеме простоя станка с утра только к концу смены
4. и т.д.
