Turn off the machine, shut off the main factory breaker for 2 minutes, and power it back on. This fully drains residual power from the capacitors.

If the previous steps fail, it's time to access the FANUC . This is a pre-operating system environment that loads even if the main CNC software is corrupted. It's your best friend for data recovery. Accessing the Boot System typically involves holding down two specific keys (e.g., 6 and 7 on the MDI panel for many models, or the two rightmost soft keys for an 0i series) while turning on the CNC power. When the system stops progressing past the "starting

To isolate and resolve the issue safely, execute the following troubleshooting steps in sequence. 1. Perform a Hard Power Cycle
