Fanuc 414 Servo Alarm Z Axis Detect Error -

The pulse coder mounted on the back of the FANUC servo motor tracks rotation. If internal optical disks become contaminated with oil, or if the internal circuitry overheats and degrades, the encoder will output corrupt data or stop communicating entirely. 3. Servo Amplifier Hardware Faults

Servo amplifiers overheat when electrical cabinet fans or filters are clogged with oil mist and dust. Overheating accelerates internal component failure. fanuc 414 servo alarm z axis detect error

What are the values of on your screen?

Check the cable independently. Any reading below 10 Megohms indicates a breakdown in insulation, meaning the cable or motor must be replaced or rewound. 4. Swap Axis Cables (Isolate the Amplifier vs. Motor) The exact diagnostic numbers depend on your system:
