Fanuc 414 Servo Alarm Z Axis Detect Error -

The most common cause of a detection error is a failure in the feedback loop. The servo motor is equipped with an encoder (a pulse coder) that reports the rotor's position back to the main board.

Check the pulse coder cable (feedback cable). Ensure it is shielded and not running too close to high-voltage lines, which can cause electrical noise interference. 📋 Step-by-Step Troubleshooting Flow fanuc 414 servo alarm z axis detect error
