Servo Alarm Z Axis Detect Error - Fanuc 414

The on the Z-axis is a critical system error indicating that the CNC has detected an abnormality in the digital servo system, most commonly a high current or "detect" error originating from the servo amplifier. This alarm acts as a safeguard, cutting power to the servo motor to prevent catastrophic electrical damage to the drive or motor. Understanding the Root Causes

Do simply reset the alarm and re-home. You must isolate the cause. The on the Z-axis is a critical system

A: Not directly. A low battery causes separate absolute position loss alarms (300, 310). However, if you cleared battery alarms and didn't reset absolute zero, the Z-axis may overtravel and trigger a 414 during reference return. Do simply reset the alarm and re-home

For issues related to the encoder or other feedback devices, perform tests to verify they are operating correctly and providing accurate feedback.
