Ensure the Z-axis brake is releasing fully, or it will create a massive overload/error state. Conclusion fanuc 414 servo alarm z axis detect error repack
Because the Z-axis travels vertically, the servo motor features an internal electromagnetic spring-set holding brake to keep the head from crashing when power is cut.
If the alarm occurred after maintaining or "repacking" (greasing) the Z-axis motor, improper reassembly is likely the cause. For expert advice on repairing or replacing your
A on the Z-axis indicates a detection-related error in the digital servo system, typically triggered when the CNC detects abnormal current flow in the servo amplifier . Because the Z-axis often carries the weight of the spindle head, this alarm frequently signals that the motor is fighting gravity or mechanical resistance. Core Causes for Z-Axis 414 Alarms
: High current or short-to-ground anomalies on the N-Axis (Typically assigned to the Z-axis or auxiliary axes). 2. Root Causes of the Z-Axis Detection Error Conclusion Because the Z-axis travels vertically, the servo
This article provides a comprehensive overview of what this alarm means, its common causes, and a systematic, step-by-step approach to troubleshooting and fixing it, particularly in high-strain "repack" environments. What is a FANUC 414 Servo Alarm?
