The following post breaks down how to diagnose this error and what to look for when inspecting or "repacking" your axis components. Troubleshooting the Fanuc 414 Z-Axis Detect Error
A technician’s diagnostic flow typically looks like this:
The pulse coder (encoder) on the Z-axis motor is malfunctioning.
Fanuc 414 Servo Alarm is a critical system fault indicating a Digital Servo System Abnormal
Several factors can cause the Fanuc 414 servo alarm on the Z-axis. Some of the most common causes include:
Here is a general step-by-step procedure for repacking a Fanuc servo motor:
Based on diagnosis, replace the faulty unit.
The Fanuc 414 alarm is a general protective fault issued by the CNC. The control stops the machine because it senses abnormal behavior in the servo circuit. When analyzing the "Z Axis Detect Error," you must pinpoint if the issue is an overload, a physical short, or a communication disconnect. Deciphering the On-Screen Diagnostics
Inspect the power leads (U, V, W) and the encoder cable for coolant damage or frayed insulation.
