Fanuc 414 Servo Alarm on the Z-axis is a high-current detection error occurring in the digital servo system
The "detection error" portion of the alarm usually stems from one of three root categories: the Encoder (the sensor), the Drive System (the mechanics), or the Electrical Signal path. fanuc 414 servo alarm z axis detect error
: Binding in the Z-axis ball screw, lack of lubrication, or mechanical obstruction causing the motor to draw excessive current to compensate Global Electronic Services Feedback Issues Fanuc 414 Servo Alarm on the Z-axis is
Based on real-world case studies and technical guides, the alarm typically stems from one of four sources: the Drive System (the mechanics)
indicates high current on the first (L), second (M), or third (N) axis respectively Diagnostic Screen : On the CNC, view Diagnostic 200
