: Shows 414 SERVO ALARM: Z AXIS DETECT ERR (or SERVO ALARM: Z-V AXIS DEFEKT ERR ).
Insulation breakdown in the motor windings or Z-axis power cables, frequently caused by coolant ingress into connectors. Mechanical Overload:
An electrical short is the most common culprit behind a 414 error. Follow these steps to isolate the fault between the amplifier, cable, and motor: 1. Test the Servo Amplifier (No-Load Test) HELP!! Servo Alarm No. 414: X-axis detect error fanuc 414 servo alarm z axis detect error repack
condition, specifically a detection error related to the Z-axis. This alarm is a "summary" error on the CNC screen, meaning the system has detected a more specific hardware failure within the servo amplifier, motor, or cabling. 1. Understanding the Root Causes
The Fanuc 414 error is an overarching CNC notification stating that a specific axis servo drive software has registered an abnormal electrical condition. It works hand-in-hand with diagnostic parameters on your control screen and physical hardware LED codes on your servo amplifier module (SVM). : Shows 414 SERVO ALARM: Z AXIS DETECT
: Turn off the CNC, keep the main breaker on, and disconnect the motor power leads (U, V, W) from the amplifier.
When your CNC control displays 414 SERVO ALARM: Z AXIS DETECT ERR , the primary computer (CNC) has communicated a fault detected by the physical or Power Supply Module (PSM) . Follow these steps to isolate the fault between
If you have access to an identical axis (such as a dual-axis servo amplifier with both X and Z channels):
is a critical digital servo system fault that occurs when the CNC detects an electrical or operational abnormality, typically related to current, voltage, or feedback, on a specific axis.
