Fanuc 414 Servo Alarm Z Axis Detect Error Repack

The is a critical CNC system fault indicating that the digital servo system has flagged an abnormality on the Z-axis control loop . It forces the CNC machine into an immediate Emergency Stop state to protect the hardware.

is one of the most common, yet critical, faults encountered on CNC machines. When the screen displays "414 Servo Alarm: Z-Axis Detect Error" (or similar axis-specific messages like Y-Axis, X-Axis), it indicates that the Fanuc servo amplifier has detected an abnormal condition in the or servo drive circuit . fanuc 414 servo alarm z axis detect error repack

The 414 alarm often acts like a "Check Engine" light. While the screen displays "414," the real clues are hidden on the in the electrical cabinet. For the Z-axis, you will typically find a sub-alarm like 8, 9, or A , indicating an overcurrent or short circuit in that specific drive channel. The Troubleshooting Journey

: Bit #6 (OFS) indicates an A/D converter issue. The is a critical CNC system fault indicating

If you have access to an identical axis (such as a dual-axis servo amplifier with both X and Z channels):

. For example, a "1" in the OVC (Overcurrent) bit confirms a high-current condition. Amplifier Display: When the screen displays "414 Servo Alarm: Z-Axis

: High Current Alarm. Indicates a short circuit or an extreme current spike in the amplifier power module.
