Fanuc 414 Servo Alarm Z Axis Detect Error Jun 2026

from Z-motor to servo amp:

Imagine you are halfway through a critical three-hour machining cycle on your vertical machining center (VMC). The spindle is whirring, coolant is flowing, and then—silence. Your Fanuc-controlled CNC machine halts. On the bright red CRT screen, a message glares back at you: fanuc 414 servo alarm z axis detect error

= “Servo Alarm: Z-axis – Detect Error.” This means the CNC control unit commanded the Z-axis motor to move, but the Position Coder (pulse coder) or the servo system failed to return a valid feedback signal within the expected parameters. It’s essentially a “loss of control” alarm. coolant is flowing
