Fanuc 414 Servo Alarm Z Axis Detect Error Better Info

= “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.

: If the motor brake does not release properly (24V DC not reaching the coil), the motor will pull excessive current trying to move, triggering the alarm. Shorted Motor or Cable fanuc 414 servo alarm z axis detect error

Internal hardware failure, such as a burned-out IGBT or a faulty axis control card, can cause the drive to "misread" the current even if the motor is fine. = “Servo Alarm: Z-axis – Detect Error

This alarm typically presents as a sudden stop in the motor while operating or immediately upon powering on. Shorted Motor or Cable Internal hardware failure, such
