: High current / abnormal current on the L-Axis (Typically the X-axis).
Verify the automated lube pump is cycling and oil pressure reaches the Z-axis splitters.
A systematic "repack" of the system involves these critical diagnostic steps:
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). fanuc 414 servo alarm z axis detect error repack
Simultaneously, check the servo amplifier itself. The amplifier's LED display shows a numeric code that corresponds to the diagnostic bits. Common codes include:
: The issue is likely a short circuit in the motor or power cables .
Inspect the pulse coder (encoder) connection on the rear of the Z-axis motor. : High current / abnormal current on the
Check for mechanical binding or "racking" in the box ways or ball screws. :
