If the cable is good, swap the motor encoder (pulse coder).
If the alarm persists even with the motor leads disconnected, the or its internal Intelligent Power Module (IPM) is likely faulty and requires replacement or repair. fanuc 414 servo alarm z axis detect error repack
Before tearing down mechanical assemblies, execute this systematic isolation protocol to determine exactly where the fault lies. If the cable is good, swap the motor encoder (pulse coder)
: Check for auxiliary errors like current conversion issues (OFS) or feedback pulse errors (PMS). 2. Check Hardware Indicators Inspect the physical Servo Amplifier Module (SVM) in the electrical cabinet. A often corresponds to an LED display of 8, 9, or A on the amplifier: TIE Industrial Fanucworld : High current on the 1st axis (L). : High current on the 2nd axis (M). If the cable is good
