| Mistake | Consequence | |---------|-------------| | Not marking coupling position | Loss of Z zero position, crash risk | | Touching encoder disk | Permanent damage (finger oils) | | Over-torquing encoder screws | Disk cracking, eccentric rotation | | Forgetting 1815#4 reset | 417/427 alarms after repack |

Do not repack until you fully verify cables and swap-tested the motor.
80% of “detect error” alarms are cable/connector problems, not internal motor failure. fanuc 414 servo alarm z axis detect error repack

If you have additional alarm numbers (like 414 + 424, or 414 + 434) – those suggest multiple axes → look at power supply or fiber optic cable (FANUC serial servo bus). | Mistake | Consequence | |---------|-------------| | Not

To pinpoint the exact internal failure, check the following diagnostic bits on the CNC screen: Diagnostic No. 200 : Check bits for specific errors: Bit #7 (OVL) : Overload condition. Bit #6 (LV) : Low voltage in the servo amplifier. Bit #5 (OVC) : Overcurrent detected by digital servo software. Bit #4 (HCA) : Abnormal current (High Current Alarm) in the amplifier. Bit #2 (DCA) : Regenerative discharge circuit alarm. Bit #1 (FBA) : Feedback cable disconnection. Diagnostic No. 204

: 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).

: High current on the 3rd axis (N)—this is often the Z-axis in 3-axis systems. 3. Probable Causes Fanuc 414 Servo Alarm Z Axis CNC Vertical machine
