Fanuc 414 Servo Alarm Z Axis Detect Error Repack ((exclusive))

Do not swap parts blindly. Fanuc controls record internal error bits that pinpoint the exact sub-circuit causing the 414 alarm. Press the key on your Fanuc MDI panel. Select the DIAGN (Diagnostic) softkey. Type 200 and press INPUT (or check number 204 ). Diagnostic 200 Bit Mapping

Today, "repack" has evolved to mean:

Troubleshooting and Repack Procedure for Fanuc Servo Alarm 414 (Z-Axis) Alarm Code: SV0414 (Series 16i/18i/21i/0i) or APC 414 (Series 0/10/11/12/15) Symptom: Digital servo system error; Z-axis movement prevented. Do not swap parts blindly

At this point, many shops would call for a ballscrew replacement ($5k–$10k + weeks of lead time). But there is a : Repacking . Select the DIAGN (Diagnostic) softkey

On a FANUC control screen, the explicitly flags a digital servo system abnormal condition. When it specifies the Z-axis , the system tells you that the feedback and power looping for the vertical axis has been compromised.

Signals internal communication errors or link errors between the CNC control board and the amplifier module.
