80% of “detect error” alarms are cable/connector problems, not internal motor failure.

By following the steps outlined in this article, you should be able to troubleshoot and resolve the Fanuc 414 servo alarm on the Z-axis, getting your CNC machine back to optimal performance. on the Z-axis is the start of a classic detective story

This is a that triggers when the CNC’s position deviation (the difference between where the Z-axis should be and where it actually is) exceeds a preset limit. In simple terms:

After repacking:

| Alarm Code | Axis Affected | Description | |------------|---------------|-------------| | 414 | X axis | X-axis digital servo system error | | 424 | Y axis | Y-axis digital servo system error | | 434 | Z axis | Z-axis digital servo system error |
