Fanuc 414 Servo Alarm Z Axis Detect Error Repack !!exclusive!!

Look for bits set to 1 . Common issues include:

If the alarm occurred after maintaining or "repacking" (greasing) the Z-axis motor, improper reassembly is likely the cause.

Resolving a "Z-Axis Detect Error" requires a methodical process of elimination across both hardware components and physical connections. In many shop environments, "repacking" refers to the process of tearing down, cleaning, inspecting, re-insulating, and resealing contaminated cables, connectors, or motor housings to clear internal short circuits. 1.

While many 414 alarms can be resolved through systematic troubleshooting, certain conditions require professional intervention:

When operating FANUC-controlled machinery, encountering a can cause significant, immediate downtime. This alarm is often associated with "repack" or heavy-duty Z-axis applications, where the vertical axis is subjected to high loads, frequent reversals, or rapid acceleration/deceleration. Look for bits set to 1

The Fanuc 414 servo alarm can be triggered by several factors, including:

On your Fanuc control, navigate to the screen and check No. 200 or No. 204 . Diagnose a Fanuc High Current Alarm in 10-Steps In many shop environments, "repacking" refers to the

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.

The diagnostic registers provide the specific fault bit that triggered the alarm. For Z-axis faults, the relevant registers are:

Based on decades of field repair experience and documented case studies, 414 alarms can be categorized into the following root causes:
