Spindle Supplementary Temperature Fault

What does F07018 mean?

This fault is issued immediately if the actual spindle temperature (r4105) exceeds the fault threshold p4102[1]. Alternatively, if the alarm threshold p4102[0] is exceeded and the delay time set in p4103 expires without the temperature falling below the alarm threshold, this fault is also triggered. The fault requires acknowledgment and clears only when the temperature falls below the fault threshold, considering a fixed 2 K hysteresis.

Complete Troubleshooting Guide

1. 1

   Acknowledge the fault at the drive control unit.

2. 2

   Check the actual spindle temperature (r4105) and compare it against both the alarm threshold (p4102[0]) and the fault threshold (p4102[1]).

3. 3

   Inspect the spindle cooling system, motor load, and mechanical components for any issues causing excessive heat generation.

4. 4

   Verify the operation and wiring of the temperature sensor connected at terminals X522.7(+) and X522.8(-).

5. 5

   Review the delay time set in p4103; adjust it if it's too short for normal temperature fluctuations, but ensure safety.
