Automatic Restart Monitoring Timeout

What does F07320 mean?

This fault occurs if the drive fails to successfully restart after the automatic restart monitoring time (p1213) has expired, even after multiple attempts. It can also be triggered if p1213 is set too low relative to other critical timing parameters like p1212, p0346, or flying restart delays, preventing successful motor start-up. The system attempts automatic acknowledgements, but persistent issues or incorrect parameter settings prevent successful restarts, potentially leading to prolonged downtime.

Complete Troubleshooting Guide

1. 1

   Acknowledge all present faults and withdraw the power-on command to re-activate the automatic restart function.

2. 2

   Increase the automatic restart monitoring time (p1213) if faults are not immediately and successfully acknowledged.

3. 3

   Verify that p1213 is set higher than the sum of p1212, the magnetizing time p0346, and any additional delay time due to flying restart.

4. 4

   If p1210 = 1, ensure p1213 is not set lower than p1212.

5. 5

   For specific p1210 modes (14, 16, 26), ensure faults are manually acknowledged or the switch-on command issued within the time defined in p1213[0].
