101

PID Feedback Supervision Fault (PID1)

Vacon · 100 FLOW Application

What does 101 mean?

The feedback value for PID controller 1 is outside the configured supervision limits (P3.13.6.2 and P3.13.6.3) for a specified delay (P3.13.6.4). This indicates a deviation from the expected process variable feedback, suggesting an issue with the process or the sensor. It can lead to incorrect control actions and process instability.

Complete Troubleshooting Guide

  1. 1

    Investigate the process being controlled for any anomalies or deviations in the feedback loop.

  2. 2

    Check the PID controller parameter settings, specifically the supervision limits (P3.13.6.2, P3.13.6.3) and the delay (P3.13.6.4) for correctness.

  3. 3

    Verify the integrity and calibration of the feedback sensor connected to PID1.
