PID Feedback below min. Value

What does F00221 mean?

The feedback signal for the PID controller has dropped below its configured minimum threshold (p2268). This indicates an issue with the feedback sensor, its wiring, or an incorrect parameter setting, causing the PID loop to lose its reference and potentially leading to unstable control or undershoot.

Complete Troubleshooting Guide

1. 1

   Verify the operation and wiring of the PID feedback sensor for damage or disconnection.

2. 2

   Adjust parameter p2268 to an appropriate minimum value, considering the application's operating range.

3. 3

   Review and adjust the PID feedback gain if the signal appears noisy or inconsistent, or if the sensor range is incorrect.
