PID Feedback Loss (Wire Break)

What does FDBKL mean?

The analog input programmed for PID feedback has risen above 21 mA or fallen below 3 mA, indicating a loss or out-of-range signal. This fault is effective only when b5-12 (Feedback Loss 4 to 20 mA Detection Selection) is set to 2 (fault).

• PID feedback source is not installed or not working properly.
• Analog input signal for PID feedback has risen above 21 mA or fallen below 3 mA.

Click steps to track your progress.

1. 1

   Confirm that the PID feedback source is installed and functioning correctly.

2. 2

   Adjust drive response to this condition using b5-12 (Feedback Loss 4 to 20 mA Detection Selection) and b5-13 (Feedback Loss Go To Frequency).

3. 3

   Control auto-restart of this fault using L5-42 (Feedback Loss Fault Retry Selection).
