PID Feedback Loss (Low)

¿Qué significa FbL ?

The analog input programmed for PID feedback has fallen below 3 mA. This occurs when the PI feedback source is incorrectly installed, not working, or has a wiring issue (wire break). The drive's response to this condition is controlled by parameters b5-12 and b5-13.

• PI feedback source is incorrectly installed or not working
• Analog input programmed for PID feedback has fallen below 3 mA
• Wiring issue (wire break) in the PID feedback circuit

1. 1

   Confirm that the PID feedback source is installed and working properly

2. 2

   Verify the analog input signal for PID feedback is within the expected 3-21 mA range

3. 3

   Check drive parameters b5-12 (Feedback Loss 4 to 20 mA Detection Selection) and b5-13 (Feedback Loss Go To Frequency) for drive response settings
