"FFdA" Fan Feedback warning in a Schneider ATV950 drive indicates an issue with the feedback from the cooling fan. This warning typically suggests that the drive is not receiving the expected feedback signal from the fan, which may affect the cooling efficiency of the drive.
Here are the steps to address the FFdA warning:
-
Inspect the Fan: Visually inspect the cooling fan for any signs of damage or obstruction. Ensure the fan blades can move freely without any hindrance.
-
Check Fan Operation: Verify that the fan is running when the drive is in operation. If the fan is not operating, it may need to be replaced.
-
Inspect Feedback Connection: Check the wiring and connections related to the fan feedback signal. Ensure there are no loose or damaged wires, and all connections are secure.
-
Clean the Fan and Vents: Dust and debris can accumulate over time, reducing the fan's efficiency. Clean the fan and ventilation openings using compressed air or a soft brush.
-
Fan Replacement: If the fan is faulty or not providing the correct feedback signal, it will need to be replaced. Refer to the ATV950 drive's manual for instructions on how to replace the cooling fan.
-
Reset the Fan Counter: After inspecting, cleaning, or replacing the fan, you may need to reset the fan counter in the drive's settings. Consult the drive's user manual for instructions on how to reset the fan counter.
