Analog Input Low Fault

What does 50 mean?

One or more analog input signals are below 50% of their minimum signal range. This suggests a defective or loose control cable, or a malfunction in the signal source itself. This can lead to incorrect control inputs and affect drive operation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the functionality of the analog signal source to ensure it is outputting the correct signal.

2. 4

   Ensure the parameter 'AI1 Signal Range' (and others if applicable) is set correctly for the expected input signal range.

3. 5

   Replace any defective parts found, such as cables or sensors.
