Cause : AI Supervision comes when an analog signal is outside the limits specified for the analog input.

The fault code 80A0 in your ABB ACS880 drive indicates an AI supervision fault. This signifies an issue with an analog input signal exceeding its permissible limits.

  1. Check the auxiliary code (format XXXX XYZZ). “Y” specifies the location of the input (0: Control unit, 1: I/O extension module 1, 2: I/O extension module 2, 3: I/O extension module 3). “ZZ” specifies the limit (01: AI1 under minimum, 02: AI1 above maximum
  2. Check signal level at the analog input.
  3. Check the wiring connected to the input.
  4. Check the minimum and maximum limits of the input in parameter group 12 Standard AI.
