Cause: Measurement circuit ADC comes when problem with measurement circuit of power unit (analog to digital converter).
A5ED warning in ABB ACS880 drive indicates Measurement circuit ADC. This means the drive's internal circuitry that measures the ADC voltage on the main power bus is not functioning correctly.
Solution:
