Cause : No motor data comes when the drive is not receiving the necessary motor data required for proper operation or parameters in group 99 have not been set.

The fault code "A6A5" in your ABB ACS880 drive indicates a  "No motor data" warning. This is not a critical fault that immediately trips the drive, but it signifies a missing or incomplete configuration for the motor connected to the drive.

• Check that all the required parameters in group 99 have been set.
