Cause : BU voltage difference comes when main voltage difference detected by the branching unit. This happens when the DC link voltage between the main drive unit and the branching unit (if you're using one) differs beyond the acceptable limits.
An AE0C fault code in your ABB ACS880 drive indicates a branching unit DC link voltage difference.
- Check AC fuses.
- Check supply cable.
