General

The ACS880 drive utilizes BCU-x2 control units. The BCU-x2 consists of a BCON-12
control board (and a BIOC-01 I/O connector board and power supply board) built in a
metal housing.
The supply and inverter units of the ACS880-37 are each controlled by a dedicated
BCU-x2 control unit. The designation of the supply control unit is A51; the inverter control
unit is A41. Both are located in the ACU cubicle (see the drawings in chapter
