General
The 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 drive 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 connected to the power modules (ie. supply and inverter modules respectively) by fiber
optic cables.
In this manual, the name "BCU-x2" represents the control unit types BCU-02 and BCU-12.
These have a different number of power module connections (2 and 7 respectively) but are
otherwise similar.
