General
The supply unit of the drive is controlled by a dedicated ZCU-14 control unit (component
designation A51). The ZCU-14 unit consists of a ZCON control board contained in a plastic
housing.
The inverter unit of the drive is controlled by a dedicated BCU-x2 control unit (component
designation A41). The BCU-x2 consists of a BCON control board (and a BIOC I/O connector
board and power supply board) built in a metal housing.
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.
