ABB ACS800-67LC User Manual

36 Operation principle and hardware description
Control unit of the rotor-side converter
The rotor-side converter is controlled by its own NDCU control unit. The NDCU is
connected to the rotor-side converter power modules by a fiber optic link, distributed
through APBU optical branching unit. In the rotor-side converter modules the fiber optic
link is connected to the AINT board.
 Control unit NDCU-33Cx/RDCU-12C
The connectors of the rotor-side converter control unit NDCU-33Cx (consisting of the
NIOC-02C and AM33C boards) and the grid-side converter control unit RDCU-12C
(containing the RMIO-12C board) are shown below. For further information on the RDCU
control unit, see RDCU drive control units hardware manual [3AFE64636324 (English)].
