Siemens 6SE7090-0XX84-0AJ0 Drive Board Module

Siemens 6SE7090-0XX84-0AJ0 Drive Board Module is a CU2 control-board component for the SIMOVERT Masterdrives system, designed to support vector-control configurations in industrial drive applications by providing the control logic and interface needed to manage motor performance within the CU2 unit. The AJ0 variant is described as an MWH module for the CU2 control unit, while the 0AF0 (AF0) version is the drive board that enables open- and closed-loop control within the same CU2 platform. These boards reside inside the CU2 to govern motor drive functions and integrate with the SIMOVERT Masterdrives control architecture for precise torque and speed management in vector-control configurations. The AF0 variant is listed as discontinued with end-of-life support as of May 8, 2008, reflecting its status as a legacy component in older Masterdrives installations.
