HDS03.2-W075N-HA20-01-FW
The HDS03.2-W075N-HA20-01-FW is a drive controller module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for multi-axis assemblies, the unit processes reference commands and delivers controlled power to servo motors in CNC machines, printing stations, and automated transfer lines. Inside a compact drive rack, it converts motion setpoints into regulated current loops so each connected motor can maintain precise velocity, torque, and position during continuous production. This operating role makes it suitable for coordinated axes that must accelerate, stabilize, and correct motion errors while remaining synchronized with the rest of the machine.
The controller can supply up to 75 A of continuous output, so surrounding power components and cabling must be sized for that current. Command data reach the unit through an analog interface, allowing direct velocity or torque references from legacy PLCs and similar control hardware. Thermal stability is maintained by a built-in air blower that circulates cabinet air across the heat sinks instead of relying on external ducts. The module is part of the DIAX04 control family, and its Line 03 designation matches the mechanical layout and connector orientation used by third-generation HDS backplanes. These characteristics support steady operation in machines that run long duty cycles with repeated starts, stops, and speed changes.
The unit is identified as Version 2, indicating the second revision of this controller design while keeping the mounting pattern unchanged. The updated revision preserves the established rack geometry, which helps maintain a consistent physical fit within the platform. Its control architecture is well suited to feed axes, indexing stations, and transfer motions that depend on stable current regulation over extended operating periods. Analog command handling also supports integration with motion systems that use conventional reference signals instead of a digital fieldbus.
