HDS03.2-W075N-HA38-01-FW
The HDS03.2-W075N-HA38-01-FW is a single-axis drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a modular automation rack, the module sits between the central supply unit and the servo motor, shaping current and voltage to carry out speed or torque commands from a CNC or PLC. By handling closed-loop regulation inside the drive, it reduces the control burden on the supervisory processor. This supports precise positioning, tension control, and electronic gearing in printing, packaging, and handling equipment. Because current regulation is managed within the module, response to load changes remains fast during indexing and synchronized motion tasks.
The unit exchanges motion setpoints through an analog command interface that maintains compatibility with earlier motion cards. Its output stage is rated for 75 A, giving headroom for rapid acceleration without thermal derating. Internal temperature rise is controlled by a built-in air blower that circulates cabinet air across the heat sink fins, so no external ductwork is required. Analog input control makes the unit suitable for systems that use voltage-based reference signals instead of serial motion networking. The module is part of the DIAX04 family and uses the rack dimensions and connector spacing associated with that platform. The unit is part of Line 03 in the series, which identifies its design line.
The module is Version 2, indicating the second release of this model. Its official product type is HDS Drive Controller, meaning the power electronics and signal processing functions are housed in one chassis. This layout allows the controller to regulate motor operation at the axis level while the higher-level control manages overall machine coordination. Separating the supply unit from the axis controller also supports rack-based layouts where multiple drives share a common power source. The result is a compact control arrangement for modular servo systems that require consistent response during repeated operating cycles.
