Product Description:
The HDS03.2-W100N-HA32-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. Within a multi-axis rack, it energizes and regulates synchronous and induction motors used in material-handling cells, presses, and machining centers. By converting motion commands from higher-level controls into regulated armature current, the unit closes the velocity and torque loops required for precise industrial automation. Its modular format lets it work with separate supply and control elements inside the rack rather than as a standalone unit.
The control card communicates through the DIAX04 backplane, which forwards an analog ±10 V speed reference and the related feedback signals. Continuous motor demand is supported by a bus supply that allows the controller to deliver up to 100 A of output current. Thermal loads are managed by a built-in air blower that draws cabinet air across the heat sink to keep the power section within its operating range. This airflow helps remove switching losses during sustained current delivery without adding an external cooling device. The unit is part of Line 03, and its power stage footprint and connector locations match other third-generation HDS modules used in DIAX04 racks.
The controller is Version 2. Classified as an HDS Drive Controller, the module interfaces directly with regenerative supply units and select auxiliary cards. Direct compatibility with regenerative supply units also supports shared DC-bus operation across coordinated axes in the same rack. It is part of the HDS Drive Controllers series, so diagnostic LEDs, terminal coding, and address selection follow a common layout across compatible rack assemblies. That standardized layout keeps signal routing and module identification straightforward when the controller is installed beside other drive components in the same cabinet.
