Product Description:

The HDS03.1-W100N-HA15-01-FW is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Engineered for the DIAX04 multi-axis platform, the module converts motion commands from higher-level controls into power signals that drive synchronous and spindle motors. This role makes the unit a central component in automated machining centres, material-handling cells, and packaging lines where precise speed and position loops must be closed inside the controller itself.

Its data path is managed through a command communication interface that accepts set-point signals in a strictly ANALOG format, so integration with legacy PLCs that deliver ±10 V references is straightforward. Inside the DIAX04 rack, the controller occupies the slot allocated to Line 03, matching the pinout and bus geometry defined for that hardware generation. The current stage is rated for a continuous output of 100 A, allowing it to energize medium-power servo axes without external boost modules. Thermal energy produced by switching losses is removed by a built-in internal air blower; the fan circulates cabinet air across heat sinks, eliminating the need for ducted external cooling.

Produced by Bosch Rexroth Indramat, the unit adheres to the electrical layout and mounting footprint common to the HDS Drive Controllers series, so replacement or parallel expansion can be performed without cabinet redesign. The design is identified as Version 1, meaning component revisions, microcode level, and test routines correspond to the first released hardware iteration. By combining firmware logic, power semiconductors, and fan assembly into a single module, the controller simplifies cabinet wiring and shortens commissioning time for multi-axis cells that rely on a centralized drive backbone.
