Product Description:

The HDS03.2-W075N-HT05-01-FW is an axis module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a servo inverter stage, it supplies and regulates power between a DIAX04 supply unit and a connected servo motor group, carrying out positioning and velocity loops in automated machinery. Within an industrial cell, the unit interprets digital motion commands and translates them into controlled three-phase output for coordinated multi-axis movement. This arrangement supports synchronized operation in machines that use several servo axes within a shared drive rack.

Its communication layer relies on the SERCOS fiber-optic ring, providing deterministic exchange of setpoints and feedback with the central controller during cyclic motion control. The module can deliver a continuous current of 75 A, giving sufficient headroom for medium-to-large torque motors during acceleration phases and changing load conditions. Thermal management is handled by a built-in air blower, which moves air across the heat sink channels so no external fan tray is required. The unit uses the DIAX04 backplane format for plug-in compatibility with supply units and accessory cards installed in the same platform. It is part of Line 03, which identifies the housing size and connector spacing used in this drive rack format.

The product is classified as an HDS Drive Controller, so current regulation and control logic are handled inside the module. It is listed as Version 2, indicating the hardware revision for this unit. The embedded command interface allows the controller to operate on the optical ring without a separate command card, and parameter storage is integrated on the board. This layout keeps the control electronics self-contained while maintaining compatibility with the rest of the rack-based drive system.
