Product Description:

The HDS03.2-W075N-HT10-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. This module is designed to control servo and main drives in a DIAX04 multiaxis system, converting command data from a central motion controller into regulated current for connected motors. By handling vector control, protection, and status feedback, the unit supports coordinated industrial automation tasks such as machining centers and material-handling lines. In operation, it serves as the power and control stage for an axis, translating motion requests into controlled motor response while monitoring operating status. That arrangement allows one controller to manage current regulation for a connected motor while still reporting faults and status signals back to higher-level controls.

Command data reach the controller through the SERCOS optical fiber interface, which provides deterministic real-time communication so axis commands and diagnostic messages share one synchronized channel. Within the product line, the device is assigned to Line 03, and its power electronics support a continuous output of 75 A for medium-power servo axes. Thermal management is handled by a built-in air blower that directs cabinet air across the heat sink without additional ducting. This cooling method helps remove internal heat while the controller remains installed in a multiaxis rack beside related drive modules. The synchronized optical link reduces the need for separate command wiring between the central control and the drive rack.

The unit is supplied as Version 2. It mounts beside supply modules in the same rack and uses a shared DC bus with the system fault circuitry. The controller processes communication telegrams according to the DIAX04 profile, which keeps parameter structure consistent across multiaxis installations. Because it sits beside the supply section, the module fits the same rack arrangement used for coordinated drive assemblies. Its rack-mounted form also helps keep cabinet layouts orderly when several axes are installed side by side.
