Product Description:

The HDS03.2-W075N-HS28-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. It acts as the power and control stage for multi-axis motion systems, converting command data from the higher-level automation platform into regulated motor currents for connected axes. In automated machining centers, packaging lines, and material-handling cells, the unit supplies precise torque and velocity commands so servomotors follow programmed motion profiles with controlled acceleration, steady running speed, and repeatable response during cyclic machine operation.

Communication with the supervisory motion processor occurs over the fiber-optic SERCOS interface, allowing deterministic cyclic data exchange through a single ring and consistent synchronization between the controller and the motion system. The controller belongs to the DIAX04 family and shares plug-in power sections and common backplane connections with other modules in that platform, which helps it fit into established rack layouts. Thermal management relies on a built-in air blower, which draws cooling air across the heat sink without external ductwork. The power stage is rated for a continuous output of 75 A, enabling it to energize medium-frame servomotors that demand high peak current during acceleration. The unit is part of Line 03.

The unit is Version 2. It uses the common supply and feedback cable arrangement applied across the HDS Drive Controllers series, so related modules in the same multi-axis assembly can follow the same connection pattern for power distribution and feedback routing. The controller also follows the protective-circuit arrangement used on this platform, which supports operation with matching supply sections and motor feedback paths. This allows the module to be installed in existing racks without changing the surrounding module positions or the normal cabinet cooling path.
