HDS03.1-W075N-HS03-02-FW
The HDS03.1-W075N-HS03-02-FW is a digital drive controller engineered by Bosch Rexroth Indramat to manage coordinated servo axes in industrial automation. Installed in modular racks, it converts real-time motion commands into regulated motor currents and provides closed-loop torque and velocity control for printing presses, packaging equipment, and material-handling lines. The controller serves as the power stage for axes that require synchronized response under changing load conditions. By combining power electronics and cooling hardware in one housing, it operates as a self-contained unit within the HDS family of multi-axis drive controllers. In automated equipment, this allows the drive to respond quickly to command changes while maintaining stable motor behavior during starting, running, and deceleration.
Within a rack, the module delivers up to 75 A of output current, allowing sizable servo motors to accelerate without current foldback. Heat generated by the IGBT bridge is removed by a built-in air blower that draws cabinet air across the fins, so external ducting or liquid circuits are unnecessary. Command data reaches the controller over SERCOS, a fiber-optic motion bus that supplies synchronized position, velocity, and diagnostic data during each cycle. The unit follows the DIAX04 controller family layout, which standardizes power terminals, feedback connectors, and module dimensions across compatible axes. This arrangement supports orderly integration in cabinets that use several coordinated drive modules.
The identification codes refine how the unit fits into an HDS rack and indicate where it belongs within the product line. The unit is part of Line 03, which indicates the design line used for its backplane spacing and conductor pinout. The product is Version 1, matching the initial release used for this controller type. It is part of the HDS Drive Controllers series, so it shares the rack-based module format used across that platform. It also uses the same general rack mounting concept found across related HDS modules.
