HDS03.2-W075N-HT29-02-FW
The HDS03.2-W075N-HT29-02-FW is a modular drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. Serving as the power and control module in an industrial automation rack, the unit coordinates current, velocity, and position loops for connected servo axes. In production lines, packaging systems, and machine tools, it links motor power electronics to higher-level motion commands and provides the closed-loop regulation needed for repeatable mechanical movement. Its modular format allows it to operate as part of a larger drive system rather than as a stand-alone controller. That arrangement helps the controller regulate motor response during acceleration, steady running, and positioning moves under changing loads.
This version uses the SERCOS optical interface to receive drive commands and diagnostic data, so it can operate on a high-speed fiber ring with other axes. Its output stage is rated for 75 A, which supports medium-power servo and spindle motors in the same cabinet. Thermal management is handled by a built-in air blower that circulates air through the heat sink channels to keep semiconductor temperatures within allowable limits. This cooling method is suited to cabinets that use filtered airflow instead of liquid cooling. The controller belongs to design 03 of the HDS line and is built as version 2, so it should be used with the matching parameter set for this generation.
The controller is intended for the DIAX04 multi-axis family, where it slides into a common backplane that distributes DC bus power and logic signals from the supply unit. Its housing occupies one slot in the rack, allowing installation without additional brackets. The shared backplane reduces separate point-to-point wiring inside the cabinet and keeps the power section integrated with the supply unit. This layout also supports orderly module placement when several axes are installed side by side. Electrical limits associated with the rated current help protect connected motors against overload during normal use.
