HDS05.2-W300N-HS72-02-FW
The HDS05.2-W300N-HS72-02-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It is a power module for industrial automation systems that manage servo axes requiring fast current regulation and coordinated multi-axis motion. When installed in a modular rack, the unit conditions incoming DC bus energy, processes motion setpoints, and supplies controlled three-phase output to the connected motors. Because it works from a shared DC bus, the controller can serve as the regulated output stage for machines that coordinate several servo axes at the same time.
At the communication level, the controller relies on the SERCOS interface, so command and feedback data move through a deterministic fiber-optic ring with synchronized updates across connected drives. The unit is part of the DIAX04 platform, which gives it the same general mechanical format and connector layout used by related modules in that system. Thermal management is handled by a built-in air blower, which moves cabinet air through the heat sink without requiring external ducting. The power channel can deliver a continuous 300 A of motor current, providing the current capacity needed for large torque demands on high-inertia axes. This combination of synchronized communication and internal airflow suits cabinet-based multi-axis drive assemblies.
The controller is assigned to Line 05, which identifies this design line within the platform. It is also Version 2, indicating the second product version for this model. These identifiers distinguish the unit from other design lines and product revisions without changing its basic role as a rack-mounted drive controller. In operation, the unit remains focused on regulated motor output, real-time communication over the optical network, and heat removal through cabinet airflow. The result is a controller that fits high-power servo applications where several axes must operate together under centralized motion control.
