HDS03.2-W075N-HT82-01-FW
The HDS03.2-W075N-HT82-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in a compatible rack backplane, it converts the shared DC bus into regulated motor power for servo axes. The module links motion commands to motor torque, speed, and position loops, allowing machine tools, packaging stations, and handling robots to perform repeatable coordinated moves. Its cabinet-mounted format suits compact multi-axis automation systems that need centralized power conversion and precise control. It is intended for industrial automation cells that combine several motion channels within a single control cabinet.
The controller exchanges setpoints and diagnostics through the SERCOS interface, allowing deterministic communication over a fiber ring. Fiber-optic communication helps maintain timing consistency when multiple axes must follow synchronized motion profiles. A continuous output of 75 A supplies medium-power motors while preserving dynamic torque capability, and this current value states the maximum RMS output the unit can deliver continuously. This output level fits medium-power servo motors used on feed axes, transfer units, and rotary indexing stations. Heat is removed by a built-in air blower, so airflow is generated inside the drive without requiring separate external cooling devices. The controller is Version 2, which identifies the product revision used for this model.
As part of the DIAX04 platform, the unit uses the same general system architecture as neighboring axes in the rack. It is assigned to Line 03, placing it within the third design line of the product range. The assigned line also marks the mechanical format used by this controller type. The drive supports coordinated servo control in applications that need accurate current regulation, stable speed control, and repeatable axis positioning. Its regulated three-phase power output lets the connected motor respond closely to command changes during acceleration, indexing, and contouring tasks. In these systems, it operates with supply and feedback modules that manage the remaining parts of the motion chain.
