HDS03.2-W075N-HT20-01-FW
The HDS03.2-W075N-HT20-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It is designed for mounting in modular motion control racks where it closes current, velocity, and position loops for synchronous or induction motors. By converting setpoint data from a central motion master into controlled power output, the module coordinates multi-axis movement and monitors operating status during machine operation. In automated systems, it supports accurate acceleration, speed regulation, and position holding on axes that must respond quickly to command changes.
Communication between the rack backplane and external motion sources uses the command communication interface, which in this model is the real-time SERCOS fiber-optic link. That protocol delivers deterministic telegrams, allowing the controller to update drive values at short intervals without separate analog wiring. Because the communication path is digital, command transmission is less affected by electrical noise from surrounding power equipment, which helps maintain repeatable motor response during synchronized starts, stops, and speed changes across multiple axes. The power section is rated for a continuous output of 75 A, and thermal management is handled by a built-in air blower so heat is removed internally without routing cabinet airflow through the heat sink.
The unit is part of the DIAX04 platform and belongs to Line 03 in that product range. Within this line, version 2 identifies the revision used for this controller. The module fits multi-axis rack systems that use a common diagnostic and parameter structure, which helps keep axis behavior consistent within the same control platform. Signal processing and power control are integrated in one housing, allowing the controller to serve as both the regulation stage and the power stage for connected motors. This arrangement suits coordinated machinery where several drive modules share the same rack and exchange status information through the system backplane. It can be used on packaging, handling, and process equipment that requires stable closed-loop motor control.
