HDS05.2-W300N-HA16-01-FW
The HDS05.2-W300N-HA16-01-FW is a drive controller module produced by Bosch Rexroth Indramat and included in the HDS Drive Controllers series. It is used in industrial automation to regulate power flow between a DIAX04 supply unit and a connected servo or spindle drive within a modular multi-axis system. By processing command values and switching high currents, the module supports torque, speed, and position control in machine tools, packaging lines, and material-handling equipment. In a multi-axis cabinet, it works with the supply section to convert DC-bus energy into controlled motor current for accurate axis response.
Its control channel relies on an analog reference, so the controller expects ±10 V speed or torque commands from the master motion system. The unit belongs to the DIAX04 family, which uses compatible encoder formats and diagnostic codes across related modules. Thermal load is managed by a built-in air blower, which directs airflow over the heat sink and supports continuous operation under high current demand. The drive can deliver a continuous output of 300 A, allowing it to supply large servo or spindle motors in heavy-duty applications. Because the command interface is analog, the controller can be paired with motion systems that send setpoints as voltage signals rather than digital communication data.
The unit is part of Line 05 and is built in Version 2, which identify its design generation within the product range. It is classified as an HDS Drive Controller, so the assembly includes power output stages, resolver evaluation, and short-circuit monitoring in one module. The internal logic and blower use 24 V control power, so the supporting supply must remain available for normal operation. Combining power conversion and feedback evaluation in one housing reduces the need for separate control stages inside the drive rack.
