HDS03.2-W075N-HS03-02-FW
The HDS03.2-W075N-HS03-02-FW drive controller is produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed for multi-axis automation, the unit receives digital motion commands, shapes three-phase current, and manages velocity loops to drive servo motors in packaging, machining, and material-handling equipment. By translating setpoints from a central PLC into controlled motor torque, it provides the closed-loop regulation needed for precise positioning and stable speed control on a single axis. The controller also supports repeatable motion response during indexing, speed changes, and holding phases.
The command path is based on the SERCOS fiber-optic bus, and the associated command communication interface exchanges position words and diagnostic data every cycle, enabling deterministic update times in synchronized machine networks. Cyclic data transfer over the optical link helps the control system coordinate axis motion with low latency. This module belongs to the DIAX04 controller family, so it fits the common backplane alongside power supplies and auxiliary cards without additional cabling. Thermal management is handled by a built-in air blower, which moves heat away from the power section and control electronics during operation. This active airflow supports continuous operation under the specified load.
The module has a rated current of 75 A when mounted in a 45 mm slot. That current level suits servo axes that require steady output during acceleration and continuous running. The stated slot width helps determine spacing in the drive rack and keeps airflow paths consistent across adjacent modules. The unit is part of Line 03, which identifies its design line within the product range. The drive is Version 2, indicating the revision used for this model.
