HDS03.1-W100N-HS47-01-FW
The HDS03.1-W100N-HS47-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a stand-alone axis module, it serves as the power stage in DIAX04 multi-axis systems, supplying regulated DC bus energy and closed-loop control to compatible servo motors. By converting commands from a higher-level control network into regulated current and voltage, the unit supports accurate position, speed, and torque control in material-handling, packaging, and machining equipment. It is intended for applications where each drive axis must respond quickly to changing loads and commanded motion profiles. This arrangement lets one controller regulate a motor directly while remaining coordinated with the rest of the machine.
Communication with the controller is handled over the SERCOS fiber-optic ring, allowing deterministic real-time data exchange between the drive and the central PLC. The optical link supports synchronized command transfer and status reporting during coordinated axis motion. The output stage is rated for 100 A, so the module can operate high-torque servomotors without an external booster stage. Thermal stability is maintained by a built-in air blower that moves cabinet air across the heat sink, so no liquid cooling circuit is required. The product is part of Line 03, which identifies the third design line for this controller type.
The unit is Version 1, indicating the initial release of this controller variant. Its matching bus connectors and mounting rails align with adjacent modules in the cabinet. That arrangement keeps the physical stack uniform across neighboring axes. It also helps maintain orderly airflow paths around the heat-generating sections of the drive assembly. The consistent layout supports clean cabinet organization when several axes are installed side by side.
