HDS03.1-W075N-HS47-01-FW
The HDS03.1-W075N-HS47-01-FW is a drive controller produced by Bosch Rexroth Indramat for modular motion systems in the HDS Drive Controllers series. The module functions as a closed-loop axis controller that interprets digital commands and delivers regulated three-phase power to servo motors. Within an industrial cell, it links upper-level PLC sequences to mechanical movement by translating speed, torque, and position requests into precise motor current. Because command processing and power regulation are combined in one module, the controller supports coordinated axis motion in packaging, printing, and material-handling equipment that requires repeatable response during speed changes and positioning moves.
The command channel is the SERCOS optical interface, so setpoint, feedback, and synchronization data move in real time on a deterministic ring. Parameter storage follows the DIAX04 family layout, which keeps data organization consistent across adjacent axes. A built-in air blower pushes cabinet air across the heat sink, maintaining semiconductor temperature without external ducts or water lines. The power stage is sized for a continuous output of 75 A, which is the upper limit for RMS motor current during acceleration and sustained load. The controller belongs to Line 03, which identifies the third platform revision used for this product line.
The unit is released as Version 1, and its component layout and diagnostic behavior match the initial production build. Classified as an HDS Drive Controller, the module slides into the common power rack and locks to the shared DC bus and 24 V logic rail without additional cabling adaptations. This arrangement supports compact multi-axis installations where several controllers operate from the same central supply structure. The rack-based connection method also reduces external interconnect points between neighboring modules.
