Product Description:

The HDS03.1-W100N-HS24-01-FW is a drive controller built by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. As a modular unit for the company’s DIAX multi-axis platform, it governs torque, speed, or position loops for permanent-magnet servo motors installed on production machinery. In an automation line the controller receives motion commands from a higher-level CNC or PLC, executes current-regulated drive tasks, and returns status data so the supervising system can coordinate multiple axes in real time.

The control loop communicates through the optical SERCOS fieldbus, which provides deterministic timing and noise-immune transmission for synchronized motion segments. Within the DIAX architecture the unit sits in the DIAX04 controller family, meaning its firmware, parameter structure, and plug-in power section conform to that generation’s standards. Thermal management relies on a Built-in Internal Air Blower; the impeller forces cabinet air across heat sinks so the drive can shed switching losses without external ductwork. The power section carries a continuous output of 100 A, enabling it to energize medium-inertia servomotors that demand high peak currents during acceleration. The type code indicates line 03, specifying mechanical dimensions and back-plane connector alignment identical to other third-line HDS modules.

Additional configuration data finish the model description. Firmware and hardware correspond to Version 1, so parameter files written for that release load without conversion utilities. The catalog lists no other versions for this specific current rating, simplifying spare-part logistics because cross-version compatibility checks are unnecessary. Its classification as an HDS Drive Controller distinguishes it from HDC or HDD inverters that support other motor technologies, and the standardized command communication interface ensures it can be swapped into any DIAX04 rack that already hosts SERCOS drives without disturbing network timing.
