Product Description:

The HDS03.2-W075N-HS03-02-FW is a modular drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed for multi-axis packages in the DIAX04 automation platform, the unit converts drive commands into regulated current for connected servomotors and supports coordinated motion in systems that combine several axes in one cabinet or machine section. In production lines, handling equipment, and machine tools, it acts as the intermediary between higher-level PLCs and the power section, issuing torque and velocity orders while monitoring motor feedback for closed-loop regulation during acceleration, deceleration, and steady-speed operation.

The controller communicates through the SERCOS interface, so parameter sets, status words, and real-time motion data move over deterministic serial rings rather than copper fieldbuses. The power section is rated for a continuous output of 75 A, which allows the device to energize medium-frame motors without external current boosters and to sustain demanding axis loads during steady operation. Heat generated by the switching transistors is removed by a built-in air blower, letting the module operate in dense cabinets without ducted cooling and helping maintain stable thermal conditions around the heat sink. As part of the DIAX04 platform, it is intended for use with synchronous and asynchronous motor combinations supported by that system, so it fits into established drive assemblies with a shared control architecture. The product is part of Line 03, indicating the geometry and connector layout shared with companion amplifier cards.

The controller is Version 2, with expanded diagnostic objects and timestamped error logs compared with earlier revisions, which improves visibility into drive events during operation. The HS suffix marks it as a high-speed axis module intended for fast-response motion tasks where quick current regulation and accurate status reporting are important. As an HDS Drive Controller, it supplies axis current, stores parameter sets in nonvolatile memory, and forwards operating states to the master without duplicating the role of external motion cards.
