Product Description:

The HDS03.1-W100N-HA44-01-FW drive controller is produced by Bosch Rexroth Indramat as a member of the HDS Drive Controllers series. It forms part of a modular servo system where the controller supplies regulated current to synchronous and induction motors used in factory automation lines. By linking to the shared DC bus and motion control electronics, it closes the power loop that positions machine axes with repeatable accuracy during indexing, feeding, and synchronized transfer tasks. Its role in the system is to convert available DC power into controlled motor output for coordinated motion.

This model receives command signals through an analog interface, so speed or torque references arrive as continuous voltage levels. Its continuous output capability is rated at 100 A, which is the maximum motor phase current the internal power stage can deliver while the heat sink remains within its operating range. Thermal management is handled by a built-in air blower; the integrated fan moves air across the cooling channels and supports stable operation without requiring a separate external blower on the unit. The hardware layout follows the DIAX04 platform, allowing mechanical and electrical compatibility with other controllers built for the same system structure. The unit is version 1, indicating the product revision used for this model.

The unit belongs to Line 03, which uses the housing height and connector arrangement assigned to that group. It is an HDS Drive Controller intended for modular drive assemblies that combine power conversion, axis control, and shared supply architecture in one coordinated system. This arrangement keeps the controller aligned with the mounting and connection pattern used across related modules. The result is a layout that fits cleanly into multi-axis installations where consistent module spacing and orderly wiring are important.
