Product Description:

The HDS03.2-W075N-HS56-01-FW is a modular drive controller from Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Designed for the DIAX04 multi-axis platform, the unit coordinates servo axes and regulates power flow between the supply and the motor in automated machinery. By converting command data from the higher-level motion system into precise current and voltage patterns, the controller enables synchronized positioning, speed regulation, and torque control in printing lines, packaging machines, and material-handling cells. This allows the connected axes to respond quickly to changing loads while maintaining coordinated motion during continuous machine cycles.

Its continuous output path is dimensioned for a maximum phase current of 75 A, so compatible servomotors can draw the required current without overloading the power stage. Command data reach the controller through the SERCOS fiber-optic bus, allowing deterministic telegram exchange and daisy-chain wiring. Thermal management is handled by a built-in air blower; the impeller forces cabinet air over the heat sink fins, keeping semiconductor junctions within operating limits under sustained cyclic operation. The unit is part of the DIAX04 modular family, which gives it standardized connector layouts and parameter sets that match other members of the platform. The designation places this device in Line 03, indicating rack compatibility within the multi-axis system.

Within the same mechanical frame, the electronics are identified as Version 2, which uses revised signal conditioning and updated diagnostics compared with earlier releases. As an HDS Drive Controller, the module shares a unified parameter structure with supply and clamp cards in the same system. During operation, the controller monitors the current limit and modulates switching patterns in real time to keep junction temperatures compatible with the airflow provided by the blower. The updated diagnostic behavior also supports clearer status reporting during normal machine operation.
