HDS04.1-W200N-HS72-02-FW
The HDS04.1-W200N-HS72-02-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It converts incoming DC bus energy into regulated three-phase output and sends motion commands to connected motors, enabling precise axis coordination in assembly lines, packaging systems, and machining cells. The module mounts beside the central supply section and uses a shared DC link, so multiple drives can operate from one power source while keeping the cabinet layout compact. This arrangement is typical in modular drive racks where several axes share incoming power from a central supply section.
The controller has a continuous output capability of 200 A, allowing it to energize large torque motors without external amplifiers. Command data travel through the SERCOS fiber-optic interface, giving deterministic cycle times and good immunity to electrical noise in industrial cabinets. Within the DIAX04 family, the module follows the same parameter structure and diagnostic format used by related axes, which helps maintain consistent operation across a multi-axis system. Thermal stability is maintained by a built-in air blower that draws cabinet air across the heat sink and removes heat without liquid circuits. The combination of high current capacity and fiber-optic communication suits servo or spindle axes that require fast response and steady regulation under changing loads.
The unit is part of Line 04, so its backplane connectors and DC bus bars align with adjacent modules in the same rack. The current hardware revision is 1, which identifies this release level within the platform. The product is classified as an HDS Drive Controller, and that designation places it within the HDS platform for operating characteristics, parameter handling, and diagnostics. It is intended for rack-based installations where module spacing, bus alignment, and interface consistency matter for system integration.
