HDS03.2-W100N-HS72-02-FW
The HDS03.2-W100N-HS72-02-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Designed for cabinet-mounted drive stacks, the unit converts DC bus energy into modulated phase current for servo motors in industrial automation cells. Closed-loop control electronics and optical communication let it serve as the motion interface between a PLC and mechanical axes. The controller modulates motor current in real time, so the connected axis can follow motion profiles from the higher-level control without relying on separate external regulation hardware. Because regulation is handled inside the drive, commanded speed, torque, and position can be maintained across changing loads in packaging machines, metal-cutting centers, and material-handling robots.
It supplies up to 100 A of regulated output, so high-inertia loads can be driven without exceeding thermal limits. Motion telegrams are exchanged over SERCOS, a deterministic fiber-optic interface that supports synchronized multi-axis communication. The unit is part of the DIAX04 family, so it shares the rack format and connector arrangement used by related modules. Cooling is handled by a built-in air blower that moves airflow along the power stage to remove switching heat. The module is in Line 03 of the product line. This arrangement suits coordinated installations with several controlled axes operating from the same machine platform.
The unit is Version 2, which provides expanded diagnostic reporting while keeping the established command structure. Front-panel status LEDs and the fault-word display show operating state and alarm conditions in a direct way. This drive can be used in mixed-axis cabinets where servo and spindle sections share a common DC bus. Diagnostic messages can distinguish communication interruptions, overload events, and feedback-related faults, which keeps fault handling clear within the cabinet. Its control section supports stable coordination with the rest of the drive stack during acceleration, holding, and commanded position changes.
