HDS03.1-W075N-HT13-01-FW
The HDS03.1-W075N-HT13-01-FW is a drive controller module produced by Bosch Rexroth Indramat. Within multi-axis automation cabinets, it links individual power sections to common supplies and feedback networks, supporting coordinated motion control for servo axes and similar equipment. Its role is to modulate current, monitor status, and exchange real-time commands with higher-level PLCs so that connected motors receive precise torque and velocity instructions during machine cycles. It is intended for centralized drive cabinets where several axes share a common supply structure instead of using separate standalone controllers.
The command channel is the SERCOS fiber-optic interface, which allows deterministic telegram traffic between the controller and the motion processor. The interface supports high-speed cyclic communication during synchronized axis operation. During operation, it can deliver up to 75 A of continuous output current to the attached power section, supporting rated torque output on each axis under normal conditions. Heat generated by switching devices is removed by a built-in air blower, so the electronics can operate without external ducting. The model is part of Line 03, and its function modules share the architecture of the DIAX04 controller family. This keeps the module aligned with the same control platform used by related axes in the system.
The product is Version 1. It is classified as an HDS Drive Controller, and its housing layout, terminal labels, and diagnostic indicators follow the format used across the HDS Drive Controllers series. In cabinet-based drive systems, that consistent layout keeps optical communication routing, power section placement, and front-panel access organized across adjacent modules. Cabinet installation should account for mains supply capacity, cooling airflow, and optical ring timing so the module can operate within its electrical and thermal limits. Those limits apply while the controller exchanges commands, monitors feedback traffic, and supports stable axis response during repeated machine cycles.
