HDS03.2-W075N-HT04-01-FW
The HDS03.2-W075N-HT04-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Designed for multi-axis automation within modular motion systems, the unit converts drive commands from a central motion controller into regulated current for servo motors. In a machining cell or assembly line, it closes the control loop between fieldbus instructions and motor torque, enabling synchronized motion across several mechanical axes. This arrangement supports coordinated speed and torque control where several drives must respond together during indexing, transfer, or positioning tasks.
The command channel is routed through the SERCOS fiber-optic interface, so real-time setpoints and feedback are exchanged in a deterministic data stream across the ring. Within the DIAX04 controller family, this model is part of Line 03, which gives it mechanical dimensions compatible with matching power supplies and interconnection modules. Thermal management is handled by a built-in internal air blower that draws cabinet air across the heat sink to keep semiconductor junctions within rated limits during continuous duty. The power stage can deliver a sustained output of 75 A, allowing it to drive medium-frame synchronous or asynchronous motors at full torque. This combination of communication, cooling, and output capacity supports stable operation in cabinets where multiple axes are installed side by side.
The controller is Version 2, which identifies the product revision used for this unit. Integrated diagnostics support status monitoring and fault reporting during operation, helping the control system detect drive events and operating states without separate monitoring devices. The module fits with matching rack components used in the same drive platform, so adjacent power supplies and interface modules can share a common cabinet layout. Status information can be passed through the control system so operating conditions remain visible at the machine level. The unit serves as the current-regulating drive stage for the connected motor rather than as a separate supply or communication module.
