HDS03.1-W075N-HA30-01-FW
The HDS03.1-W075N-HA30-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and placed within the HDS Drive Controllers series. This unit regulates power for servo axes and coordinates motion in multi-axis racks, allowing precise speed and torque control in automated machinery and production lines. By converting command signals into regulated three-phase output for connected motors, it serves as the link between higher-level PLC logic and electromechanical actuators. This allows the connected motor to respond quickly to changing process loads while maintaining stable operation during repeated machine cycles.
The controller accepts reference signals through an analog command interface, so velocity or torque demands are conveyed as ±10 V levels that the control loop can track in real time. A continuous output capacity of 75 A supports high-current motors used on pressing, printing, or gantry axes, while overload detection inside the loop protects semiconductors from sustained surges. Thermal stability is maintained by a built-in air blower, which removes heat without external ducting. The device belongs to the DIAX04 platform, so its parameter structure and connector pinout match other compatible axes in the rack. The cooling system works with temperature sensors on the heat sink, so fan speed adapts to actual dissipation and helps limit acoustic noise during light-duty cycles.
Within the rack, the unit occupies Line 03 and is built as Version 1. It integrates current, velocity, and position loops in one module, supporting coordinated axis control for demanding motion applications. The controller also includes SERCOS passthrough connectors and diagnostic LEDs, which keep signal routing and status indication consistent across compatible rack slots. Its integrated control functions reduce the need for separate external regulation hardware inside the drive assembly.
