HDS03.1-W075N-HS74-02-FW
The HDS03.1-W075N-HS74-02-FW is an axis controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for rack-mounted multi-axis assemblies, it closes current and velocity loops for servo motors and routes motion commands from higher-level control systems. The unit supports mid-range torque demands commonly found in packaging, printing, and material-handling lines. Within an installation, it occupies one slot on the system backplane and acts as the bridge between the power supply module and the motor feedback devices. This role supports coordinated motion in systems where several axes share a common supply section and centralized control source.
Deterministic axis coordination is achieved through the SERCOS optical interface, which transmits setpoints and status data with minimal jitter. The controller supplies up to 75 A of continuous inverter current, so servo motors can accelerate quickly without exceeding the rated thermal envelope. Cooling relies on a built-in air blower that circulates air across the heat sink fins, allowing full-load operation without external cabinet fans. The unit follows the DIAX04 architecture, and Line 03 identifies the product design line used for this version. By combining optical communication with integrated cooling, the controller supports stable axis response during continuous motion tasks.
The unit is Version 1 and functions as a drive controller that receives DC bus power from an external supply module and delivers phase-modulated energy to the connected motor. This arrangement lets the module handle power conversion and axis regulation without serving as a standalone power source. Its rack-mounted format supports orderly wiring between adjacent modules and helps keep multi-axis assemblies compact. The controller is intended for systems that rely on centralized power distribution and coordinated motor feedback processing during normal operation.
