HDS03.1-W075N-HT10-01-FW
The HDS03.1-W075N-HT10-01-FW is a modular axis drive unit produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a servo drive controller, it is installed in multi-axis racks to regulate power conversion and command electromechanical actuators in automated machinery. By coordinating torque, velocity, and position feedback, the unit links CNC or PLC commands to the motors that move tooling, conveyors, and material-handling stages. This arrangement allows several synchronized axes to operate from a centralized cabinet layout.
The drive delivers a continuous output current of 75 A, allowing it to energize medium-power servo axes without an added external amplifier stage. Data and real-time setpoints are exchanged through the SERCOS fiber-optic interface, so the controller can operate within high-speed motion networks while maintaining galvanic isolation. Thermal management relies on a built-in air blower, which channels cabinet air across the heat sink to keep internal components within their operating range during cyclic loading. Fiber-optic communication also helps reduce the effect of electrical noise in industrial cabinets that contain switching devices and adjacent power modules. As part of the DIAX04 family, the unit shares the general platform used by related rack-mounted drive modules.
The unit is part of Line 03 and is identified as Version 1. As an HDS Drive Controller, it mates directly with HMS or HVE power supplies through standardized back-plane connectors, which keeps the rack layout straightforward. Status LEDs provide immediate operating feedback after power is applied, and the modular format reduces separate point-to-point wiring inside the rack. The controller is suited to packaging lines, printing presses, and material-forming stations that require coordinated multi-axis motion and stable response during repeated cycles.
