Product Description:

The HDS03.1-W075N-HA16-01-FW is a drive controller produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As a member of the DIAX04 motion control family, the unit provides closed-loop axis control and regulated drive power for servo systems used in multi-axis machinery. It occupies a slot in a common supply rack and exchanges reference values and feedback with higher-level PLCs, enabling coordinated positioning, speed, and torque functions in automated assembly lines and machining centers. This arrangement allows multiple axes in the same machine to respond together during coordinated motion sequences.

The controller accepts motor demands through an analog command interface, so velocity or torque setpoints arrive as ±10 V signals that the internal processor converts into pulse-width-modulated drive outputs. The controller has a rated current of 75 A, giving sufficient headroom for medium-power servo axes without triggering thermal limits. Temperature control relies on a built-in air blower, which pulls cabinet air across the heat sink and keeps semiconductor junctions below their limit in duty-cycle applications. The unit operates within an ambient range of +5 to +45 °C, while enclosure protection is limited to IP 10, so it must be mounted in a closed electrical cabinet.

At temperatures above +55 °C, the output current is derated, so loads must be reduced or panel cooling must be improved when that threshold is reached. During storage and transport, the electronics withstand -30 to +85 °C without functional damage, which supports shipment and warehousing in varied climates. The design tolerates installation heights up to 1000 m above sea level without adjustment, which matches the majority of industrial plants. Windings and dielectric spacing meet insulation class C under DIN VDE 0110, allowing higher internal temperatures than class B or class F components.
