HDS03.1-W075N-HA42-01-FW
The HDS03.1-W075N-HA42-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. It regulates servo axes in multi-axis machining centers, packaging lines, and other automated equipment where coordinated torque and velocity loops must be processed quickly and repeatably. As a modular unit, it installs beside matching power supplies in a DIAX rack so that motion commands from a central PLC can be translated into precise motor currents. This arrangement supports machines that use several coordinated axes and require compact cabinet integration.
This controller exchanges set points over an analog command interface and expects ±10 V reference signals rather than digital fieldbus telegrams. A continuous output capacity of 75 A equips the module for medium-power servomotors that need strong acceleration without overheating the power stage during normal operation. Thermal management is handled by a built-in air blower, and the integrated fan pulls cabinet air through the heat sink fins so no external ducting is required. The analog control path suits systems that use voltage-based motion commands, while the current rating supports repeatable axis performance in demanding production cycles.
The unit belongs to the DIAX04 controller family and is part of Line 03, which matches the mechanical footprint used by other third-generation DIAX components. The controller is Version 1, and its dedicated diagnostic LEDs provide clear fault indication during operation. Its consistent mechanical coding and terminal layout support use with compatible transformer, mains filter, and motor feedback modules in the same platform. These platform traits help keep cabinet layouts orderly and maintain a straightforward connection structure for multi-axis drive assemblies.
