HDS03.2-W075N-HT40-01-FW
The HDS03.2-W075N-HT40-01-FW is a modular drive controller built by Bosch Rexroth Indramat for use in multi-axis automation racks. Within a motion system, it bridges the central power supply and the individual servo motors, translating digital command data into regulated current and voltage that control axis speed, position, and torque. By handling these closed-loop tasks, the unit supports precise, synchronized motion in machine tools, packaging lines, and material-handling cells. Its modular format also allows it to operate as part of a coordinated rack-based drive system rather than as a standalone controller.
Control data reach the module through the SERCOS optical interface, so time-deterministic setpoint and feedback telegrams can share a common fiber ring with other axes. Internally, thermal management relies on a built-in air blower that pulls cabinet air across the heat sink, eliminating external ducting and helping keep semiconductor junctions within safe limits. The power stage can deliver a continuous 75 A of motor phase current, and this continuous current level influences upstream fuse selection and available sustained motor output. The unit is part of Line 03, which uses the corresponding mechanical dimensions and connector layout across the rack. It also follows DIAX04 controller family conventions for parameter handling and rack integration.
The unit is Version 2 and uses updated gate drivers that tolerate higher switching frequencies while remaining compatible with earlier backplanes. It is classified as an HDS Drive Controller, and it uses the pinout and cooling arrangement of the HDS Drive Controllers series. This layout supports integration with HMS or HVE supply modules in the same rack and keeps the module aligned with the electrical interface used across the platform. The result is a controller that fits established multi-axis assemblies without requiring changes to the surrounding rack structure.
