HDS03.2-W075N-HA23-01-FW
The HDS03.2-W075N-HA23-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for cabinet mounting, the device links to a shared DC bus and works with servo power stages to supervise motor speed, torque, and position in automated equipment. Within an industrial cell, it accepts operating setpoints, performs closed-loop calculations, and issues high-frequency switching signals for synchronized motion on packaging lines, assembly robots, and metal-cutting spindles. This layout keeps control and power functions organized within a common rack structure.
The module exchanges setpoints through an analog command interface, so a ±10 V reference from the PLC is translated directly into drive current demand. Because it belongs to the DIAX04 controller family, it uses the same back-plane dimensions and bus connectors found across that platform. A built-in air blower pulls cabinet air across the heatsink, removing semiconductor heat without external ducts and permitting vertical stacking of several units. Power electronics are rated for a continuous output of 75 A, giving margin for high-inertia axes that experience heavy acceleration and repeated load changes. The unit is part of Line 03, which identifies the third design line.
The unit is Version 2, indicating a later revision while keeping the same field wiring points. Functionally, it is classified as an HDS Drive Controller, occupying the link between the supply converter and the motor. The upstream CNC or PLC remains responsible for motion profiling and command generation. The module focuses on current regulation, speed correction, and position response for the connected axis. Its role centers on turning low-level command signals into regulated switching behavior at the motor output stage.
