Product Description:

The HDS05.2-W300N-HA42-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Installed in a DIAX servo system rack, it acts as an axis-specific control module that modulates motor phase current from upstream reference signals. In industrial automation, it converts low-level motion commands into regulated power so conveyor sections, gantry axes, and forming tools can run with repeatable speed, torque, or position control. Feedback from the motor closes the loop and helps the axis maintain stable operation under changing load conditions. This arrangement suits applications that need consistent response during acceleration, steady running, and deceleration.

At the power stage, the controller supplies up to 300 A of continuous output current, allowing heavy-duty motors to accelerate without thermal cutback. Command data enters through an analog interface, and the unit accepts ±10 V or 0–10 V input signals that are converted to current setpoints inside the module. Heat is removed by a built-in air blower that draws ambient cabinet air across the IGBT stack, helping keep component temperatures within permissible limits. As part of the DIAX04 family, the controller uses the same back-plane pinout found across compatible axes. The unit is Version 2 and includes updated LED status channels for clearer operating indication.

The controller uses the 05 line footprint, matching the height of associated power supply modules in multi-axis racks. This common form helps keep cabinet layout orderly when several axes are installed side by side. The module is intended for closed-loop servo applications that require direct current regulation from a centralized rack system. Its position in the rack keeps power distribution and signal routing inside the enclosure, which supports a compact axis layout. The result is a control stage that fits high-power servo systems where stable current delivery and organized rack integration are required.
