Product Description:

The HDS03.2-W075N-HT40-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is intended for use in multi-axis automation racks, where it regulates current, velocity, and position loops for connected servo axes. Within an industrial line, it links the power section with higher-level motion control so coordinated machine functions can run through a standardized command structure. That role allows a central controller to manage acceleration, speed regulation, and positioning across several axes in packaging, handling, or machining equipment. Its modular format also suits cabinet layouts in which multiple drive components are installed side by side.

This model communicates through the SERCOS fiber-optic interface, allowing synchronous cyclic data exchange with compatible control hardware. It provides a continuous output current of 75 A, so the connected motor and load must remain within that current range during operation. The fiber-optic link supports precise timing for motion commands and status data between the rack and the control system. Heat from the power electronics is removed by a built-in air blower, which moves cabinet air across the heat sink and removes the need for external ducting. This cooling method supports stable operation in enclosed control cabinets when sufficient airflow is available.

The unit is part of the DIAX04 platform and is assigned to Line 03, so its backplane, connector, and mounting dimensions follow that product line. It is identified as Version 2, which distinguishes this controller revision within the range. As an HDS drive controller, it shares electrical and mechanical compatibility with related modules used in the same system, including common bus bars, power supplies, and cooling zones. The shared platform layout helps the controller fit into established system assemblies without changing the basic arrangement of adjacent modules. That arrangement supports integration with matching power sections and rack hardware already used in the same installation.
