Product Description:

The HDS03.2-W075N-HS72-02-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As an axis module, it works with a central supply to control servo power stages in automated machinery. In packaging lines, machine tools, and material-handling cells, the unit closes torque and velocity loops for connected motors while exchanging setpoints and feedback with a PLC. This supports accurate speed regulation and responsive torque control during changing loads. It also uses local diagnostics, parameter memory, and field-oriented current regulation to support stable operation in multi-axis cabinets.

The command channel relies on SERCOS fiber-optic communication, allowing deterministic data exchange for synchronized motion control. Within the DIAX04 platform, the module connects to a common power supply and can share DC-bus energy during braking. Thermal management is handled by a built-in air blower, so heat is removed directly from the heat sink without external ducting. The internal airflow path directs heat away from the power section and supports continuous operation in compact rack assemblies. The power stage supports a continuous output of 75 A, which suits medium-frame servo motors during rapid acceleration or counter-torque demands.

The unit is part of Line 03 and carries Version 2. These identifiers indicate the product generation used for this controller type. Real-time monitoring of current, voltage, and temperature is processed locally and can be passed through the control network for drive diagnostics during operation. The module follows the connector spacing and rack layout used across this drive family, which helps it fit standard multi-axis installations. Its layout is intended for modular cabinet assemblies where several axis controllers are installed beside a shared supply unit.
