Product Description:

The HDS03.2-W075N-HS43-02-FW is a modular drive controller manufactured by Bosch Rexroth Indramat. It belongs to the HDS Drive Controllers series. As a motion-control component, the unit forms part of multi-axis DIAX04 drive packages, where it regulates power delivery to servo and main spindle motors in automated production cells. In that role, it converts shared bus power into controlled motor current so connected axes can follow commanded torque and speed profiles during machine operation.

Behind the front panel, the controller communicates with higher-level CNC or PLC equipment through the SERCOS optical interface, which carries setpoint, status, and diagnostic data with uniform cycle timing. That communication method supports coordinated data exchange between the drive and the control system during synchronized motion. Current to the connected motor phases can reach a continuous level of 75 A, allowing the unit to support high-torque axes without external boost modules. Thermal energy from the power electronics is removed by a built-in air blower, so cabinet airflow remains easier to manage while the controller operates at its nominal rating. Internal forced airflow helps stabilize heat sink temperature during sustained load conditions. The model is part of the DIAX04 drive family, and the unit is classified as Line 03 in that platform.

This individual unit is Version 2, which indicates the second release level for this controller type. The controller mounts beside an HVR or TVM supply in Bosch Rexroth motion platforms, where it serves as the axis power stage within a modular cabinet arrangement. That placement keeps the power section close to companion supply units and supports orderly internal cabinet routing. It also accepts auxiliary plug-in cards without additional brackets, so option modules can be added directly at the controller. Enclosure dimensions, mounting rails, and bus connectors follow the established layout used for this product line, which keeps installation consistent across adjacent modules.
