Product Description:

The HDS03.2-W075N-HS37-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a digital axis unit, it links servo drives with centralized motion systems and provides closed-loop regulation for positioning and speed tasks in automated machinery and transfer lines. The modular format allows it to operate as part of a larger drive assembly rather than as a standalone power package. In coordinated systems, the controller processes command values from the motion control and translates them into regulated motor output for repeatable axis movement. That makes it suitable for axes that must accelerate, decelerate, and hold speed under varying mechanical load.

The controller exchanges setpoint and diagnostic data over the SERCOS fiber-optic bus, allowing deterministic coordination with other axes on the ring. It belongs to the DIAX04 multi-axis platform, so parameter handling follows the conventions of that architecture. Electrical output is rated at 75 A, which suits medium-power servo motors used on packaging, printing, and material-handling stations. The unit is part of Line 03, the third design line in this product range, and it uses the connector layout and backplane pinout assigned to that revision. Because communication is cyclical and time-synchronized, multiple drives can respond to shared control commands without irregular timing between axes.

Thermal management is handled by a built-in air blower that draws cabinet air over the power semiconductors during high-duty cycles. The motion card uses Version 2 of the backplane design, which corresponds to the second revision used for this controller. The unit is classified as an HDS Drive Controller, indicating its interface format within the product range. Forced internal airflow helps maintain thermal stability when the controller is installed beside other power modules in densely populated cabinets. The controller is intended for systems that separate the power infrastructure from the axis module to keep the drive layout modular.
