Product Description:

The HDS03.2-W075N-HT73-01-FW is a modular servo drive controller manufactured by Bosch Rexroth Indramat. It belongs to the HDS Drive Controllers series and is intended for coordinated motion in DIAX drive racks connected to CNC or PLC control systems. In operation, the unit regulates current and velocity loops for multiple axes so positioning tables, gantries, and printing lines can follow commanded motion profiles with stable response. Its modular format allows it to function as part of a rack-based drive system rather than as a stand-alone inverter. That arrangement supports compact multi-axis layouts in cabinets where several motion channels share a common platform.

Communication is handled through SERCOS, which provides deterministic optical data exchange for synchronized motion control. The controller delivers a continuous output of 75 A, giving it enough current capacity for medium-power servo motors used on demanding production equipment. Heat is removed by a built-in air blower that circulates cabinet air across the heat sink, so no external ducting is required for normal cooling. The unit is also part of the DIAX04 family, so it follows the interface style and system architecture used across that platform. This suits applications where coordinated axes must exchange commands quickly and maintain repeatable speed and torque behavior during changing loads.

The controller is identified as Version 2 and is assigned to Line 03. It uses standardized back-plane connectors for installation in common racks, which keeps the electrical connection method consistent across multi-axis assemblies. Classified as an HDS Drive Controller, the unit supports the core drive functions needed for closed-loop servo operation without requiring a separate stand-alone control section. Its rack-mounted format leaves room for matching supply and interface modules in the same enclosure. The modular housing and optical communication path support synchronized axis control in industrial cabinet systems.
