HDS03.1-W100N-HT04-01-FW
The HDS03.1-W100N-HT04-01-FW is a modular axis module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed beside a shared supply unit, it conditions power for one servo or spindle motor, monitors feedback, and exchanges status data with higher-level automation so motion profiles are carried out accurately in manufacturing equipment. This arrangement supports coordinated motion in machine tools, handling systems, and other equipment that relies on closed-loop axis control. Its modular format lets the drive operate as one axis within a multi-axis cabinet without requiring a dedicated supply section in the same housing.
Continuous output capability reaches 100 A, allowing the unit to energize high-torque axes without external booster cards. At this output level, the power section can support sustained torque demand during acceleration and process load changes. Command and diagnostic traffic moves over the optical SERCOS ring, which provides deterministic data exchange and galvanic isolation between the drive cabinet and the supervisory controller. As part of the DIAX04 family, the module uses the same general communication structure and mechanical format found across related controllers. Heat generated by the power electronics is removed by a built-in air blower, and the drive monitors airflow so a fault can be issued if ventilation drops.
This device is classified as an HDS Drive Controller. It is part of Line 03 and is built as Version 1, which identifies the product generation used for this model. These identifiers set the expected geometry and connector arrangement for the module in the rack. The unit is intended for use with a shared supply architecture, where each controller handles one motor axis while feedback and control data remain integrated within the drive. This keeps the axis module focused on motor control, current regulation, and operating status within the larger drive system.
