HDS03.2-W100N-HS95-01-FW
The HDS03.2-W100N-HS95-01-FW is a closed-loop drive controller designed by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. As a servo axis module, it receives DC bus power from a compatible supply and sends precise current commands to connected motors for synchronized speed, torque, and position control in automated assembly lines, packaging equipment, and general-purpose machinery. Its role is to translate motion instructions from the machine control level into fast, accurate drive signals for individual axes. Because the controller closes the motor loop at the axis level, it can respond quickly to load changes during indexing, transfer, and positioning tasks. This arrangement also helps reduce cabinet wiring complexity and keeps the axis hardware grouped within the drive system.
Communication with higher-level controllers is handled over the SERCOS fiber-optic ring, which carries cyclic setpoints and diagnostic data at real-time bus speeds. That interface supports coordinated motion where multiple axes must follow synchronized commands from a central control system. The module is part of the DIAX04 automation family, so its parameter structure and backplane connectors match companion axis cards in the same rack. During operation, the power stage can deliver a continuous armature current of 100 A, so the connected supply and motor cabling must support that load. Heat from the IGBT bridge is removed by a built-in internal air blower that channels air through finned heat sinks without depending on external cabinet airflow.
The product is in Line 03, which corresponds to the third design line for this controller platform. It is Version 2, indicating updated gate-drive circuitry and expanded parameter memory compared with earlier releases. The function class is an HDS Drive Controller, matching the unit's role as a regulated servo axis module within a DC bus drive system. The line and version identifiers distinguish this model from earlier releases that used different internal electronics. It is used where a single axis must receive controlled current from the shared DC bus while remaining coordinated with the rest of the machine.
