HDS03.2-W075N-HT71-01-FW
The HDS03.2-W075N-HT71-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Within a DIAX04 multi-axis platform, it supplies controlled torque and speed to industrial servo motors used on presses, handling units, and machining centers. By converting incoming DC bus energy into three-phase output, it supports accurate motor current regulation during acceleration, steady running, and position correction. The controller functions as an intelligent axis channel with closed-loop axis control, so commanded motion can be carried out with continuous feedback from the connected system components. This operating method helps the drive respond to load changes without losing synchronization with the machine cycle.
The controller operates with a continuous output capacity of 75 A, allowing it to drive medium-power servo axes under nominal ambient conditions. Thermal management is handled by a built-in air blower that circulates cabinet air across the heat sink, so no external ducting is necessary. Forced airflow helps keep the internal power section within its intended temperature range during sustained current demand. Command and diagnostic data reach the unit over a SERCOS fiber loop, which supports deterministic telegram timing for coordinated multi-axis motion and stable response between axes. Within the DIAX04 platform, the controller shares a common power supply and feedback architecture with drives installed in the same rack. The unit is part of Line 03 in the series.
The controller is Version 2. Its rack-style housing uses a consistent wiring layout and includes option slots for functions required by the application. This arrangement helps keep power and control connections organized inside multi-axis cabinets and supports orderly integration with matching system modules. The front-mounted connection layout also makes the unit easier to place alongside other drive components in the same enclosure. The unit is classified as an HDS Drive Controller.
