Product Description:

The HDS03.2-W075N-HS04-02-FW is a multi-axis drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. As a rack-mounted module, it coordinates servo drives and related power modules so that motion control functions are handled from a central location in the drive cabinet. This arrangement allows one controller section to manage multiple coordinated drive functions inside a common rack architecture. It supports coordinated motion, speed regulation, and torque limiting in industrial machining cells, printing lines, and material-handling zones where several axes must respond to synchronized commands across the same automation system.

This controller exchanges real-time setpoints and feedback over the SERCOS fiber-optic bus, which permits deterministic cycle times and stable communication between the drive rack and remote motion processors. Continuous output capability is rated at 75 A, giving the unit enough current headroom for medium-power servo axes without the use of an external booster stage. Thermal management relies on a built-in air blower that draws cooling air through the card cage, reducing the need for separate cabinet-mounted fans. The unit belongs to Line 03 and is assigned Version 2, which identifies the design line and product version used for this controller.

Within the DIAX04 family, the device is registered as an HDS Drive Controller. This classification keeps its parameter files, cooling behavior, and SERCOS telegram structure aligned with the assigned product version, helping the controller operate consistently in modular multi-axis racks with shared system resources. The controller is intended to work with separate power supplies and regenerative units, so the drive system can be arranged around a centralized control stage rather than a standalone single-axis layout. The layout supports organized distribution of control, power conversion, and regeneration functions within the same cabinet.
