Product Description:

The HDS03.2-W075N-HT76-02-FW is a drive controller module produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It occupies the power section of a DIAX04 motion cabinet and channels energy from a regulated DC bus to connected servo drives. Within an automated cell, the unit coordinates torque, speed, and positioning commands so that multiple axes follow synchronized motion profiles in CNC, packaging, or material-handling systems. This arrangement allows the cabinet to support coordinated motion functions while keeping the drive hardware consolidated in a rack-based format.

The controller exchanges real-time setpoints with the master control through the SERCOS fiber-optic ring, which supports deterministic communication between the control and drive system. The unit provides up to 75 A continuous output current. Thermal management relies on a built-in air blower that moves cabinet air across the heat sink fins, so external ducting is not required. The unit belongs to the DIAX04 family, so it matches the cabinet dimensions and interface arrangement used in related slots. This communication and cooling layout supports stable operation in multi-axis systems that require synchronized command updates and sustained current delivery.

The module is part of Line 03 and is built as Version 2. These identifiers keep the product generation clear within a multi-axis rack and help maintain compatibility with the intended interface boards and rack layout. The internal cooling path is sized for the module’s output section, and the drive can share the same DC bus and fiber-optic network with adjacent compatible units. When installed beside matching drives, it supports a uniform cabinet arrangement without additional repeaters, which helps preserve orderly rack integration in larger motion systems.
