Product Description:

The HDS05.2-W300N-HT20-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series within the DIAX modular automation platform. This controller supplies regulated DC bus energy to servo or main-spindle inverters and supervises their performance in multi-axis production lines, machining centers, and handling systems. In operation, it regulates current delivery so commanded torque and speed remain stable during acceleration, cutting, and positioning tasks. This role makes it suitable for machine sections where several coordinated axes must respond to synchronized commands from a CNC or motion PLC. It forms part of the power section in a rack, where it uses DC bus power and exchanges real-time status information with higher-level motion processors through its integrated communication interface.

The command channel uses the fiber-optic SERCOS interface, allowing deterministic cycle times and strong immunity to electrical noise between the motion controller and the drive. Because the command path is optical, signal quality is less affected by switching noise from nearby power electronics. A continuous output capability of 300 A enables the unit to supply high-torque motors or several smaller axes that share a common DC link. Thermal management is handled by a built-in air blower, which removes heat from the heat sink without external ducting and supports stable operation in dense control cabinets. The unit is part of Line 05, and its control logic matches the architecture of the DIAX04 family.

The unit is Version 2. It can be combined with HVR power supplies and HMS feedback cards to complete a closed-loop servo package, and that modular layout separates supply, feedback, and axis functions into dedicated rack components. This arrangement suits multi-axis installations that use shared power infrastructure while keeping feedback processing in its own module. It also supports cabinet layouts that distribute power conversion and axis control across adjoining modules instead of placing every function in one housing.
