HDS05.2-W300N-HS03-02-FW
The HDS05.2-W300N-HS03-02-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As an axial module for the DIAX04 multi-axis platform, the unit supplies regulated power and motion commands to connected servo drives. By coordinating several axes through a common controller rack, it converts higher-level program instructions into controlled current and velocity profiles that keep industrial equipment synchronized during continuous operation. Its rack-based format suits machine layouts where multiple servo axes share a common power structure and require closely timed motion control.
Communication between the controller and drive modules takes place over the SERCOS optical ring, which supports synchronous data exchange with cycle times suited to high-speed interpolation. The unit is part of the DIAX04 family, so its backplane connectors mate with other modules that share power and diagnostic buses in the same rack. Thermal management relies on a built-in air blower, which maintains airflow around the heat-generating power stage without external ducting. The controller has a continuous output capability of 300 A, and this value is the rated current. The unit is part of Line 05, and its wiring and fuse selection must match that line designation.
The controller is classified as Version 2, and it adds updated diagnostic flags while remaining compatible with earlier motion libraries. This supports centralized axis control in production cells that require coordinated starts, stops, and speed changes across multiple drives. The optical link also carries parameter transfer and real-time axis status, so control data and operating feedback remain on the same fiber-optic loop. This arrangement helps the system maintain synchronized operation without separate communication wiring for routine status exchange.
