HDS04.2-W200N-HS77-00-FW
The HDS04.2-W200N-HS77-00-FW is a modular drive controller engineered by Bosch Rexroth Indramat for the HDS Drive Controllers series. It forms a bridge between cabinet-level power supplies and servo axes, converting command data into regulated motor currents for accurate motion profiles in packaging lines, printing presses, and material-handling systems. Power electronics, signal processing, and diagnostic functions are combined in one rack-mount unit, which helps reduce panel complexity in multi-axis installations. Integrated diagnostic logic allows operating states and faults to be monitored from the same controller housing.
Communication with higher-level CNC or PLC systems is accomplished through the SERCOS fiber-optic interface, which provides deterministic, collision-free telegrams for synchronized motion groups. The controller is rated for a continuous output of 200 A, making it suitable for large torque motors that draw substantial current during acceleration and sustained load. Thermal management relies on a built-in internal air blower, and this fan channels enclosure air across the heat sinks without requiring external ducting. As part of the DIAX04 family, the unit mounts on a common backplane that distributes the DC bus and enables signal exchange among adjacent amplifiers. This communication method keeps timing consistent across grouped axes during coordinated motion. The product is Version 2.
The mechanical format complies with Line 04, so its width, terminal spacing, and locking rails match other fourth-generation modules in the rack. Shared bus rails allow neighboring drives to exchange power without extra wiring, which helps keep cabinet routing orderly and reduces the number of separate connections between modules. The controller is intended for high-current servo axes that require stable current control and coordinated operation with nearby units in the same enclosure. Its standardized layout also helps the module align with adjacent drives on the rack rails.
