Product Description:

The HDS04.2-W200N-HS77-00-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within multi-axis DIAX modular systems, this unit manages power to servo drives, enabling coordinated motion tasks common in packaging lines, printing presses, and material-handling cells. By processing set-point data and issuing gate commands, the controller acts as the central regulation element that links motion requirements from a PLC to the power modules that energize individual motors. It is suited for applications that require synchronized acceleration, deceleration, and position control across multiple servo axes.

The control section exchanges cyclic set-point, status, and diagnostic data through the SERCOS fiber-optic bus, allowing deterministic communication in synchronized axis groups. Current delivery capability reaches 200 A, so the device can govern large-torque motors without external booster stages. Thermal management relies on a built-in internal air blower, which forces air across the heat-sink channels to keep semiconductor junctions within their safe operating area during continuous duty. The unit belongs to the DIAX04 controller family and is Version 2. Because command, status, and diagnostic information are exchanged over the same real-time interface, the controller can respond quickly to changing load conditions and coordinated motion sequences.

Product coding also specifies Line 04, which places the unit in the fourth design line with matching physical dimensions, mounting rail height, and connector layout. As an HDS Drive Controller, the unit integrates gating logic, communication hardware, and protective monitoring in a single enclosure. This arrangement reduces panel space compared with separate amplifier and gateway modules. Housing these functions together also reduces internal cabinet wiring and keeps the system layout more compact.
