Product Description:

The HDS04.2-W200N-HT28-02-FW is a drive controller produced by Bosch Rexroth Indramat for modular motion systems. It belongs to the HDS Drive Controllers series, where individual axis modules are combined with matching power supplies to build multi-axis drive systems. In an automation cell, the unit receives digital motion commands and converts them into controlled power for servo motors, closing the loop between higher-level PLCs and mechanical motion elements. This arrangement lets several coordinated axes share a common supply structure while still giving each motor its own controlled output stage.

Motion commands arrive through the SERCOS fiber-optic interface, a deterministic serial bus that lets the controller exchange position setpoints and status words every cycle without additional wiring. The bus supports synchronized transmission of command values and operating feedback across the drive network. Hardware layout follows the DIAX04 platform, so the mechanical dimensions and connector pattern match companion modules on the same rail. The matching module format keeps mounting and front access consistent across the assembly. Thermal management is handled by a built-in air blower, so heat is removed actively from the housing and cabinet ventilation is simplified. The current stage is rated for 200 A, giving the controller headroom for high peak torque demands on large synchronous motors. The unit is part of Line 04, which supports the electrical and coordination features used for this axis class.

This unit is version 2, so parameter structures and diagnostic codes follow the second design release. The module occupies one slot in the rack and operates as a drive controller that exchanges real-time data over the bus while supplying controlled motor power. It is intended for use with matching supply modules in a cabinet-based multi-axis system rather than as an independent power source. Active cooling from the blower helps maintain internal temperature during continuous regeneration cycles.
