Product Description:

The HDS04.2-W200N-HT19-02-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in automation cabinets, it conditions DC-bus energy and executes motion commands to run servo and spindle motors in packaging machines, machining centers, and material-handling cells. The unit translates digital setpoints from a master control system into controlled current and voltage output so each connected axis can follow programmed position, velocity, and torque profiles. In multi-axis equipment, this allows the controller to respond quickly to changing load demands while supporting coordinated motion during acceleration, cutting, indexing, and transfer moves.

The controller exchanges real-time position, velocity, and diagnostic data through SERCOS, a fiber-optic ring that supports deterministic cycle times. Deterministic communication helps the drive apply synchronized updates at fixed intervals, which is important when multiple axes must start, stop, or interpolate together. Within the DIAX04 family, it is part of Line 04, matching the mechanical height and backplane connectors used by that generation. The power section delivers a continuous output of 200 A, which suits high-inertia axes and heavily loaded spindles. Thermal conditions are managed by a built-in air blower that moves cabinet air across the heat sink and exhausts it upward. Control words and parameters are transmitted through the command interface, which removes the need for analog reference wiring and helps reduce electromagnetic interference. Using a digital command path also simplifies signal routing inside the cabinet because reference values and status data travel on the same control connection.

The drive controller is Version 2. Classified as an HDS Drive Controller, it follows the diagnostic LED layout, fault-code structure, and parameter numbering used across the platform. This consistent arrangement keeps operating states and fault messages organized when the controller is used alongside related modules in the same cabinet. Its modular format also supports systems that use separate supply sections and cabinet-mounted companion modules, so the controller fits larger drive assemblies without requiring a standalone housing.
