Product Description:

The HDS04.2-W200N-HS28-01-FW is an axis control module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed inside a modular drive stack, it receives real-time axis commands from a higher-level motion processor and modulates motor power so automated packaging, handling, or forming equipment can synchronize position and velocity across multiple servo axes. It interfaces with a power supply unit and motor modules through standardized backplane connectors, forming a closed current loop that helps reduce response time during dynamic load changes. This arrangement allows the controller to react quickly to command changes during indexing, acceleration, and shifting load conditions in coordinated machinery.

Its command interface is SERCOS, providing deterministic optical messaging for setpoints, feedback, and diagnostics at 2 or 4 Mbit/s. The unit belongs to the DIAX04 controller family, which uses consistent card dimensions and fieldbus wiring across the platform. Cooling is handled by a built-in air blower, so heat is expelled through the module’s top grill without relying only on cabinet ventilation. The power stage is rated for 200 A of continuous current, enabling the controller to drive high-inertia axes without derating. The unit is Version 2 and uses updated current measurement to reduce ripple during low-speed operation.

The device is part of Line 04, which indicates the line assignment used for this model within the series. It is an HDS Drive Controller, so it uses the service command structure common to related HDS units. A front panel serial port is provided for local communication without removing the housing. Its housing format matches the rack layout used by the series, allowing the module to fit alongside the required power supply and motor interface components. The rack-based format keeps power, communication, and axis electronics arranged in a single drive assembly, which supports compact installation in multi-axis cabinets.
