HDS04.2-W200N-HS22-01-FW
The HDS04.2-W200N-HS22-01-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. The unit acts as the central regulator for servo axes in automated machining cells and material-handling stations, converting motion commands from higher-level PLCs into precisely timed current and velocity setpoints for connected motor modules. In an automation rack, it distributes DC bus power, monitors feedback, and triggers protective shutdowns when load or temperature limits are exceeded. That makes it suitable for coordinated motion systems where stable regulation and fault monitoring are both required during repeated production cycles.
Its real-time data path uses SERCOS as the command communication interface, carrying position words, diagnostics, and synchronization telegrams over fiber-optic cabling for deterministic coordination with peer drives and controllers. This arrangement lets the control system exchange motion data and status information in a fixed timing pattern across multiple axes. Thermal management relies on a built-in air blower that forces air across internal heat sinks and keeps component temperatures stable without external ductwork. The power stage sustains a continuous output of 200 A, which supports large torque transients from high-inertia servomotors while remaining within the rated current range. This output level also affects conductor sizing and the protective trip points used with the associated mains supply.
The controller is part of the DIAX04 family, which uses the same fiber-optic bus structure across related motion modules. Within that family, it is assigned to Line 04, and this line uses connector geometry that mates directly with standardized backplane power rails. Hardware Version 2 uses faster A/D converters, allowing tighter loop timing and better velocity response during changing load conditions. This update speed is useful when the axis must respond to rapid command changes or shifting mechanical load.
