HDS04.2-W200N-HT10-01-FW
The HDS04.2-W200N-HT10-01-FW is a digital drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. It installs in a DIAX04 multi-axis rack and converts DC bus energy into controlled three-phase output for servo motors. By regulating current and speed in real time, the unit supports coordinated motion commanded by a PLC or CNC in machine tools, pick-and-place gantries, and automated assembly equipment. It acts as the power and regulation stage for the connected axis, allowing the motor to respond smoothly to changing load conditions. Its vertical mounting format helps keep adjacent power supplies and feedback modules organized in a compact cabinet layout.
Communication with the higher-level control is handled through SERCOS, allowing deterministic fiber-optic data exchange between the controller and the motion system. The power stage is rated for 200 A of continuous motor current, which supports high torque demand during sustained operation and rapid acceleration. Thermal energy is removed by an internal air blower that forces air across the heat sinks, so no external ducting is required. The controller belongs to the DIAX04 family and is part of Line 04, which places it within the fourth design line of the platform.
The unit is Version 2, which identifies the second release of this model. Motion setpoints are received through the command interface, and the controller translates those inputs into regulated motor current and speed. This operating method allows the axis to follow commanded moves with consistent response during positioning and speed-controlled tasks. Because the controller processes commands inside the rack, it can be used on axes that require repeatable starts, stops, and speed changes across continuous duty cycles. In a multi-axis installation, the module works alongside the rack’s power and feedback sections to support coordinated machine motion.
