HDS04.1-W200N-HS91-01-FW
The HDS04.1-W200N-HS91-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Integrated into a multi-axis motion system, it coordinates power delivery and motion commands between servo inverters and a central PLC. The unit converts DC bus energy into regulated three-phase output for industrial servo motors, providing precise positioning and speed control on automated machine tools, packaging lines, and material-handling gantries. In these systems, the controller serves as the power stage that helps each axis respond smoothly to commanded acceleration, deceleration, and holding demands during normal machine cycles.
The controller can supply a continuous output of 200 A, which is the maximum RMS current available to connected axes without exceeding thermal limits. Command data are exchanged over SERCOS, an optical ring that supports deterministic real-time communication with higher-level devices and keeps motion updates synchronized across the control network. Heat is removed by a built-in air blower, which circulates cabinet air across internal heat sinks and removes the need for a separate external fan tray. As part of the DIAX04 family, the unit shares mechanical dimensions and connector layout with related modules. The unit is Version 1, which identifies this controller revision within the product line.
The product is part of Line 04, which places it in a power range suited to medium-to-high inertia servo axes on multi-kilowatt machinery. A consistent back-plane layout shared with other DIAX modules allows direct installation on the common rail and supports orderly DC-bus and signal routing inside the enclosure. The same housing uses mounting hole patterns that help preserve spacing between adjacent modules and simplify panel arrangement in dense drive cabinets. This layout is useful in multi-axis systems where several drive components are mounted close together and clear cable paths are needed for reliable cabinet organization.
