HDS04.1-W200N-HA02-01-FW
The HDS04.1-W200N-HA02-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a key element in multi-axis systems, this unit supplies regulated power and motion commands to connected servo modules, enabling coordinated positioning and velocity control on assembly lines, machine tools, and packaging stations. By interpreting reference signals and closing the torque loop internally, the controller provides the electrical interface between the main power supply and the servo motor stages that perform the mechanical work. It is intended for applications that require stable axis response, repeatable speed control, and centralized drive hardware in a cabinet-based system.
One operational feature is its command channel, which accepts analog reference voltages from a master PLC or motion card, allowing real-time speed or torque setpoints without digital protocols. The controller belongs to the DIAX04 family, and thermal management is handled by a built-in air blower that draws cabinet air across the heat sink to keep semiconductor temperatures within limits during continuous duty. The power stage can deliver up to 200 A of continuous current, matching medium-to-high power servo axes that require strong acceleration and steady torque output. Its modular design allows it to be installed alongside companion drive components, which helps maintain a compact layout in multi-axis control cabinets.
The product is Version 1 and sits in Line 04 within the series hierarchy. It is identified as an HDS Drive Controller, which means it serves as the control and power stage for connected axes rather than as an independent machine controller. This unit works with separate motor stages that handle mechanical output, while the controller manages current delivery and axis regulation. In multi-axis systems, this layout supports synchronized motion across several axes without requiring each axis to use a fully separate control package.
