HDS04.1-W200N-HS54-01-FW
The HDS04.1-W200N-HS54-01-FW drive controller is built by Bosch Rexroth Indramat for the HDS Drive Controllers series. It fits into a modular multi-axis platform and forms the power stage between the supply module and compatible synchronous or asynchronous servo motors. In machine tools and material-handling cells, the unit closes the torque loop so connected axes can maintain accurate velocity regulation and coordinated motion. This allows several axes to respond quickly to command changes during synchronized machine movement. Because the power stage and control section are combined in one module, the drive can regulate motor behavior directly from higher-level motion commands.
The controller communicates through the SERCOS fiber-optic interface, so setpoint data and diagnostic information can be exchanged in real time while remaining electrically isolated from power wiring. It supports continuous output up to 200 A, making it suitable for axes that need sustained motor current under heavy load. Thermal management is handled by a built-in air blower that moves cabinet air through the heat sink and removes the need for external ducting. As part of the DIAX04 platform, it uses a shared connector arrangement and plug-in card format that help keep cabinet layouts consistent across related modules. The optical link also helps reduce the effect of electrical noise in cabinets with high switching currents.
The W200N subtype identifies this output class within the product line and distinguishes it from lower-current units in the same platform. The controller is assigned to Line 04, which places it within a specific grouping in the HDS range. It is released as Version 1, indicating the initial model revision. The coding used on this unit helps separate it from other HDS controllers that may use different current capacities, interfaces, or cooling methods. This keeps the model identification clear when multiple drive controllers are installed in the same cabinet.
