Product Description:

The HDS03.2-W100N-HA18-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts motion commands from a CNC or PLC into regulated current for connected servo motors so industrial axes can accelerate, brake, and hold position under controlled conditions. By combining power electronics, logic processing, and diagnostics in a single chassis, the unit helps simplify multi-axis cabinet layouts used on machining centers, packaging lines, and material-handling systems. This arrangement lets the controller serve as the regulation stage for a machine axis while higher-level control remains in the host system.

The controller accepts a ±10 V reference through its ANALOG command interface, allowing real-time velocity or torque control from compatible host units without protocol conversion. That interface is useful in systems where the master outputs a continuous command signal rather than digital network data. Its power stage is rated for 100 A continuous output, giving medium-power servo axes sustained current capacity during demanding cycles. Component temperatures are managed by a built-in air blower that channels enclosure air across the heat sink, so no external fan tray is required. Mechanical and electrical integration follows the DIAX04 platform, which keeps the controller matched to that rack architecture.

The unit is part of Line 03 and is listed as Version 2. It is an HDS Drive Controller, which distinguishes it from separate supply or communication modules in the same drive system. This revision keeps the established analog command structure while adding expanded diagnostic reporting, so operating status and fault conditions can be identified more clearly during use. The line and version information identify the controller generation used for this model and indicate its place within the product range.
