Product Description:

The HDS03.2-W100N-HA28-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat. It interfaces between a central motion processor and individual servo axes, converting command references into controlled output current that maintains speed and position accuracy in automated machining centers, printing lines, and assembly stations. The integrated regulation and diagnostic functions allow the controller to react to load changes quickly while keeping axis behavior consistent during coordinated machine movement. Thermal management is built into the housing, so the unit fits dense multi-axis cabinets without requiring separate cooling hardware for each axis.

The unit receives setpoint information through an analog command interface, allowing simple voltage or current references from legacy PLCs to be used without additional fieldbus hardware. That input method is useful where existing control systems still provide conventional analog references instead of digital network commands. It belongs to the DIAX04 controller family, so it can be used with compatible power supplies and motor feedback modules in that platform. A built-in air blower moves cooling air across the heat sink, removing waste heat without relying on external cabinet fans. The continuous output capability is rated at 100 A, which is the maximum motor phase current the unit can deliver during sustained motion cycles.

The device is assigned to Line 03, so its mechanical dimensions and connector layout match other third-line HDS modules. That assignment also keeps placement within multi-axis racks consistent when several units are installed side by side. It is part of the HDS Drive Controllers series and is a drive controller, so it is used with external power supplies rather than an integrated mains rectifier. The product is Version 2, indicating the second release of this controller variant.
