Product Description:

The HDS04.2-W200N-HT25-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is intended for cabinet installation in multi-axis machining centers, printing presses, and assembly lines where tightly regulated servo motion is required. The unit receives setpoint data from a higher-level motion processor and converts it into controlled motor current for the connected axis. This lets the controller link numerical motion commands to the mechanical load with fast response and stable regulation. Its role is to serve as the power stage between the motion control system and a compatible servo motor. In automated equipment, this type of controller is used where rapid changes in torque and speed must be tracked without loss of position quality.

As a Line 04 device, the module follows the mechanical and electrical layout used in the early DIAX platform. The unit is Version 2, which supports later command structures and more detailed diagnostic handling. Communication with the automation controller takes place over the optical SERCOS interface, allowing deterministic real-time data exchange and synchronized cycle timing. The optical link also helps maintain signal quality in electrically noisy machine cabinets. Thermal control is handled by a built-in air blower that moves cooling air across the heat sinks without external ducting. The power section is rated for a continuous output of 200 A, allowing the controller to drive large torque motors and other high-demand servo axes while staying within thermal limits.

This unit is part of the DIAX04 platform, so it uses the status handling and parameter structure associated with adjacent axes in the same rack. It is classified as an HDS drive controller, so its control functions are focused on position and velocity regulation rather than spindle operation. That focus suits axes that perform point-to-point moves and interpolated paths in coordinated systems. The module uses standardized backplane connectors and a shared power bus for integration in multi-axis assemblies. This arrangement supports coordinated cabinet layouts and consistent electrical interfacing across neighboring drive positions.
