Product Description:

The HDS03.2-W100N-HS57-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cabinet, this unit coordinates torque, speed, and position commands for servo axes in multi-axis systems. It accepts setpoint data from higher-level motion processors and regulates power to connected motors so that industrial machinery can follow precise movement profiles. Because it manages both power delivery and motion response, it serves as the link between the cabinet power system and the motor connected to the axis.

A fiber-optic SERCOS interface serves as the command channel, allowing synchronous setpoints, diagnostics, and parameter data to move between the controller and the central motion card. The power stage has a rated current of 100 A, so it can energize large synchronous or asynchronous motors without exceeding thermal limits. Heat generated by the switching devices is removed by a built-in air blower, which circulates cabinet air across the heat sink and avoids the need for external fans. As part of the DIAX04 family, the unit shares bus cabling, encoder feedback connectors, and mounting dimensions with other drive modules in that platform. This layout helps the controller fit cleanly into established cabinet arrangements without requiring a separate cooling assembly.

The product is part of Line 03, which identifies its place within the product line. The unit is Version 2, indicating the second version used for this controller type. It uses common DC bus rails to interface with adjacent modules, and guided airflow paths direct the blower stream from the baseplate to the exhaust grille without obstructing nearby electronics. The mechanical interface remains compatible with neighboring rack modules in the same cabinet, and the airflow path helps move heat away from surrounding components.
