Product Description:

The HDS03.2-W100N-HA23-01-FW is a modular control unit manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cabinet, it serves as the command and power interface between a motion controller and the servo drives that actuate individual machine axes. By translating high-level setpoints into regulated DC bus energy and switching commands, the module helps coordinate precise speed, torque, and positioning tasks in packaging lines, material-handling gantries, and similar multi-axis systems. In a multi-axis layout, it links the higher-level control system to the power electronics that drive each connected motor. Its compact Euro-card format fits cabinet layouts where control electronics and power modules must share limited panel space.

The controller receives setpoints through an analog command interface, so an external controller can send velocity or torque references as ±10 V or 4–20 mA signals that are converted into internal control values. This input method suits systems that use continuous reference signals instead of network-based motion commands. Heat from the power section is removed by a built-in air blower, allowing continuous operation without external ducting. The unit can deliver a sustained output of 100 A, so supply conductors and bus bars must be sized for that current. The product is part of Line 03, which indicates its design line within the series. It is also associated with the DIAX04 platform and uses the backplane arrangement common to that system.

The unit is Version 2. The internal designation W100N marks the controller’s power class. It works with supply modules and neighboring axes through the shared backplane, which helps reduce cabinet wiring density inside the drive rack. The module is intended for coordinated servo applications where stable current regulation and direct analog command input are required. Its rack-based layout keeps control and power connections organized within the cabinet.
