HDS03.1-W100N-HS25-01-FW
The HDS03.1-W100N-HS25-01-FW is an industrial drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts commanded motion into regulated current for servo axes used in factory automation cells and machining centers. By linking the motor side to a common DC bus, the unit manages torque, speed, and position control so coordinated axes can operate with accurate timing. This control action helps the axis respond consistently to changing loads during acceleration, deceleration, and steady-speed operation. The controller is intended for cabinet installation alongside matching supply modules in centralized drive systems.
Communication with the higher-level control uses the SERCOS fiber-optic interface, which supports cyclic data exchange with deterministic timing. As a member of the DIAX04 platform, the module shares rack dimensions and bus connections with compatible system components. The controller can supply up to 100 A of continuous output current, and that current level supports motors that require sustained torque without immediate thermal derating under normal operating conditions. Heat is removed by a built-in air blower, which directs airflow across the heat sink without requiring external ducting. The designation Line 03 identifies the corresponding design line for this controller format.
The unit is classified as an HDS Drive Controller, indicating its role as a servo regulation module rather than a stand-alone power converter. It is listed as Version 1, which identifies the product revision used for this model. In a multi-axis rack, the controller works from the shared DC supply and passes controlled current to the connected motor while higher-level commands remain synchronized over the optical interface. The unit fits systems that separate supply hardware from the axis controller, so power conversion and motion regulation remain organized in dedicated modules.
