HDS03.1-W075N-HA38-01-FW
The HDS03.1-W075N-HA38-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for multi-axis racks, the unit regulates the current and velocity of synchronous or induction servomotors used in conveyors, tooling centers, and material-handling stations. By converting DC bus energy into controlled three-phase motor output, it closes the torque loop and sends operating status back to the machine control. This control behavior helps the connected motor follow commanded motion profiles while maintaining stable response under changing load conditions. Its rack-based format makes it suitable for automated motion systems that require repeatable axis response during acceleration, deceleration, and steady running.
The drive accepts setpoints through its command communication interface, which is configured as an analog ±10 V channel so the supervising controller can vary speed or torque without using a digital fieldbus. Thermal management is handled by a built-in air blower that pulls cabinet air across the heat sink, allowing installation inside enclosed electrical panels when cabinet airflow is available. During continuous operation, the power stage can supply up to 75 A of motor current, which suits medium-power axes that see frequent accelerations, reversals, or sustained process loads. The controller is part of the DIAX04 family, so it shares mechanical alignment and bus connection compatibility with matching supply modules in the same rack.
Model coding provides additional configuration data for the unit. The designation Line 03 places the controller in the third design line and identifies the revision used within this product family. The drive is Version 1, which marks the release assigned to this unit. These codes distinguish the controller from nearby revisions that may use different internal layouts while serving the same general application role.
