Product Description:

The HDS03.2-W075N-HA25-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series used in DIAX04 multi-axis motion systems. Serving as the closed-loop axis regulator between a supply module and a servo motor, it receives command values from higher-level controls and adjusts motor current to maintain accurate speed and torque response during dynamic motion. This makes it suitable for machining cells, material-handling gantries, and other automated equipment that requires coordinated axis control with repeatable motion behavior. The module mounts vertically in a control cabinet and links to neighboring units over a shared DC bus.

Its command channel uses an analog interface, letting PLCs output ±10 V references that the control section converts into digital setpoints for the current and speed loops. A rated continuous output of 75 A provides enough current for medium-to-large permanent-magnet motors while keeping the power section within its intended operating range during continuous use. Heat is removed by a built-in air blower that circulates cabinet air through the heat sink fins without external ducting. Because the cooling air stays inside the cabinet path, the installation can remain compact and does not require separate blower hardware on the outside of the drive.

The product is part of Line 03 within the series and is identified as Version 2. Classified as an HDS Drive Controller, it regulates motor current in real time and supports closed-loop operation for servo axes that must respond quickly to changing load conditions. Status and fault information are available through front indicators and service connections, so the operating state can be checked directly at the unit during normal operation. Its cabinet-oriented layout matches the modular arrangement used in HDS racks, so it fits cleanly into multi-axis drive assemblies.
