HDS03.2-W075N-HA05-01-FW
The HDS03.2-W075N-HA05-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for use in the HDS Drive Controllers series. It occupies one slot in a multi-axis drive rack and supplies regulated power to servo motors used in packaging lines, machine tools, and material-handling equipment. By combining power electronics with closed-loop control, the unit converts DC bus energy into precisely timed phase currents that follow programmed motion profiles. In coordinated motion systems, it regulates motor current so commanded speed and torque changes can be applied with stable axis response.
This controller communicates through an analog command channel, enabling direct ±10 V speed or torque references from the master control. This arrangement allows the unit to respond to external reference signals without requiring a digital command interface. During operation, it can deliver up to 75 A of continuous output current, so it is suited for medium-power axes that need high acceleration without derating. Thermal management is provided by a built-in air blower, which forces air across heat-sink fins to keep semiconductor temperatures within permissible limits even when the unit is mounted inside a sealed cabinet. The controller belongs to the DIAX04 family and is part of Line 03.
The configuration reported here corresponds to Version 2, which uses updated internal circuitry for current sensing and monitoring. Classified as an HDS Drive Controller, the unit connects to the DC supply, motor power, and feedback conductors through keyed front sockets. This front-access layout keeps the main electrical connections at the module face for organized cabinet wiring. The module also clips into the same backplane used by other controllers in the range, allowing consistent installation within a multi-axis rack.
