HDS03.2-W075N-HS58-01-FW
The HDS03.2-W075N-HS58-01-FW is an industrial drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis system, this unit regulates current and velocity loops for servo drives and coordinates motion over the fiber-optic control bus. In automated machining centers, packaging lines, and material-handling stations, it functions as the central axis interface, translating motion commands into regulated armature currents so that connected motors follow programmed trajectories with repeatable accuracy. This allows precise axis response in coordinated production equipment.
The controller exchanges setpoints and feedback through the SERCOS interface, which avoids analog drift and provides deterministic communication timing for coordinated axes. Its output stage can supply a continuous current of 75 A, enabling the drive to energize large torque motors without external boosters. Thermal management is handled by a built-in air blower, which channels cabinet air across heat sink fins to keep semiconductor temperatures within acceptable limits during high-duty cycles. The unit belongs to the DIAX04 family, so it can share power supplies and encoder feedback buses with other axes in the same rack. The unit is part of Line 03.
The controller is Version 2. It automatically negotiates address assignments over SERCOS and reports topology faults to the PLC in a single status word. Internal diagnostics monitor blower speed and heat sink temperature, and the drive derates current if airflow drops. All control terminals and fiber connectors are located on the front edge, so signal connections remain accessible without disturbing bus bars or coolant ducting. This front-access layout also keeps fiber and control wiring reachable when adjacent modules are installed.
