Product Description:

The HDS03.1-W075N-HS27-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It links the DIAX04 supply module with servo axes, supplying regulated current loops and velocity commands that keep multiple motors synchronized in industrial automation lines. By acting as the central axis interface, it forwards diagnostic and status data to higher-level PLC systems while coordinating precise motion profiles in packaging, printing, and handling equipment. Its modular layout allows the controller to work with separate supply and motor components rather than combining every function in one housing. This arrangement suits machines that require repeatable positioning, steady speed control, and fast reaction to load changes.

Communication with the host control system is handled over the SERCOS fiber-optic ring, enabling deterministic command cycles and real-time parameter access. The power stage can deliver up to 75 A of continuous output, so the unit can support demanding servo axes during sustained operation. Waste heat is removed by a built-in air blower that moves enclosure air across the heat sink and eliminates the need for external ducting. The housing has a protection rating of IP 10, which blocks solid objects larger than 50 mm but does not provide water protection. Rated operation is permitted in ambient temperatures from +5 to +45 °C, and additional panel cooling is needed outside this range to avoid derating. Because cooling depends on internal airflow, clear ventilation paths inside the cabinet help maintain stable thermal performance.

The controller retains its electrical ratings at elevations up to 1000 m above sea level, while operation above that height requires output current reduction. As ambient temperature approaches +55 °C, the unit must also be derated to protect power semiconductors. During storage or transit, it tolerates temperatures from -30 to +85 °C, allowing safe warehousing without climate control. An insulation system classified as C under DIN VDE 0110 supports high internal temperatures during continuous duty. Reduced air density at higher elevation and warmer cabinet conditions both limit heat removal, so these installation conditions directly affect available output.
