Product Description:

The HDS03.1-W075N-HS12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series within the DIAX04 platform. This unit coordinates the power stage of multiple servo axes, acting as the interface between higher-level motion commands and the connected motors on a production line. By converting digital setpoints into regulated current flow, it enables precise velocity and torque regulation in automated machinery such as printing presses, packaging stations, and material-handling systems.

Communication with the central PLC is carried across the real-time SERCOS optical ring, so parameter data and diagnostic status are transferred at deterministic intervals. The power section can supply up to 75 A of continuous current, allowing it to drive medium-sized Indramat servo axes without external boosters. Internal thermal management is handled by a built-in air blower; this fan draws cabinet air through the heat sink to disperse heat generated during switching. The enclosure has an IP 10 rating, so installation is expected inside a closed control enclosure. Reliable operation is permitted in an ambient range of +5 ... +45 °C, so the unit can run under typical shop-floor conditions without derating.

Additional operating limits help the controller maintain electrical integrity in less favorable conditions. Continuous service is supported at elevations up to 1000 m above sea level; above this height, reduced air density may require power reduction. Windings and internal conductors meet thermal endurance class C as per DIN VDE 0110, permitting higher hot-spot temperatures than class B or F designs. When the equipment must be stored or shipped, the electronics tolerate temperatures between -30 ... +85 °C without performance loss. During operation, brief exposure up to +55 °C is permissible, although output current must be derated in that condition to prevent semiconductor overheating.
