Product Description:

The HDS03.2-W100N-HS12-HS12-01-FW is a modular axis controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. It belongs to the DIAX04 automation platform and is identified there as line 03, version 2. The unit regulates servo drives and peripheral power modules in multi-axis machinery, providing closed-loop current and velocity control for coordinated motion tasks on factory-floor equipment. As part of a SERCOS-based system, it links motion commands from the supervisory PLC to the attached motors, forming the electrical interface between high-level control logic and electromechanical actuation.

The electrical envelope is anchored by a continuous output rating of 100 A, allowing the controller to feed large synchronous or induction motors without external boosters. Its housing meets the IP 10 rating under DIN 40 050, so it provides touch protection while leaving ventilation openings available for airflow. Real-time setpoints and status data pass through the fiber-optic SERCOS interface, which supports deterministic communication with other DIAX04 modules. Thermal dissipation is handled by a built-in air blower that draws cabinet air across the heat sinks, eliminating the need for auxiliary fans. For dielectric strength, the power section uses Class C insulation in accordance with DIN VDE 0110, supporting elevated temperatures during high-duty cycles.

The controller operates reliably between +5 to +45 °C, and its output can be linearly derated when ambient air rises to +55 °C. Altitude capability extends to installations at or below 1000 m, maintaining full current capacity without additional cooling correction. During shipping or warehouse storage, it withstands temperatures from -30 to +85 °C without damage to its operating characteristics. These limits allow the unit to be used in standard industrial cabinets where ambient temperature and installation height remain within the stated range.
