Product Description:

The HDS03.1-W075N-HS95-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as the power and control stage between a motion-control host and AC servo motors, translating digital setpoints into regulated motor currents. Integrated monitoring circuits protect the drive against overcurrent and thermal overload during continuous operation. The controller is intended for coordinated axes that require repeatable torque and speed control in automated machining centers, pick-and-place systems, and handling equipment. Its modular format also supports installation in multi-axis racks where several drives share a common system layout. The unit also manages current delivery for closed-loop servo response during changes in load and speed.

Motion commands reach the unit over the SERCOS fiber-optic interface, which supports deterministic timing and simple daisy-chain wiring across the drive rack. The optical link also reduces susceptibility to electrical noise inside the cabinet. Within the DIAX04 controller family, this model is part of line code 03 and version 1. Thermal losses are removed by a built-in air blower, which helps maintain internal temperature while the drive delivers its rated output current of 75 A. The enclosure is rated IP10, which blocks solid objects larger than 50 mm while keeping airflow paths open for the cooling system. This arrangement suits cabinet installations where controlled internal airflow is available and direct contact with energized parts must be limited.

Continuous operation is permitted up to 1000 m above sea level, and output current must be reduced at higher elevations to limit thermal rise. The ambient operating range is +5 to +45 °C, and operation up to +55 °C is allowed when additional cooling air is provided. This extra cooling allowance helps in cabinets that run warmer under heavy-duty cycles. During shipping or storage, the electronics tolerate temperatures from -30 to +85 °C. Class C insulation and DIN VDE 0110 compliance support electrical isolation under these conditions.
