The Bosch Rexroth drive controller R911289532 (DKR04.1-W300E-BT49-01-FW) facilitates precise control and monitoring of electrical motors in applications such as printing machines and NC machine tools. It supports a 3 x 400–480 V power input, delivering continuous power across a broad speed range with high precision. The unit integrates a mains contactor, emergency stop shutdown for circuit failures, and a SERCOS interface for high-speed, real-time communication. Dimensions are 1080 mm x 571 mm x 370 mm, with required clearance of 80 mm on top and bottom. It operates within +5°C to +45°C, features air cooling via built-in blower, an external 3 kW bleeder resistor (peak 200 kW), and a 720 kWs auxiliary brake resistor. The drive can be used up to 1000 meters elevation, with digital servo and resolver feedback supported, and is rated for an approximate nominal current of 300 A.
