The Bosch Rexroth RAC 2.2-250-380-L00-Z1 drive controller possesses remarkable features that enhance its application as a primary spindle drive for numerically-operated machines. This device features a broad speed range, ensuring high stiffness performance alongside an expansive 400A current type. It operates on a connection voltage of 3x AC 400V/50-60Hz. Its internal position control loop enables the spindle to position itself responsively to signals, with feedback from the motor. This drive controller is directly connected to a three-phase supply network using 3x AC 400V, 50Hz, and it integrates an emergency stop switch guaranteeing safety in the event of brake failure. A built-in fan mitigates overheating concerns, cooling the control cabinet's interior or exterior. It also incorporates a SERCOS interface for quick, efficient operations while providing effective relay of speed, torque, and position values. Although it doesn't feature an additional interface and encoder input, this product backs consumers with a one-year warranty.
