The Bosch Rexroth R911234780 (RAC 2.2-200-380-A00-Z1) is a high-quality drive controller designed for superior servo applications and is compatible with 1MB frameless motors and 2AD asynchronous motors. This state-of-the-art device enables precise C-axis operations, courtesy of an advanced feedback system boasting a resolution of 1/400 000 revolutions. This facilitates meticulous motion control even at minimal speeds by continually monitoring and adjusting the rotor’s position. Spindle synchronization is achieved through asynchronous input and additional encoder input. It also features an incremental encoder input for controlled CNC positioning during tapping and screwing operations. For enhanced parameter management, it accommodates a serial interface connection with a PC, while also supporting connection to digital set-points via an optional interface. Suitable for integration with Sercos interface, PLC controllers, or classic CNC controllers, this device ensures robust control response and precision. It is ideal as a main spindle drive in machine tools due to its wide operational speed range. The unit comes with a one-year global warranty from Indramat USA.
