The Bosch Rexroth R911234780 (RAC 2.2-200-380-A00-Z1) is an AC main spindle drive controller engineered for precise servo control in machine tool applications. Compatible with 1MB frameless and 2AD asynchronous motors, it supports exact C-axis operations via an advanced feedback system with a resolution of 1/400,000 revolutions, ensuring continuous monitoring and adjustment of the rotor position for low-speed accuracy. The controller accommodates asynchronous and incremental encoder inputs for spindle synchronization and CNC positioning tasks. It integrates with Sercos, PLC, and traditional CNC controllers, and supports serial interface connections for parameter configuration. Key specifications include a rated connection voltage of 3 x AC 400 V (50-60 Hz), rated current of 200 A, internal blower cooling, analogue speed command input (+/- 10 V), and a 9-pole X4 interface terminal. The unit features an additional bleeder and is provided without an additional encoder input.
