The R911253333 (RAC 2.2-250-380-AY0-W1) is an AC main spindle drive controller from the Rexroth RAC 2 series, designed for precise spindle motor management via internal position control loops and capable of c-axis operation. It features a rated connection voltage of 3 x AC 400 V at 50-60Hz, a rated current capacity of 250 A, and utilizes an internal blower for cooling. The controller provides additional encoder and synchronous inputs, supports incremental encoder (JL) feedback, and analog speed command input (+/- 10 V). Direct current braking is integrated for spindle stoppage during power loss. Configuration is facilitated by an AS programming module, and terminal X4 (9 poles) serves as the interface. The device is specified for operation within a 5 to 45 °C temperature range.
