The R911265947 (RAC 2.3-200-460-L00-Z1) is a Bosch Rexroth AC main spindle drive controller engineered for regulating asynchronous and frameless spindle motors in numerically controlled machine tools. It features an internal position control loop for accurate spindle positioning via motor feedback, capable of resolving movements down to 1/4,000,000th of a revolution. Key specifications include operation with a 3 x AC 400 V, 50 Hz ±15% or 3 x AC 460 V supply, rated current of 200 A, and support for SERCOS interface-based speed regulation without additional encoder input. The device incorporates integrated safety elements, an additional bleeder, internal blower cooling, and a built-in heat sink.
