The R911256199 (RAC 2.2-250-380-L00-Z1) is a Bosch Rexroth AC main spindle drive controller engineered for numerically operated machinery. It operates with a rated connection voltage of 3 x AC 400 V at 50–60 Hz and supports a rated current of 250 A, accommodating applications requiring robust current supply. The unit incorporates an additional bleeder for enhanced braking performance and is cooled by an internal blower. Its precision operation is enabled by an internal position control loop and direct current braking. Interface connectivity includes an X4 terminal with optical waveguides and a speed command through the SERCOS interface. This controller does not include an additional encoder input and provides a 10V speed set-point.
