The Bosch Rexroth MPN R911258356 (RAC 3.5-100-460-L00-Z1-220) is an AC main spindle drive controller designed for numerically-controlled machine applications requiring precise spindle motion. It supports a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15%, or 3 x AC 460 V, with a rated current of 100 A and includes an additional bleeder for enhanced energy management. The device is cooled by an internal blower and features integrated motor feedback and an internal position control loop for responsive positioning. It employs a SERCOS interface via optical waveguides (terminal X4) for transmitting speed, torque, and position data. The speed set-point is provided as a 10V signal. The controller does not include an additional encoder input. Electronics operate at AC 230 V, 50-60 Hz.
