The R911256149 (RAC 2.3-200-460-A0I-Z1) Bosch Rexroth drive controller is designed to operate frameless spindle and asynchronous main spindle motors that have an output of 30kW to 52kW at the drive shaft. As part of the RAC series, it delivers high stiffness and non-stop power across a broad speed range, which is ideal for numerically controlled machine tools. Crucial integrated features include an emergency stop and mains contactor.

With a current rating of 300A, this controller utilizes an enclosed mechanical accessories kit for easy installation. The device is equipped with air slits for heat dissipation during operation.
