The Bosch Rexroth drive controller MPN R911200158 (RD52.1-4B-055-D-NN-FW) is a three-phase converter with a built-in brake chopper. It operates with a nominal connecting voltage of 3 x AC 380–480 V. At a 4 kHz pulse frequency, the controller supports a rated motor output of 55 kW, an output frequency range of 0–250 Hz, and a rated current of 99 A. When operated at 8 kHz, it delivers 45 kW output over 0–500 Hz. The integrated brake chopper is rated for 33 kW continuous and 130 kW peak operation. The unit employs a plug-through cooler for thermal management and provides RS-232 and RS-485 serial interfaces, with support for optional field bus interfaces including SERCOS, Profibus, Interbus, and CAN bus. The device mass is 49 kg.
