The Bosch Rexroth R911200407 (RD52.1-7N-055-L-NN-FW) is an inverter-based drive controller designed for induction and synchronous motors. It features a modular structure for flexible integration and operates with a nominal connecting voltage of 530–670 V DC. This unit delivers a rated power output of 55 kW at a 4 kHz pulse frequency and does not include an integrated brake chopper. The power section is located at the rear to support efficient cooling, using forced air flow through fans, blowers, or, for liquid-cooled versions, an external exchanger. The device supports configuration via operator panel or compatible PC software. Storage conditions include a dry, clean environment at −25°C to +70°C, with temperature changes not exceeding 20 K/h, and capacitors should not remain unpowered for more than two years.
