The Bosch Rexroth drive control MPN R911201104 (RD51.1-4N-022-L-NN-FW/S111) delivers a rated power output of 22 kW and supports an output frequency range of 0 Hz to 250 Hz. It operates with a nominal connecting voltage of 3 x AC 380-480 V and utilizes forced air cooling. Installation requires a vertical mounting position with a 100 mm clearance above and below the unit in the control cabinet for adequate cooling. The device measures 560 x 180 mm and is secured using M6 screws. For safe operation, cables must be routed at least 20 cm apart. The enclosure environment must remain moisture-free with relative humidity below 90% and dust filtration is necessary. The unit is not compatible with plastic motor terminal boxes. After shutdown, the device's DC link capacitors may retain high voltage for up to five minutes. This drive control is a converter type, without a built-in brake chopper, and features a mechanical grid pattern of 22.5 mm.
