The Bosch R911200927 (RD51.1-5N-315-F-FV-FW) is a RD51 three-phase drive system intended for 500 Volts AC input. This converter-based system does not feature a brake chopper but it does possess forced air cooling and integrated liquid circulation. Its rated output stands at 315 kilowatts, with firmware for the system needing to be procured separately. The output frequency range is 0-150 Hertz at 4 kilohertz pulse and 0-250 Hertz at 8 kilohertz pulse. The R911200927 (RD51.1-5N-315-F-FV-FW) meets 3K3 environmental class standards and requires a minimum cooling air flow of 0.8m³/s. With protection category IP20 for the drive system housing, it weighs 358 kg. Optional components include a control panel, PC-based software and communications cards with integrated RS-232/RS-485 serial interfaces included on the logic and control board. This global product from Indramat USA has a one year warranty.
