The R911200687 (RD51.1-4B-037-L-D1-FW) is a universal drive controller from Bosch Rexroth’s REFUDrive RD50 series. The firmware, which needs to be purchased separately, supports various features. It operates on 380 to 480 Volts AC and yields a nominal output of 37 kilowatts at a 4kHz pulse frequency. While it can also work on 200 to 230 Volts AC, this will result in output derating. At 8kHz pulse frequency, the controller generates 30 kilowatts of power. Its additional features include 24 Volts standby power and the ability to connect an RZC01.1-XT with a NAMUR terminal strip to enhance the drive functionality. It requires forced ventilation, and operates efficiently between 0-40 degrees Celsius and at up to 90% non-condensing relative humidity. The drive, weighing 36kg, comes with a one-year warranty and can be shipped worldwide. It should be installed and operated by trained technical personnel.
