The R911201009 (RD51.2-4B-003-L-A1-FW) RD51 drive controller is a Bosch Rexroth product engineered for motor control operations. With a built-in brake chopper, this three-phase drive converter is rated for an input voltage between 380 to 480 Volts AC. It signifies an output power of 3 kW at a 4 kHz pulse frequency. At this frequency, it offers an output frequency of 0 to 250 Hz, a 7.5 Amps rated current, and a peak current of 13 Amps for 1 second, with a 4.9 kVA rated output. At 8 kHz pulse frequency, the output power decreases to 2.2 kW, with other parameters adjusted accordingly. It also entails brake chopper power of 1.5 kW continuous and peak at 10 kW for 1 second, at both 4 and 8 kHz. For optimal performance, the forced air cooling housing requires a minimal airflow rate of 0.03 m3/s. It further includes additional features like filter current feedback, starting lockout and stand-by power operations. External 24 Volts supply DC is needed for the stand-by power feature.
