The Bosch Rexroth R911200731 (RD51.1-4N-005-L-DF-FW) is an industrial drive converter designed for three-phase 5 kW motors, supporting AC 380 to 480 V (±10%) input. The unit features a speed control ratio of 1:20, frequency precision of 0.01%, and 2% speed accuracy. Construction details include aluminum-Elko DC link capacitors, line filters, and insulated cables for noise reduction. The converter contains a PROFIBUS-DP interface, supports external 24 V standby power, and uses U/f curve control. It is rated for operation in 0-40°C ambient temperature and 85-90% humidity, with an IP20 protection class. Forced air cooling is implemented for units ≥110 kW, though this unit has 5 kW rated output. A spacing of 100 mm above and below the unit is recommended. Factory-assigned firmware is included; no built-in brake chopper is present.
