According to the produce type code, the line for the RD51.1-4B-007-L-NN-NN-NN-FW is 51, the design is 1, the unit type is converter and the nominal connecting voltage is 380 to 480 Volts AC. The AC input to the drive can tolerate 10% of variation around the nominal input rating. The drive specifications for 4 kilohertz pulse frequency include the following: 7.5 kilowatts rated motor output, 0 to 250 Hertz output frequency, 18 Amps rated current, 23 Amps peak current for 60 seconds, 12 kVA rated output and 15 kVA peak power for 60 seconds. The drive specifications for 8 kilohertz pulse frequency include the following: 5.5 kilowatts rated motor output, 0 to 500 Hertz output frequency, 13 Amps rated current, 17 Amps peak current for 60 seconds, 8.6 kVA rated output and 11 kVA peak power for 60 seconds.

The RD51.1-4B-007-L-NN-NN-NN-FW cools through forced air cooling. The air flow requirement for optimal drive cooling is 0.03 cubic meters per second. The recommend ambient temperature range is 0 to 40 degrees Celsius. As the internal drive temperature exceeds the ambient temperature, Bosch has provided the recommended ambient temperature range as a guideline to ensure that the drive is protected from excessively high internal temperatures. The RD51.1-4B-007-L-NN-NN-NN-FW includes a brake chopper which has a continuous power rating of 3.8 kilowatts and peak power rating of 18 kilowatts for 1 second. The minimum resistance value of the brake chopper on the RD51.1-4B-007-L-NN-NN-NN-FW is 35 Ohms. The PC-based RDwin software can be used to parameterize and commission the RD51.1-4B-007-L-NN-NN-NN-FW drive. A type label on the drive contains information relevant to the drive configuration. This product can be shipped globally with a one year warranty period from Wake Industrial.
