Product Description

The Bosch Rexroth RD52.1-7N-110-L-V1-FW/S129 is an inverter-based drive system. It is designed for control of Bosch induction and synchronous motors. The inverter is without a brake chopper. The supply rating of the inverter is 530 to 670 Volts DC. The supported pulse frequencies are 4 kilohertz, 6 kilohertz and 12 kilohertz. Performance specifications for the drive vary with the choice of pulse frequency. The rated motor output is 90 kilowatts for all pulse frequencies. The rated current is 195 Amps for 4 kilohertz, 165 Amps for 6 kilohertz and 80 Amps for 12 kilohertz. The output apparent power is 128 kVA for 4 kilohertz, 109 kVA for 6 kilohertz and 53 kVA for 12 kilohertz. Cooling method for which the drive is designed is forced air cooling. The minimum required air flow that will ensure ambient temperature within recommended limits is 0.4 cubic meters per second.

The ambient temperature for drive operation is 0 to 40 degrees Celsius. The environmental class of the drive is 3K3 as per DIN IEC 721-3-. The radio interference suppression rating of the RD52.1-7N-110-L-V1-FW/S129 is A1 as per EN 61800-3 / EN 55011. The housing of the RD52.1-7N-110-L-V1-FW/S129 has an environmental protection rating of IP20. For improved protection from dust and liquids, the drive has to be mounted inside a control cabinet. Standby power function on the RD52.1-7N-110-L-V1-FW/S129 enables control electronics operation without line supply. This drive features requires an external 24 Volts DC power supply. With this features, data sets can be parameterized, read and written into even when the drive is not connected to the line supply voltage. The weight of the RD52.1-7N-110-L-V1-FW/S129 universal drive is 44 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
