Product Description

The Bosch Rexroth RD52.1-7N-132-F-M1-FW is a 132 kilowatts rated drive controller. Overload capability of the controller is 170% for 1 second. The controller is based on an inverter. The drive does not include a brake chopper. Input voltage range of the controller is 530 to 670 Volts DC. Power section of the controller is designed for cooling at the rear. This allows use of forced air cooling. The RD52.1-7N-132-F-M1-FW is designed for forced air cooling with integrated liquid circulation i.e. the drive has an integrated heat exchanger. Controller specifications for 4 kilohertz pulse frequency are: 132 kilowatts rated motor output, 0 to 250 Hertz output frequency, 230 Amps rated current output, and 151 kVA rated output. Controller specifications for 8 kilohertz pulse frequency are: 110 kilowatts rated motor output, 0 to 500 Hertz output frequency, 195 Amps rated current output, and 128 kVA rated output.

Weight of the drive unit is 128 kilograms. Its size class is G. The protection class of the RD52.1-7N-132-F-M1-FW is IP20. As the controller is not dust-proof or water-proof, operators can mount it inside a cabinet for improved protection. Power loss of the RD52.1-7N-132-F-M1-FW is 5.2 kilowatts and the cooling air requirement is 0.4 m³/s. RD52 drives support multiple hardware options. The hardware option supported by the RD52.1-7N-132-F-M1-FW is a frequency converter with output chokes. Options for operator control and visualization include a user panel and RDwin PC-based software. Serial interfaces - such as RS-232 and R-485 - are available on the logic and control board. These interfaces can also be used for controller programming. Installation errors can adversely affect controller performance. Therefore only qualified personnel should install and operate the controller.
