Product Description

The Bosch Rexroth RD52.1-7N-110-L-NN-FW is a universal drive controller. It is deployed for motor control in industrial and commercial applications. The RD52 series of controllers is widely deployed for applications that include chemical technology, process technology, machine tools, packing machines and foodstuff machines. Bosch only allows use and operation of the controller under specified mounting and installation conditions and under recommended ambient conditions. Use of the controller for applications other than those specified and described in the product documentation is considered improper and must be avoided. The RD52.1-7N-110-L-NN-FW controller is based on an inverter. This inverter operates at DC voltages ranging from 530 to 670 Volts DC. The drive inverter does not feature a built-in brake chopper. At 4 kilohertz pulse, the RD52.1-7N-110-L-NN-FW can be used with motors rated for 110 kilowatts.

At 6 kilohertz pulse, the RD52.1-7N-110-L-NN-FW can be used with motors rated for 90 kilowatts. The controller is available in an IP20 rated enclosure that does not provide moisture ingress protection. The recommended ambient conditions for operation include 0 to 40 degrees Celsius temperature and 0 to 1000 meters altitude. Proper heat dissipation requires the use of fans or blowers to force air across the heated controller body. The minimum air flow required for cooling is 0.4 m³/s. Size class of the RD52.1-7N-110-L-NN-FW is E and its weight is 44 kilograms. Bosch installs radio interference filters on the RD52 drives to suppress harmonics fed back into the main supply. Commissioning of the RD52.1-7N-110-L-NN-FW is performed from an operator panel or a PC with Rdwin software. The RD52.1-7N-110-L-NN-FW performs optimally when it is properly installed. Therefore trained personnel should handle and install the drive system. This product can be shipped globally with a one year warranty period from Wake Industrial.
