Product Description

The RD52.1-7N-004-L-NN-FW is a universal drive controller. It is used for motor control in industrial control applications. The drive is part of the RD52 product range from Bosch Rexroth. The RD52.1-7N-004-L-NN-FW is based on an inverter that is rated for 530 to 670 Volts DC input. The nominal output rating of the drive is 4 kilowatts. The drive inverter does not include a brake chopper. Additional functions are not available on the RD52.1-7N-004-L-NN-FW. However several additional functions are available for RD52 drives and can be specified at the time of ordering. The housing of the drive is designed for forced air cooling. This cooling method relies on blowers or fans for increasing the rate of air flow across the device. The size class of the controller is A. The radio interference suppression level is A1 as per EN 55011.

The RD52.1-7N-004-L-NN-FW drive can be operated at 4 / 8 / 12 kilohertz pulse frequencies. The performance parameters vary with the pulse frequency used during operation. The controller includes an additional 32-bit floating point signal processor for high-dynamic performance applications including servo applications. The RD52.1-7N-004-L-NN-FW can sustain 200% overload for 0.5 seconds and 170% overload for 1 second. Several options are available for operating and parameterizing the RD52.1-7N-004-L-NN-FW controller. These include an optional user panel, RDwin software and RS-232 / RS-485 integrated serial interfaces. Firmware for the RD52.1-7N-004-L-NN-FW drive has to be ordered separately. During installation the signal, line supply and motor power cables should be routed away from each other to eliminate mutual interference. Noise suppression devices are recommended to be installed on relay, solenoid valves and contactors inside the same cabinet as the drive controller. This product can be shipped globally with a one year warranty period from Wake Industrial.
