Product Description

The Rexroth RD51.1-4N-007-L-NN-FW is a drive control device. A drive control device controls the speed of an AC motor by varying the frequency supplied to the motor. They are used to regulate the output voltage in proportion to the output frequency to provide a relatively constant ratio of voltage to frequency (V/Hz), as required by the features of the AC motor to produce suitable torque. Typical applications for the RD51.1-4N-007-L-NN-FW include chemical and process technology, machine tools, packaging and assembly systems. Safety instructions provided by the manufacturer should be followed to avoid risk of bodily damage and damage to components. Before the electrical system is commissioned for the first time, a professional electrician must check whether the device’s electrical and mechanical systems. The line supply and control voltages can be powered-up after all of the control, setpoint and line supply feeder cables have been connected.

The rated power output for the RD51.1-4N-007-L-NN-FW is 7.5 kilowatts. The drive control device uses the Converter 3 x AC 380 to 480volts with a +/- 10% variance limit. The drive control device supports a U/f curve control line. It is supplied without a built-in brake chopper for the converter. It has a forced air-cooling mode with =< 110 kilowatts. In order to reduce the harmonics fed back into the line supply, radio interference suppression filters and line reactor are integrated into the AC drive converters. The drive control device is in full compliance with the EMC Directives regarding noise immunity and noise emission according to the EMC Product Standard for electric drives EN 61800-3, EN 55011 Class A (IEC 61800-3 and is immune to noise in conformance with EN 50082-2. This product can be shipped globally with a one year warranty period from Wake Industrial.
