A New Circuit for Automatic Identification of Frequency Converter Power Grade
The parameter setting of frequency converter is very important in the debugging process, especially the power grade parameter of the frequency converter is more important. If the power parameter is not set properly, it is possible to cause damage to the equipment. The traditional power parameters are set manually, the probability of error is higher. A new kind of automatic identification circuit for power converter is introduced, which uses 555 timer to generate the square wave with different frequency through the configuration of different resistance and capacitance. Each power level corresponds to a particular square wave frequency, micro control unit (MCU) through the detection of square wave frequency to automatically identify the power of the drive plate.
