Know the MCU of frequency-variable controller, the corresponding parameter of compressor, convertible frequency air-conditioner are read from the volatile storage of variable frequency air-conditioner controller
Controller according to reading state modulator compressor operating；
But the setting of toggle switch is by manual operation, if in air-conditioning production and maintenance process, is mistakenly set
Toggle switch, it is corresponding that the MCU of frequency-variable controller will read other compressors from the incorrect region of volatile storage
Parameter causes driven compressor the situation that exception or operational efficiency decline occur, if mistake is used for a long time in frequency-variable controller
The parameter of electric machine and control parameter driving compressor, compressor damage will be led to；
By the model of the compressor based on convertible frequency air-conditioner, the parameter of electric machine and control for obtaining the compressor of convertible frequency air-conditioner are joined
Number, which is automatically performed by frequency-variable controller, without manual intervention, you can realization controls with automatically determining.Specifically, becoming
In the non-volatility memorizer of frequency controller, the model of compressor electric motor is opposite with the parameter of electric machine of compressor and control parameter
Should, after the model for determining compressor electric motor, you can read the complete compressor electric motor parameter stored in corresponding region and control
Parameter processed.
