9-2．转速侦测说明

9-2-1．输出波形：方波

        Output waveform: square wave.

9-2-2．当电压值愈高（Voltage Y值），则输出波形愈高

       When the voltage value is higher (Voltage Y)then output waveform is higher

9-2-3．当风扇不转，则输出波形为一水平线。

      When the fan is shutdown then output waveform is a horizontal line

9-2-4．循环距离越长（Voltage Y值），则转速越慢

      The cyclic distance is longer then the RPM is slower.

9-2-5．转速计算公式如下：

       RPM formula as follows:

                           RPM=    60000

                                    X（ns）

             <例>Example

                X=15

                 Ls=1000ns

                 Lmin=60000ns

                         RPM =    60000    =4000
