9.转速侦测 RPM detection |
I Cycle
Timer（X） 转动 Running TI T3 VOH
T2 T4 VOL
T=T1+T2+T3+T4 |
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
