【Example】：
Pr.128：Motor Maximun speed limit = 1000
Pr.297：PID-switch point = 80.20
Î
XX =(800/1000)×100％ = 80％；YY =(200/1000)×100％ = 20%
Pr.255：PID P- gain1 = 500
Pr.256：PID I - gain1 = 50
Pr.295：PID P-gain2 = 100
Pr.296：PID I - gain2 = 10
※ When actually speed > 800rpm，main gain = PID- Gain1
※ When actually speed < 200rpm，main gain = PID-Gain2
※ When actually speed between 200rpm ~ 800rpm，main gain = linear adjustment。
