3.2.1 Terminal board operation

In this mode, the motor is started or stopped according to the ON/OFF signal to input terminals (such as the ST
terminal and the F terminal). Also, the frequency is set according to the potentiometer/voltage/current signals to analog
input terminals (such as the PP terminal, RR/S4 terminal and VI/II terminal).
