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 RR/S4 terminal, VI/II terminal and RX terminal).
For more details, refer to Section 7.
