3.2 Simplified operation of the VF-AS1
On of three operation modes can be selected: terminal board operation, operation panel and combination of both.
⇒ For other operation modes, refer to Section 5.5.
Terminal board mode
:Operation by means of external signals
Operation panel mode :Operation by pressing keys on the operation panel
Operation panel + terminal board mode :Frequency, start/stop signals can be
sent individually from the operating panel and terminal board.
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 S3
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.
