3.2Simplified 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 ST

 

terminal and the F terminal). Also, the frequency is set according to the potentiometer/voltage/current signals to

3

analog input terminals (such as the RR/S4 terminal, VI/II terminal and RX terminal).

￿For more details, refer to Section 7.
