3.2 Simplified Operation of the VF-nC3
Operation command and Operation frequency command are necessary to operate the inverter.
Operation method and operation frequency setting can be selected from the following.
At default setting, the inverter runs and stops with RUN/STOP key on the panel keypad, and frequency can be set
with the setting dial.
Run / Stop
:
(1) Run and stop using the panel keypad
(2) Run and stop using external signals to terminal
board
Setting the frequency
:
(1) Setting using setting dial
(2) Setting using external signals to terminal board
(0-5V/0-10Vdc, 4-20mAdc)
Use the basic parameters  (command mode selection) 
and (frequency setting mode selection) for selection.
