POINT
 Use the operation panel (
)
to give a start command.
 Use the potentiometer (by connecting terminal 2 and 5) to give a frequentry command.

Set "4" (External/PU combined operation mode 2) in
Pr. 79 Operation mode selection
.
[Connection diagram]
(The inverter supplies 5V of power to the frequency setting potentiometer. (terminal 10))
