Setting the frequency by analog input (voltage input)
on the operation panel (FR-DU07) to give a start command.
· Use the potentiometer to give a frequency command. (by connecting terminal 2 and 5 (voltage input))
· Set "4" (External/PU combination operation mode 2) in Pr. 79 Operation mode selection.
(The inverter supplies 5V of power to the frequency setting potentiometer.(Terminal 10))
