[Connection Ex.: voltage input]
(The inverter supplies 5V power to the frequency
setting potentiometer. (Terminal 10))
[Connection Ex.: current input]
(Assign one parameter between Pr. 178 - 184 to the
AU signal.)
● The operation panel ( ) is used to issue start commands.
● Frequency commands are issued using the potentiometer (frequency setting potentiometer, voltage input)
or current inputs of 4-20mA.
● Set Pr. 79 Operation mode selection to "4" (External/PU operation mode 2).
