3.4.4 Setting the frequency by analog input (voltage input)
POINT
Operation panel ( ) is used to give a start command.
Frequency command is given from the potentiometer (by connecting terminal 2 and 5.)
Pr. 79 Operation mode selection must be set to "4" (External/PU combined operation mode 2).
[Connection diagram]
(The inverter supplies 5V of power to the frequency setting potentiometer. (terminal 10))
Operation
example
Operate at 60Hz.
Operation Display
1.
Screen at powering ON
The monitor display appears.
2. Change the Pr. 79 setting to "4".
(Refer to page 34 for change of the setting.)
[PU] display and [EXT] display are lit.
3. Start
Turn ON .
[RUN] flickers fast as no frequency command is
given.
4. Acceleration constant speed
Turn the potentiometer clockwise slowly to full.
The frequency value on the indication
increases according to Pr. 7 Acceleration time
until " " (60.00Hz) is displayed.
[RUN] display is lit during forward rotation
operation and flickers slowly during reverse
rotation operation.
5. Deceleration
Turn the potentiometer counterclockwise slowly
to full.
The frequency value on the indication
decreases according to Pr. 8 Deceleration time
and displays " " (0.00Hz) when the motor
is stopped.
[RUN] flickers fast.
6. Stop
Switch power OFF .
[RUN] turns OFF.
