PARAMETERS
4.19.4 Setting the frequency by analog input (voltage input)
[Connection diagram]
(The inverter supplies 5V of power to the frequency setting potentiometer.(Terminal 10)
)
POINT
· Use or on the operation panel (FR-DU07) to give a start command.
· Use the potentiometer (by connecting terminal 2 and 5) to give a frequency command.
· Set "4" (External/PU combination operation mode 2) in Pr. 79 Operation mode selection.
Operation example Performing operation at 60Hz.
Operation Display
1. Screen at power-ON
The monitor display appears.
2. Operation mode setting
Set "4" in Pr.79.
[PU] indicator and [EXT] indicator are lit.
(To change the set value, refer to page 62)
3. Start
Press or .
[FWD] or [REV] is flickering as no frequency
command is given.
/
4. Acceleration → constant speed
Turn the potentiometer (frequency setting potentiometer) clock-
wise slowly to full.
The frequency value on the display increases in Pr. 7 Acceleration
time, and " "(60Hz) appears.
5. Deceleration
Turn the potentiometer (frequency setting potentiometer) counter-
clockwise slowly to full. The frequency on the display decreases
in the Pr. 8 Deceleration time, and the motor stops rotating with
" " (0.00Hz) displayed.
[FWD] indicator or [REV] indicator flickers.
6. Stop
Press
[FWD] indicator or [REV] indicator turns OFF.
Change the frequency (60Hz) of the maximum value of potentiometer (at 5V)
Adjust the frequency in Pr. 125 Terminal 2 frequency setting gain frequency. (Refer to page 193.)
Change the frequency (0Hz) of the minimum value of potentiometer (at 0V)
Adjust the frequency in calibration parameter C2 Terminal 2 frequency setting bias frequency. (Refer to
page 193.)
