5.1.1
Setting the frequency by the operation panel
The inverter needs frequency command and start command.
Frequency command (set frequency) determines the rotation speed of the motor.
Turning ON the start command starts the motor to rotate.
Frequency command (set frequency) determines the rotation speed of the motor.
Turning ON the start command starts the motor to rotate.

Operation at the frequency set in the frequency setting mode of the operation panel
refer to 5.1.1 (Refer to page 23)
Operation using the setting dial as the potentiometer
refer to Chapter 4 of the Instruction Manual (Applied)
Change of frequency with ON/OFF switches connected to terminals
refer to 5.1.2 (Refer to page 24)
Perform frequency setting using voltage input signal

refer to Chapter 4 of the Instruction Manual (Applied)
Operation example
Operate at 30Hz.
Operation
1.
Screen at power-ON
The monitor display appears.
2.
Operation mode change
Press
to choose the PU operation mode. PU indicator is lit.
3.
Frequency setting
Turn
to show the frequency "
" (30.00Hz) you want to set. The frequency flickers for about 5s. While the value is
flickering, press
to set the frequency. " " and "
" flicker alternately. After about 3s of flickering, the display of the
value goes back to "
" (0.00Hz) (monitor display). (If
is not pressed, the display of the value goes back to "
"
(0.00Hz) after about 5s of flickering. In that case, turn
again, and set the frequency.)
4.
Start acceleration constant speed
Press
to start operation.
The frequency value on the display increases in Pr. 7 Acceleration time, and "
" (30.00Hz) appears.
(To change the set frequency, perform the operation in above step 3. The previously set frequency is displayed at first.)
5.
Deceleration stop
Press
to stop. The frequency value on the display decreases in Pr. 8 Deceleration time, and the motor stops running with
"
" (0.00Hz) displayed.
REMARKS
can also be used like a potentiometer to perform operation. (
Refer to Chapter 4 of the Instruction Manual (Applied).)
When you always operate in the PU operation mode at power-ON, set Pr.79 Operation mode selection = "1" to choose the PU
operation mode always.
