Screen at powering on
The monitor display appears.
2.
Change the Pr. 79 setting to "
(Refer to page 43 for change of the setting.)
3.
Start
Press the start switch
Operation status indication of FWD (or REV)
flickers.
CAUTION
When both the forward switch and reverse
switch turn on, the inverter will not start.
Also, if both switch turn on while running,
the inverter stops.
4.
Acceleration → constant speed
Turn the volume (frequency setting
potentiometer) clockwise slowly to full.
The frequency value on the indication increases
according to Pr. 7 Acceleration time until 60Hz is
displayed.
5.
Deceleration
Turn the volume (frequency setting potentiometer)
counterclockwise slowly to full.
The frequency value on the indication decreases
according to Pr. 8 Deceleration time unitl 0.00Hz is
displayed and operation status indication of FWD
or REV flickers.
The motor stops.
6.
Stop
Press .
Operation status indication of FWD (or REV)
turns off.
Change the frequency (60Hz) of the maximum value of potentiometer (at 5V, initial value)
Adjust the frequency in Pr. 125 Terminal 2 frequency setting gain frequency. (Refer to page 82.)
Change the frequency (0Hz) of the minimum value of potentiometer (at 0V, initial value)
Adjust the frequency in calibration parameter C2 Terminal 2 frequency setting bias frequency. (Refer to
Instruction Manual (applied).)
