Operation
1.
Screen at powering on
The monitor display appears.
2.
Change the Pr. 79 setting to "
(Refer to page 52 for change of the setting.)
3.
Start
Check that the terminal 4 input selection signal (AU) is on.
Press the start switch
FWD or REV of operating status indication 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
Perform 20mA input.
The frequency value on the indication increases
according to Pr. 7 Acceleration time until
(60.00Hz) is displayed.
5.
Deceleration
Perform 4mA input.
The frequency value on the indication decreases
according to Pr. 8 Deceleration time until
displayed and the operating status indication of FWD or
REV flickers.
The motor stops.
6.
Stop
Press .
FWD or REV of the operating status indication turns off.
REMARKS
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to chapter 4 of
(applied).)
Change the frequency (60Hz) at the maximum value of potentiometer (at 20mA, initial value)
Adjust the frequency in Pr. 126 Terminal 4 frequency setting gain frequency. (Refer to page 94.)
Change the frequency (0Hz) at the minimum value of potentiometer (at 4mA, initial value)
Adjust the frequency in calibration parameter C5 Terminal 4 frequency setting bias frequency. (Refer to
