PU operation mode
Screen at powering on
The monitor display appears.
Change the Pr. 79 setting to "4".
(Refer to section 4.3.7 for change of the setting.)
Check that the terminal 4 input selection signal
(AU) is on.
Press the start key FWD or REV. Operation
status indication FWD or REV flickers.
CAUTION:
When both the forward and reverse key are
pushed, the inverter will not start. Also, if both
keys are pushed while running, the inverter
stops.
Acceleration → constant speed
Perform 20mA input. The frequency value on the
indication increases according to Pr. 7
"Acceleration time" until 50Hz is displayed.
Deceleration
Perform 4mA input. The frequency value on the
indication decreases according to Pr. 8
"Deceleration time" until 0.00Hz is displayed
and operation status indication of FWD or REV
flickers.
The motor stops.
Press the STOP/RESET switch.
Operation status indication of FWD (or REV)
turns off.

NOTES
Pr. 184 "AU terminal function selection" must be set to "4" (AU signal) (initial value). (Refer
to section 6.14.1.)
Change the frequency (50Hz) at the maximum value of potentiometer (at 20mA) by adjusting
the frequency in Pr. 126 "Terminal 4 frequency setting gain frequency". (Refer to
section 5.3.6.)
Change the frequency (0Hz) at the minimum value of potentiometer (at 4mA) by adjusting
the frequency in calibration parameter C5 "Terminal 4 frequency setting bias frequency".
(Refer to section 6.20.5.)
