3.5.5

Perform frequency setting by analog (current input)

POINT
· Switch terminal STF(STR)-SD on to give a start command.
· Turn the AU signal on.
· Set "2" (external operation mode) in Pr. 79 Operation mode selection

1.
Power on → operation mode check
For the initial setting, the inverter operates in
the external operation mode [EXT] when
powering on. Check that the operation
command indication is [EXT]. If not displayed,
press to change to the external [EXT]
operation mode. If the operation mode still does
not change, set Pr. 79 to change to the external
operation mode.
2.
Start
Turn the start switch (STF or STR) on.
FWD or REV of operation indication flickers.
CAUTION
When both the forward switch and reverse
switch are on, the inverter will not start.
Also, if both switches turn on while running,
the inverter decelerates to stop.
3.
Acceleration → constant speed
Perform 20mA input.
The frequency value on the indication
increases according to Pr. 7
Acceleration time until 60.00Hz is displayed.
4.
Deceleration
Perform 4mA input.
The frequency value on the indication
decreases according to Pr. 8
Deceleration time until 0.00Hz is displayed
and FWD or REV of the operation status
indication flickers.
The motor stops.
5.
Stop
Turn the start switch (STF or STR) off.
REMARKS
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to section 4 of
(applied).)
