Run/stop : ON/OFF of terminals F-CC/R-CC
(Standby: connection of terminals
S3 and CC)
Speed command : Set the frequency, using
the
the operation panel.
The inverter is factory-
configured so that, if F and
R are turned on at the
same time, the inverter will
stop operation. If
necessary, the direction of
rotation can be reversed
by changing parameter
settings.
⇒ Refer to Section 6.2.1.
To save the frequency,
press the ENTER key.
Then,  and the set
frequency are
displayed alternately
for a while.
Run/stop : Press the RUN and
the operation panel
To switch between forward run and reverse run,
use the forward/reverse run selection .
