2) Setting the run and stop frequencies (forward run, reverse run and
coast stop) by means of external signals and setting the operation
frequency with the operation panel
Title Function
Example of setting
Run/stop : ON/OFF of terminals F-CC/R-CC
(Standby: connection of terminals
ST and CC)
Speed command : Set the frequency, using
the keys on
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.
