Remote and local modes

The inverter is available in either remote or local mode.
In remote mode, run and frequency commands are selected by function codes. In local mode, the
command source is the keypad, regardless of the settings specified by function codes.
Holding down the
modes.
Switching these modes is also possible by a digital input signal provided from the outside of the
inverter. You need to assign LOC (Select local (keypad) operation) as a digital input signal to any of
terminals [X1] to [X7].
( Refer to E01 through E07.)
The current mode can be checked by the status icons. The
in remote mode and the
Switching from remote to local mode automatically inherits the frequency settings used in remote
mode. If the motor is running at the time of the switching from remote to local, the run command
will be automatically turned ON so that all the necessary data settings will be carried over. If,
however, there is a discrepancy between the settings used in remote mode and ones made on the
keypad (e.g., switching from the reverse rotation in remote mode to the forward rotation only in
local mode), the inverter automatically stops.
