2-1-2 Accepting Operation Commands While Changing
Parameters
With the default settings, the Inverter will not accept operation commands when param-
eter settings are being changed. This functions as a safety measure to prevent the motor
from rotating if the operation command is mistakenly set to ON when changing parame-
ters.
Depending on the operating conditions, however, the user may want to have operation
commands accepted even while parameters are being changed. In that case, change
the following settings.
H Using the Indicators to Determine When Operation Commands Can Be
Accepted
The indicators on the Digital Operator can be used to determine if operation commands will be accepted
or not while changing parameters.
Green: Operation commands will be accepted if the indicator lights green.
Red: Operation commands will not be accepted after the Inverter stops if an indicator lights red.
Therefore, if the indicator lights red when changing parameters or when switching between local and
remote operation, operation will continue, but once the Inverter stops, the Inverter will not operate even
if the operation command is set to ON again.
The FREF indicator will light when the power supply is turned ON.
Indicator Color
FREF Green
FOUT Green
IOUT Green
MNTR Green
F/R Green
LO/RE Red
PRGM Red
Note Perform the settings given in the following description to have operation commands accepted
while the red indicator is lit (i.e., while changing parameters or switching between local and re-
mote.)
Set n001 (Parameter write–prohibit selection/parameter initialization) to 5.
S The default value for n001 is 1.
S Operation commands will not be accepted when n001 itself is being changed.
S Some parameters cannot be changed during operation. Those parameters cannot be changed
during operation even if the setting for n001 is changed.
S When n001 is changed to 5, an operation command will be accepted even when changing pa-
rameters, such as during trial operation. Thoroughly check safety before changing any setting.
