(3) Setting value alarm display
When a setting value and one of the following alarms are alternately displayed on the LED, a setting
value limitation is indicated.
1-1 I
alarm (upper limit alarm)··· When the upper limit of the setting range has been reached, or when
the setting value of the current parameter being changed exceeds
its upper limit value as a result of another parameter setting value
being changed. (In the latter case, the value will be corrected to its
upper limit value.)
L O
alarm (lower limit alarm)··· When the lower limit of the setting range has been reached, or when
the setting value of the current parameter being changed exceeds
its lower limit value as a result of another parameter setting value
being changed. (In the latter case, the value will be corrected to its
lower limit value.)
The data setting of parameters that have an adjustment range limited by the setting values of
IL L
I
and
IU
L
I ,
such as the preset speed frequency parameters, cannot exceed the values of
IL
L
I
and
[IO.
When the
IF
1-11 ,
IU
L
I
or
IL
L
I
parameter values are changed, the setting values of some parameter
may exceed their limits as a result. In this case, an alarm will be displayed when a parameter with a
setting exceeding its adjustment range is selected and adjustent is attempted. To change a parameter
with this type of setting value, the moment that the
@ (Y)
keys are pressed, the alarm will be
displayed and the setting value will change to its limiting value.
If
IU
L
I
is exceeded, the value will become the same value as
IU
L

If
ILL

is exceeded, the value will become the same value as
ILL
