4.1.1 How to set basic parameters [Basic parameter]
Every basic parameters can be set in the same way.
Follow the procedure below to set a basic parameter.
(Example of setting: Changing the maximum frequency from 80 to 60 Hz)
Key operated LED display Operation

The operation frequency is displayed. (Out of operation.)
(If the monitor display mode setting parameter
 is
set at [Operation frequency])

Press the [MON] key to call up the first basic parameter
 (automatic acceleration/deceleration).

Select "" by pressing the or key.

Press the Enter key to display the changed maximum
frequency.

Change the maximum frequency to 60 Hz by pressing
key.
 
Press the Enter key to save the change. Then,  and the
set maximum frequency are displayed alternately.
After this,
About the parameter's adjustment range
: A value larger than the upper-limit value is entered or the value set for the currently-selected
parameter becomes larger than the upper-limit value because another parameter was changed.
: A value smaller than the lower-limit value is entered or the value set for the currently-selected
parameter becomes smaller than the lower-limit value because another parameter was changed.
If the above alarm code  or  blinks, change the parameter setting below the  value or
above the  value, respectively. When any of these alarm codes is blinking, no change can be
made to any parameter.
