When "1" (storing roll diameters enabled) is set,
the input of the Stored winding diameter clear
(X109) signal is required.
The storing of roll diameters (writing in EEPROM)
is conducted when the inverter power or the X114
signal turns OFF. Note that the storing is not
conducted when the RES signal is input.
Therefore, avoid inputting the RES signal
frequently without storing the roll diameters.
For the input of the RES signal by necessity such
as a reset of the inverter fault, it is recommended
to configure the sequence that the RES signal will
be input after the X114 signal turns OFF and
before the X114 signal turns ON again.

this parameter is not set).
