(2) -10V ~ ratio of +10V is as following.
(3) Setting O2 starts selection I038 by 0(singleness) O2, to use L signal individually, and AT
function does not allocate. (Please take care Intelligent input terminal function I002's initial
value was set by 16 (AT).)
(4) Or, I038 if input AT signal after set I049 by 1(O/O2) by 0/O2, L Simple cycle operation is
available.
(5) The frequency order method can be selectable according to O2 starts selection I038's setting
and AT terminal selection I049's association.
(6) For the detailed contents refer to 9.2.13 chapter(analog input voltage, electric current
switching).
(7) When an initial value 0 ~ the maximum frequency (F003) does not agree with the input
External electric current signal -10~10V, change correctly I032 and I033.

ex)
When you input -5V ~ +5V to O2-L terminal,
please set I036 = -50%, I037= 50%.
