start ratio of the analog input.
Set the frequency source ratio to the
[Cb-04] [Cb-14]
end ratio of the analog input.
Set the start ratio of the analog input 0
[Cb-05] [Cb-15]
to 10V/0 to 20mA.
Set the end ratio of the analog input 0
[Cb-06] [Cb-16]
to 10V/0 to 20mA.

Ai2 adjustment can be done in similar way to Ai1 by
using Ai2 parameters in order to Ai1.
E.g.) Make a fine adjustment (E.g. for Ai1)

Adjust the zero-point reference line for
[Cb-30] [Cb-32] voltage input 10V/current input 20mA
and the maximum frequency.
Adjust the slope of the reference line
[Cb-31] [Cb-33] for voltage input 10V/current input
20mA.
*) Use the switch on control circuit terminal board to
change for voltage/current input.
Operation Setting and Examples of I/O Adjustment
While setting [Cb-07] = 00,
the frequency command
from 0% to [Cb-05] will be
set by [Cb-03].
