Operation Setting and Examples of I/O Adjustment
Example for adjusting I/O terminals 1
3.9 Adjust the analog input (Ai1/Ai2)
E.g.) Adjust operation (E.g. for Ai1)
•
Set the ratio to input to limit the operating range of
the frequency command.
(When selecting the frequency through terminal input)

[Cb-03] [Cb-13]
Set the frequency source ratio to the
start ratio of the analog input.
[Cb-04] [Cb-14]
Set the frequency source ratio to the
end ratio of the analog input.
[Cb-05] [Cb-15]
Set the start ratio of the analog input 0
to 10V/0 to 20mA.
[Cb-06] [Cb-16]
Set the end ratio of the analog input 0
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)

[Cb-30] [Cb-32]
Adjust the zero-point reference line for
voltage input 10V/current input 20mA
and the maximum frequency.
[Cb-31] [Cb-33]
Adjust the slope of the reference line
for voltage input 10V/current input
20mA.
*) Use the switch on control circuit terminal board to
change for voltage/current input.

3.10 Adjust the analog output
(Ao1/Ao2/FM)
E.g.) Adjust operation (E.g. for Ao1)
•
Set a value equivalent to 0% output first.
•
Then, adjust a value equivalent to 100% output.
