This function code can be used to adjust the analog outputs defined in the above table. The adjusted
analog value is the actual output of AO terminal.
P7.09 is used to determine the positive and negative polarities of the gain or bias.
Since function codes P7.05 ~ P7.09 are different from other function codes, adjustment will affect the AO
output timely, that is, by debugging the parameters P7.05-P7.09, you will get the analog output of A01
and A02.
Both AO1 and AO2 have the same calibration way. Take AO1 as an example:
Set P7.05 to 100.0% and P7.06 to 20.0%,namely, K=1 and b=2V, and the AO1 characteristics curve is as
shown in Figure 6−24 and Figure 6−25.

Set P7.05 to 100.0% and P7.06 to 120.0%, namely, K=1 and b=12V, and the AO1 characteristics curve is
as shown in Figure 6−26.
Set P7.05 to 100.0% and P7.06 to 80.0%, namely, K=1 and b=8V, and the AO1 characteristics curve is
as shown in Figure 6−27.
