In the formulas:
Ɣ
"b" represents zero offset.
Ɣ
"k" represents gain.
Ɣ
"X" represents output frequency.
Ɣ
"Y" represents actual output of the AO.
Ɣ
" Xmax " represents max. output frequency (determined by F0-10).
Ɣ
"Ymax" represents max. output 10 V or 20 mA.
For example, AO is used for output of frequency reference. To implement output of 8 V (Y1) at 0
Hz (x1) and output of 4 V (Y2) at 40 Hz (X2) according to the formulas, you can obtain gain and

Then you can set F5-11 to -0.5 and set F5-10 to 80%.
AO output signal type and corresponding max. value are as follows:
