(X1  X2) x Ymax
b =
(X1 xY2  X2 x Y1)
(X1  X2) x Ymax
In the formulas:
ƕ "b" represents the zero offset.
ƕ "k" represents the gain.
ƕ "X" represents the output frequency.
ƕ "Y" represents the actual output of the AO.
ƕ " Xmax " represents the max. output frequency (determined by F0-10).
ƕ "Ymax" represents the max. output 10 V or 20 mA.
For example, the 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)

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