b3.43 AO1 zero offset
coefcient
These two parameters are used to correct the zero
offset of analog output and the output amplitude
deviation. They can also be used to dene the
desired AO curve.
If "b" represents zero offset, "k" represents gain,
"Y" represents actual output, and "X" represents
standard output, the actual output is: Y = kX + b.
The zero offset coefcient 100% of AO1 and AO2
corresponds to 10 V (or 20 mA). The standard
output refers to the value corresponding to the
analog output of 0 to 10 V (or 0 to 20 mA) with no
zero offset or gain adjustment.
For example, if the analog output is used as the
frequency reference, it is expected that the output
is 8 V when the frequency is 0 V, and the output is
3 V at the max. frequency. You need to set the gain
to -0.50 and the zero offset to 80%.
