Function Code Parameter Name Setting Range Default
F5-09
Max. FMP output frequency 0.01 to 100.00 kHz 50.00 kHz
This function parameter sets maximum pulse output frequency when FM terminal is used for
pulse output.
Function Code Parameter Name Setting Range Default
F5-10
AO1 zero offset coefcient -100.0% to 100.0% 0.0%
F5-11
AO1 gain -10.00 to 10.00 1.00
F5-12
AO2 zero offset coefcient -100.0% to 100.0% 0.00%
F5-13
AO2 gain -10.00 to 10.00 1.00
These four function parameters generally correct zero offset of analog output and output
amplitude error. They can also dene required AO curve.
Zero offset coefcient 100% of AO1 and AO2 corresponds to 10 V or 20 mA. You can calculate
the gain and the zero offset coefcient from the following formulas:
K
=
(Y1 – Y2) x Xmax
(X1 – X2) x Ymax
b =
(X1 xY2 – X2 x Y1)
(X1 – X2) x Ymax
In the formulas:
● "b" represents zero offset.
● "k" represents gain.
● "X" represents output frequency.
● "Y" represents actual output of the AO.
● " Xmax " represents max. output frequency (determined by F0-10).
● "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
zero offset coefcient as follows:
K =
(8 – 4) x 50
(0 – 40) x 10
=
–0.5
b =
(0 x 4 - 40 x 8)
(0 - 40) x 10
= 80%
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:
AO1 output signal Corresponding Max. Output (Ymax)
Voltage 10 V
Current 20 mA
