8. Input/Output parameter setting for analogue AI and AO current 4 - 20mA
Analogue 4 - 20mA input
Current inputs through AI2. Default current: 0 - 20mA. Short connect pin 2 & pin 3 of CN2.
To use 4 - 20mA signal to adjust frequency 0 - 50Hz, set parameters according to following:

Analogue 4 - 20mA output
AO1/AO2 can select current output, default: 0 - 20mA.
Short-connect pin2&3 on CN7 for AO1, and short-connect pin2&3 of CN8 for AO2.
To achieve 4 - 20mA output, please change bias and gain:
Output Ref. code Function Setting Meaning
AO1
F16.22 AO1 bias 20 AO1 analogue bias
F16.23 AO1 gain 80 AO1 analogue gain
AO2
F16.24 AO2 bias 20 AO2 analogue bias
F16.25 AO2 gain 80 AO2 analogue gain
