AI1 is set by the analog potentiometer, AI2 is set
by control terminal AI2 and AI3 is set by control
terminal AI3. The function code defines the
relationship between the analog input voltage
and its corresponding set value. If the analog
input voltage beyond the set minimum or
maximum input value, the VFD will count at the
minimum or maximum one.
When the analog input is the current input, the
corresponding voltage of 0 – 20mA is 0 – 10V.
In different cases, the corresponding rated value
of 100.0% is different. See the application for
detailed information.
The figure below illustrates different applications:
