AI1 is set by the keypad potentiometer, AI2 is
set by control terminal AI.
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 0–20 mA is 0–10V.
In different cases, the corresponding rated
value of 100.0% is different. See the
application for detailed information.
Input filter time: this parameter is used to
adjust the sensitivity of the analog input.
Increasing the value properly can enhance
the anti-interference of the analog, but
weaken the sensitivity of the analog input
