Detailed instruction of parameters
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
inverter 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:

-10V
Al3
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
Note: AI1 supports 0–10V input and AI2
supports 0–10V or 0–20mA input, when AI2
selects 0–20mA input, the corresponding
voltage of 20mA is 10V. AI3 can support the
output of -10V–+10V.
Setting range of P05.32: 0.00V–P05.34
