Note: By default, AI2 is assigned to #1 inverter
unit, and AI3 is assigned to #2 inverter unit. If
you want to change the configuration, see
section 5.2 for details.
AI2 is set by the control terminal AI2, AI3 is set
by control terminal AI3.
The function codes define the relationship
between the analog input voltage and its
corresponding set value. If the analog input
voltage exceeds the set minimum or maximum
input value, the VFD uses the minimum or
maximum value.
When the analog input is the current input, the
corresponding voltage of 0–20 mA is 0–10 V. In
different cases, the corresponding value of
100.0% is different. See the application for
detailed information.
Input filter time: This function code is used to
adjust the sensitivity of analog input. Increasing
the value properly can enhance the
anti-interference of analog, but weaken the
sensitivity of analog input
Note: AI2 supports 0–10 V or 0–20 mA input.
When AI2 selects 0–20 mA input, the
corresponding voltage of 20 mA is 10 V. AI3
supports the input of -10V – +10V.
