Note 1:

Min/Max virtual value of analog input is the Min/Max virtual value of the input signals. If the actual value
input is smaller than min value, the min value will be treated as the Min virtual value of analog input. If the
actual value input is greater than the max value, the max value will be treated as the Max virtual value of
analog input. The max virtual value of analog input must be greater than the min.

Physical value corresponding to virtual value of analog input: The physical value can be reference frequency,
rotate speed, or pressure, etc.
 This series of 35R5GB and above models of inverters are provided with four groups of analog input signals:
analog input terminals AI1, AI2, AI3, pulse; 3004GB and below models of inverters are provided with three
groups of analog input signals: analog input terminals AI1, AI2 and pulse. Users can define input / output
curve for each channel, and can define a total of four groups.
 AI1 and AI2 input signals can be 0 ~ 10V voltage signals, or 0 ~ 20mA current signals, are selected by the
users through toggle switch on the control board (SW1 toggle switch is at 1 position, which means when it is
OFF, it corresponds to 0-10V, while when it is on, it corresponds to 0-20mA). The AI3 input signal
corresponds to-10V ~ 10V voltage signal.

Through setting P4.01~P4.04, P4.06~P4.09 and P4.11~P4.14, P4.16~P4.19 can defined two characteristic
linear curves. The positive and negative function is shown in Figure.5-4-1.
