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.
 The inverter offers three groups of analog input signal. They are analog input
terminal AI1, AI2, and pulse. Users can define input /output curve of each channel.
Totally, you can define three curves.
 The analog input of AI1 and AI2 can be voltage (0~10V) or current (0~20mA),
selected by the switches on the control board. (Switching SW1 at place 1 means
OFF, it corresponds to 0-10V. If SW1 is ON, it corresponds to 0-20mA.)
 Through setting P4.01~P4.04, P4.06~P4.09 and P4.11~P4.14, can defined two
characteristic linear curves. The positive and negative function is shown in
Fig.5-4-1.
