The setting of the AI curve is actually to set the scale relationship between the analog
input voltage (or the analog input current ) and the corresponding frequency setting .
When AI signal is as frequency reference，100% of the voltage or current analog input
corresponds to the percentage of relative (Max. Output Frequency F0.07). For 2 points
style curve setting and parameters description, please see below figure，（Curve 2、curve
