unit value of the inverter.
Since the using methods of curve 1 and curve 2 are identical, Curve 1 is described as an example here.
Both curve 1 and curve 2 can be used in process open loop analog frequency reference, and the running
frequency of the inverter can be determined by the analog values AI1 and AI2. The conversion
relationship between analog value and setup frequency is as shown in the figures below:
