E.g:
The voltage of analog input AI1 fluctuates around 5.00V, the fluctuation range is
4.90V~5.10V, the minimum input of AI1 is 0.00V corresponding to 0.0%, and the maximum
input of 10.00V corresponds to 100.%, then the detected AI1 is set at 49.0. Fluctuations
between %~51.0%.
Set AI1 to set jump point A6-24 to 50.0%, and set AI1 to set jump width A6-25 to 1.0%.
When AI1 is input, after hopping function processing, the corresponding AI1 input
corresponding setting is fixed to 50.0%. AI1 is transformed into a stable input that eliminates
fluctuations.

This set of function codes is used to correct the analog input AI to eliminate the effects of zero
offset and gain on the AI input. The function parameters of this group have been corrected
at the factory. When the default is restored, it will be restored to the factory-corrected value.
Generally no correction is required at the application site.
The measured voltage refers to the actual voltage measured by a measuring instrument such as
a multimeter. The display voltage refers to the voltage display value sampled by the inverter.
See the U0 group AI correction voltage (U0-21, U0-22, U0-23) display.
During calibration, input two voltage values for each AI input port, and respectively input the
value measured by the multimeter and the value read by the U0 group into the above function
code, the inverter will automatically perform the zero offset of the AI. Correction of the gain.
For the case where the user's given voltage does not match the actual sampling voltage of the
inverter, the field calibration method can be used to make the sampling value of the inverter
