point 1 voltage, the inflection point 2 voltage, and the maximum voltage must be increased in turn. AI
curve selection F4-33 is used to determine how the analog inputs AI1~AI3 are selected among the 5
curves.
A6-24 AI1 sets the jump point
A6-25 AI1 sets the jump range
A6-26 AI2 sets the jump point
A6-27 AI2 sets the jump range
A6-28 AI3 sets the jump point
A6-29 AI3 sets the jump range
The inverter analog input AI1~AI3 has the set value jump function. The jump function is to fix the
analog amount corresponding set value to the value of the jump point when the analog amount is set to
change in the upper and lower sections of the jump point.
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. Fluctuations between 49.0%~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
multi-meter. The display voltage refers to the voltage display value sampled by the inverter. See the U0
group AI correction voltage (U0-21, U0-22 and U0-23) display.
During calibration, input two voltage values ​ ​ for each AI input port, and respectively input the
value measured by the multi-meter 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 consistent with the
