Function codes B3-00 ～ B3-07 are used to correct the error between the actual input value of
the AI analog quantity and the AI value displayed by the inverter, so as to eliminate the influ-
ence of the zero offset and linearity of the AI input port. This group of functional parameters
has been calibrated before leaving the factory, and the user can calibrate it again according
to the on-site usage, but the parameters will be restored together when restoring the factory
defaults. Calibration is generally not required at the application site.
The measured voltage refers to the actual voltage measured by a multimeter and other mea-
suring instruments, and the displayed voltage refers to the displayed voltage value sampled
by the inverter. The displayed voltages of AI1 and AI2 correspond to function codes U1-19
and U1-20 respectively.
When calibrating, input two voltage values to each AI input port, and respectively input the
value measured by the multimeter and the value read by the U0 group into the above functi-
on codes, then the inverter will automatically perform AI zero offset and calibration. Gain
correction.
