These parameters are used to correct the VI to eliminate the impact of AI zero offset and
gain.
They have been corrected upon delivery. When you resume the factory values, these
parameters will be restored to the factory-corrected values. Generally, you need not perform
correction in the applications.
Measured voltage indicates the actual output voltage value measured by instruments such
as the multimeter. Displayed voltage indicates the voltage display value sampled by the AC
drive.
During correction, send two voltage values to each AI terminal, and save the measured
values and displayed values to the function codes PF.00 to PF.03. Then the AC drive will
automatically perform AI zero offset and gain correction.
If the input voltage and the actual voltage sampled by the AC drive are inconsistent,
perform correction on site. Take AI as an example. The on-site correction is as follows:
1) Send a voltage signal (approximately 2 V) to AI.
2) Measure the AI voltage and save it to PF.00.
3) View the displayed value of b0.21 and save the value to PF.01.
