These parameters are used to correct the AI 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. For
details, refer to U0-21, U0-22 and U0-23.
During correction, send two voltage values to each AI terminal, and save the measured values
and displayed values to the function codes U0. 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 AI1 as an example. The on-site correction is as follows:
• Send a voltage signal (approximately 2 V) to AI1.
