Actual measurement of AI1 voltage value, stored in function parameters
AC-02
Given AI1 voltage signal (about 8V)
For AI1 and AI2, it is recommended to use 2V and 8V as the calibration
point pair AI3. It is recommended to sample -8V and 8V as the correction
point.
When AI2 and AI3 are corrected, the actual sampling voltage viewing
positions are U0-22 and U0-23 respectively.

This set of function codes is used to correct the analog output AO.
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 target voltage is the theoretical output voltage value of the inverter.
The measured voltage refers to the actual output voltage measured by an
instrument such as a multi-meter.
7-1 Fault alarm and Solutions
FAULTS AND SOLUTIONS
When the inverter fails during operation, the inverter will immediately
protect the motor from output, and the inverter fault relay contact will act and
display the fault code on the inverter display panel. Before seeking service,
users can perform self-checking according to the tips in this section to
analyze the cause of the fault. If the fault cannot be solved, please seek
technical support from our company or product agent.
