Function codes B3-12 ～ B3-19 are used to correct the error between the actual output value
of AO analog quantity and the theoretical output value. It has been calibrated at the factory,
and generally does not need to be calibrated at the application site. When restoring the fact-
ory value, it will be restored to the factory calibration value.
The target voltage refers to the theoretical output voltage value of the inverter. U1-37 and
U1-38 correspond to the target voltages of AO1 and AO2 respectively. The measured voltag-
e refers to the actual output voltage value measured by instruments such as a multimeter.
During calibration, after inputting the target voltage and the measured voltage in the corres-
ponding function code, the inverter will automatically correct the output value.
Group B4: Master-slave control parameters
Master-slave control refers to the data exchange between two or more inverters through poi-
nt-to-point communication, so as to achieve the effect of speed synchronization or current
balance between multiple inverters, and is often used in multi-drive occasions. For example,
sand excavators, coal mine belt conveyors, etc. Please correctly set the inverter communica-
tion group P8 group before use.
When using 485 communication for master-slave control, the inverter can no longer commu-
nicate normally with the host computer using 485 communication, otherwise the system will
work abnormally. There are the following precautions when using master-slave control:
Master and slave directions are determined
When master-slave control and speed synchronous control is required, make sure that the
actual running directions of the master and slave motors are the same before running.
