My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
If the frequency converter is selected according to the motor rated current, then the motor current exceeds the rated current, the inverter will become overcurrent protection
In this case, that is, when the inverter began to select the amount of time to stay the lack of the same power, inverter general type than the fan pump type current capacity of a high grade
If the inverter selection is no problem, then please see whether the inverter is working temperature is too high, too high will cause the electronic components to resist the decline in current.
First, check the inverter to work the ambient temperature, the second Please check the inverter fan is damaged, clean down the inverter fan channel and fan to see if there is no plug
Motor current when the current 10A this has no effect on you, the rated current is 31.4A, your inverter is selected how many W, is the fan pump type or universal?
Now the motor operating current reached 34-35A, more than the rated current, then the motor may have two problems, one is the motor leakage powerful, and in a motor is overload, resulting in increased current
For your situation about the summary of recommendations:
First, check whether the motor overload and whether the leakage exceeded,
Second, check and clean the inverter fan, if the room temperature is high, add the external fan to the inverter cooling
Third, if none of the above, then please check the inverter module is burned, replace the module
Fourth, if the inverter is no problem, then the motor and load the problem, if the motor problems are not resolved, then only re-select the inverter, please select the time to increase the margin
