Analysis of the reasons for overcurrent tripping during inverter operation

2017-04-15View Original

Thread Content

A pump that automatically adjusts the frequency of the inverter based on flow rate; after an overcurrent trip occurs, checking the trend shows that the inverter frequently changes speed. Could such frequent speed changes cause an overcurrent trip?

I’ve encountered cases where the determination was problematic

Check the PID settings of the instruments, verify whether there are any severe fluctuations in flow rate within the process, and finally check the frequency converter.
