What does "EPCU" mean in a frequency converter?
But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!
This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory
This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment.
