As C Lau States the inverter requires information about maximum voltage, reference frequency, intermediate voltage, intermediate frequency, minimum voltage maximum - and minimum operating frequency, revolution@50 Hz etc. Besides I noticed the power input was labeled R, S and T, which should have been L and N. So perhaps you've got yourself a three phase input model?

Nothing wrong with the inverter, you can't just use the factory defaults, you have to go through all the various settings and set the voltages and currents as appropriate for the motor.. I've got two of these things and they work beautifully if you understand how to set the parameters.. The voltages and currents that the motor expects need to be set up (it doesn't care whether you are using delta or wye, as along as the appropriate voltage is applied.. Check pd141-147 for correct motor ratings

So what happened, did you get it working?

DJB HSI did a damn good rundown on one of these, the manuals crappy, watch his vid!!, big help

Its not a real HY for one. Real ones have alluminum heat sinks

You need set up inverter. I had the same. Once you select program and input value you need confirm by prog. to set. Your motor is 50 do not set to 400 because you blow motor or inverter.. go to cnc forum

You connect the earth from 220 V to the motor connector. I dont think that make sense.

As I can see from this video, you didn't even try to read user manual for these inverter, which describes errors, and yet you claim that it cannot provide 2.2kW of output power. I think you should first get to know something about VFDs and Induction motors, and then and only then give some lectures to people who actually make working VFDs and sell it.

Try setting the motor up as a Y configuration.

I have one... it works fine... if you know what you are doing..
