Your instructions show P25 as 'not listed' and my instructions show that as the number of poles. 0 = 2 poles, 1 = 4 poles, 2 = 6 poles. Luckily you have set yours to 0 which is 2 poles, although P21 is different and asks for 'rpm for 50 Hz', which I guess is another way to calculate number of poles.

I can't see anything else wrong, so suspect it is faulty. The Chinese sellers often want some evidence of the fault so your video should help there, plus you have tried 2 different motors. I would wait for them to respond and not dive into asking a company to look at it. If the seller thinks you have opened it up they may not refund you.

I had a invertor arrive faulty a few years ago (it went bang when I wired it up to the mains - no motor had been fitted) and they wanted to see a photo of the wiring. After showing them the photo they asked me to send it back and they sent another. Good luck.
