    It is wired as delta, what do you mean with wired correctly at the motor end? V is V, W is W, U is U.
    Yes its a 2 pole motor. I checked all connections several times and do also a trough check with multimeter.
    Max current is set to 8000.

    I saw in different videos nobody needs torque compensation for starting motor with load.
    It seams that one phase has not enough power and causes the motor stuttering under load. So I think something is wrong with my Vfd.

    I just meant to check if it is wired delta. If you have an oscilloscope and current clamp you could do some checking but you could be right and the inverter is maybe faulty. Is it new and a recent purchase? See what the seller has to say about it.

    It´s a new one, I already contacted the seller, let´s see what he is saying.....Chinese seller.....
    Unfortunately I didn´t have a oscilloscope and current clamp. But the company in the neighborhood of my company have the equipment, I ask them if they can check for me, they are machine builders and familiar with such stuff.

    Attached you can find my settings. Maybe you can find a wrong value.
