To be honest RoB if the OP can’t provide the required information then we may as well wash our hands of it. I can’t see a way forward with what we have.

To the OP:
If this is a turnkey project get the machine manufacturer in and stop wasting everyone’s time.

I also smile as I push the knife home.

Does it cost me anything to be polite?

Generally if all settings are correct an overload trip points to a mechanical problem, and a MCB trip points to an electrical problem. Does it have to be star/delta start, I would have thought a fan even up to this size it could be DOL.
