VC3-300

I tried to adjust the belt tension for the last hours, but somehow I can't get behind whats causing the first hump at around 50Hz in the belt tension. The tension is pretty strong (much more than before mounting FMMM and new belts). Also, the resonance on X is much higher than on Y. Could you please help me interpret the problem? (at least I think there is a problem)

OK thank you. But any idea where the first hump comes from? Sadly I haven't saved my old resonance tests but I can't remember them being there.
