So the drives have 5 options in motor codes that have no corresponding numbers in the manual where there is a list of motor codes. We just kept changing codes until it sounded good. And one of them seemed a lot nicer than the rest then we auto tuned and the motor is quiet. It holds position and works perfect. So I'll just use it. And if it breaks so be it.
I emailed yaskawa. They were not to much help lol.
