Why is it not possible to set noise reduction in an ATV61 or ATV71 drive?

The noise reduction parameter cannot be set to YES for larger size ATV71 or ATV61 drives.
The range of drives that does not have this function are (D55M3) 75 HP and larger at 230 VAC and the (D90N4) 125 HP and larger at 460 VAC.
This is explained in the programming manual where the noise reduction parameter (code nrd) is explained.
