How to specify the "Prescribed Displacement" for the given range?

Dear All,
I have a model with a multiple load (boundary conditions) about the 3D coordinate
Details are as stated below,
About X:
Translation : No
Rotation : +10/-5 deg
About Y:
Translation : No
Rotation : +3/-3 deg
About Z:
Translation : +3mm/-3mm
Rotation : +3/-3 deg
the above problem is based on displacement control.
I tried "Rigid Connector" option is doesn't responds to the rotation (some bug I believe) but does the displacement about the coordinate (just as Prescribed Displacement).
Now I have developed equation of motion for rotation along X, Y & Z and applying by using "Prescribed Displacement"
But, Now I am left with the Translation displacement condition about Z axis.
I am quite confused about how to apply the translation motion within the range of -3 to +3 passing through origin
any suggestion ?
or else how could I develop an equation for it !!! and combining the eq for rotation?
Please find the file attached and its done in 4.1 COMSOL version!!
any help please
Thank you
Kind regards
damo
