initial position of a part (motor animation)

[Madda]

Hello, everyone. I built a pro/engineering wildfire 4.0 assembly and defined the mechanism in such a way that through a table read from the outside the motor and screw connected to it rotate, and instead the transla cursor.
the problem is that when the animation starts, the slider leans on the frame(image 1), I would like it to be in the center (image 2). How can I do that?

Thank you so much!

I reversed the attachments...I would like the initial position to be as in image 1...

I don't understand what you have to do but if I have to give you advice like that to the Czech... you have to set the initial position in the assigned bond. . . Besides the bond type you will have the position to assign on a menu to the side. .

--edit--

Maybe I get it.. .

you have to do what I told you before...fixing as an initial position the coincidence or proximity of the surfaces of the image you post...if you turn the file I try to take a look. .
