Conveyor Tracking troubleshootings

Hi all,

I face a problem since 3 days. I tried to solve it, but no success.
I have a robot 140, rotated around axis Y 180 degree. Positioned World Coord Z=1550 mm.
I want to have a conveyor tracking moving on axis Z 100mm. (from top to bottom, vertical)

I create the conveyor everything is moving, BUT not the robot tool in Z. Its moving in world coord in X direction. WHYYYYYYY?

I have no idea.

Here is my Project Packed&GO
webwiz/5071/0710night_conveyor.rar

Can tell me someone what`s wrong?

I made based on the tutorial:
http://www.robotstudio.com/tutorial/12/ConveyorTrackingSetupandProgramming1024.html

only that I changed the base frame, The task frame was`t moved.
