RobotStudio event

Paint robot on track

When I configure base frame (0,480,508.7) for robot IRB5403 on track T5403, Robot is moving by points but if I check axis of robots they have not the same values as real robot. Difference is exact as base frame.  If we leave base frame in (0,0,0) axis are correct but the points in RobotStudio are not showing on right position.
What should we do to solve that problem?
