Mechanical Unit Conflict in the simulation

LBPAL3

Hi All,

I created a robot setup with the following mechanical units.
IRB1520ID_4_150__02 robot
IRBP_A750_D1450-H900_M2009_REV1_01 Positioner
And a custom made linear rail powered by ABB Motor MU100 with gearbox.

I think I had everything setup properly but when I try to move the robot along the points that I created it throw the "Mechanical Unit Conflict" error. Plesae find attached photo and robot pack an go below.

One thing I notice I might be doing it wrong is the work object as it move along with the linear rail. It should only move along with the positioner and I couldn't find a way to correct this as well. (when I move linear rail all the robot target move along with the linear rail)

Thanks in advances for someone who can help.
