I’m getting the 50174 “workobject don’t connected to conveyor” error, suggesting me that I need to check if I miss “WaitWObj”, and if I execute “DropWObj” before the end of coordination.

But I actually have it, in fact i’m trying everything this video tells me:  
[https://www.youtube.com/watch?v=x3e0-\_KiiQ0](https://www.youtube.com/watch?v=x3e0-_KiiQ0)

This is my fourth try and I’m always stuck at the same point, when the robot moves to the piece and tries to do the auto-path it stops and then sends me the error.

I did everything as the video says and I can’t get rid of this error, tried different conveyor speeds, tried duplicating WaitWObj action _(that caused another kind of error, probably because it should not be duplicated)_ and I’m starting to think that it could be a limitation of the controller or something like that… _(I’m doing everything virtually, no physical controller nor robot involved)_

I’m operating with the IRB120 and Robotware 6.02.1029

Someone could help me or knows something??  
Here is the unpack & go file:

Thanks in advance.

Try this.

PROC Path\_10()  
MoveL Target\_10,v1000,z20,MyTool\WObj:=wobj\_cnv1;  
MoveL Target\_20,v1000,z10,MyTool\WObj:=wobj\_cnv1;  
MoveC Target\_30,Target\_40,v1000,z10,MyTool\WObj:=wobj\_cnv1;

MoveL Target\_70,v1000,z10,MyTool\WObj:=wobj\_cnv1;  
MoveAbsJ pAbsHome,v1000,fine,MyTool\WObj:=wobj0;

ENDPROC
