Stop programpointer without stopping Robot

Mikael_ala

Hi

I'm trying to optimize an Glue robot. Between every glue-string there is an Checkbead to check if the Glue-string was ok or not.
This takes cycletime, approx 1 sec per bead.

Been trying to optimze this and not to stop the robot inside the Checkbead routine but without success. 

The problem is that the robot stops in an Waittime/inpos instruction. This instruction is used cause the program pointer jump's so much forward in the rapid code. If we don't use the
waittime/inpos instruction the Program pointer resets the bead so we don't get any glue.

My question is if there is any instruction I can use to stop the program pointer without stopping the robot. Anyone who had similar problems?


Here is the code in the "work-routine"

Proc Myworkroutine()

        Toolchange Doser511;

        PrepareEquipment Doser511,HomeDoser511;

        Doser511AutoPurgeSch;

        !

        MoveAbsJ HomeDoser511,vmax,fine,Doser511TCP;

        !

        MoveJ ToBS1_10,v2000,z50,Doser511TCP\WObj:=BSStn020;

        PrepareBead bdbead 1_1;

        MoveL ToBSdb30,v2000,z50,Doser511TCP\WObj:=BSStn020;

        !

        DispL\ON,BSdb_Start,v150,bdbead1_1,z5,Doser511TCP\WObj:=BSStn020;

        DispL\OFF,BSdb70,v150,bdbead1_1,z5,Doser511TCP\WObj:=BSStn020;

        MoveL BSdb71, v150, z50, Doser511TCP\WObj:=BSStn020;

        CheckBead bdbead1_1;

        PrepareBead bdbead2_1;

        DispL\ON,BSdb50,v150,bdbead2_1,z5,Doser511TCP\WObj:=BSStn020;

        DispL\OFF,BSdb60,v150,bdbead2_1,z5,Doser511TCP\WObj:=BSStn020;

        MoveL BSdb70, v150, z50, Doser511TCP\WObj:=BSStn020;

        CheckBead bdbead2_1;

        PrepareBead bdbead3_1;

        DispL\ON,BSdb73,v150, bdbead3_1,z5,Doser511TCP\WObj:=BSStn020;

        DispL\OFF,BSdbEnd,v150, bdbead 3_1,z5,Doser511TCP\WObj:=BSStn020;

        MoveL ToBSdb30, v150, z50, Doser511TCP\WObj:=BSStn020;

        !

        CheckBead bdbead 3_1;

Try making and using your own StoppointData, read up on it in the manual.

Check out TriggL and MoveLSync. Also, maybe a background task to be checking IO in the background and the motion task just sets a signal to check and keeps moving.

MoveLSync....Good call Soup.

Mikael_ala

I used the MoveLSync an created a new routine were I set an bool and with that bool I used a while loop inside the Checkbead routine to "catch" the PP inside the while loop until I reached my MoveLSync pos. 

seemed to work. Thanks for the help guys.

No problem, glad it worked. Thanks for the shout-out @lemster68
