conveyor tracking: working area problem

memphiss

I have a problem of tracking. I have a linear conveyor, robot tracking its moving (left to right direction).

  My working frame  is 1 Meter width. If robot do movment (for example,welding) from right to left,all area is reachable; But if I program welding routine to start from most left corner to right, robot

will stop and tell errors.

  Is it because of tracking parameter settings not so good? I guess I need to change StartWinWidth=0.2 or something like this?

        -Unit "Qtrack1" -CommandType "CountsPerMeter" -Value "1858"

      -Unit "Qtrack1" -CommandType "SyncSeparation" -Value "1.75"

      -Unit "Qtrack1" -CommandType "QueueTrckDist" -Value "0.0"

      -Unit "Qtrack1" -CommandType "StartWinWidth" -Value "0.5"

    Could anyone help me out? Very appreciated
