Hi there, we have a checkweigher with a conveyor and a box goes across the checkweigher it sends a signal of over or under. If its under it calls a subroutine to discard the box, if not it puts the box into a shipping box. Only problem is it sometimes puts the under weight box(somethings missing inside, quality error) Not sure what information may be missing from the program, or if the difference in the weights are not enough to trigger the robot/program correctly.

Also the weight of a complete box is 2.04lbs and when something is missing it only goes down to 1.96lbs. Not sure if that's too small of a weight difference or if maybe I should slow the conveyor down and let it register first and be able to fully send the signal to the robot.

Where is the throw variable being set?  Its hard to follow the images of the program as they do not appear to be in order.  If you could save the program onto a USB drive and then upload the .txt file that is created when you save it and upload here that would help me understand the program better and be able to help.

You can either save the program or you can backup the robot from the touch pendant onto a USB stick.  If you insert a USB stick and then click the little gear icon in the upper right when you are on the load program screen you will see backup to USB as an option.

We figured out that it was zeroing the throw away too soon.
