A customer has an SPD controller that sometimes halts after each part and generates a new Bundle ID. Production records indicated it was halting for an out of orders condition. A new ID is generated on an Order change or when it runs out of orders.

The customer sent their settings and it was determined that they are configured to use the Hole Correction feature.

On a shear only controller, which they have, the next part is queued 10 inches before the current part gets cut. In the simulation using their settings I was able to determine that the controller was using the wrong resolution (input vs output) for this test and it was queueing 0.56" inches before the current part got cut. If the line runs fast enough the run task may not have time to queue the next part.

A second issue was discovered. The Hole Correction feature can cause the part to get cut before the queue expects it. The Hole Tolerance needed to be added to the 10 inches so that the even if the target got adjusted to be cut sooner, the queue still had at least 10 inches before the cut to add the next part.
