A request was made to make retrofitting Beck controllers on Viper systems easier.

These systems initiate Rollformer and Feeder motion with a Run signal. They create part separation through the Rollformer with a Delay After Shear like feature that slows the Feeder. We cannot use our Run signal to initiate material motion. That function belongs to the material motion outputs.

This requires us to provide three states of motion in the run mode for the Feeder, Stopped, Slow and Fast. If the Feeder is in Slow or Fast, the Rollformer on the Viper needs to be in motion.

The chosen solution was to allow the Delay After Shear feature to use the Slow speed to create the part separation rather than Stopped. This setup is available when our open loop motion outputs are provided to control material motion.

A new setup has been created called Delay After Shear Mode. It has two settings, Stop and Slow. It defaults to Stop, which causes Delay After Shear to Stop for the delay as it did before this change. Slow causes Delay After Shear to Slow for the delay.

One exception to this is if there is a Bundle Stop Delay that is active at the same time. If the part in question initiates the Bundle Stop, Bundle Stop takes precedence and the controller will stop for the delay instead.
