Various Closed Loop models that support Two Encoder Feed to Stop will now also support a selective option.

This option has been added to support machines that have a disparity between the physical location of the line encoder and where the feeder (rollformer) has enough grip to jog the material. The tailout switch is typically located with the line encoder. The issue is that when the material is sensed, the loop is closed around the line encoder. If the feeder does not yet have enough grip to feed the material, Max Slip errors occur.

This new mode offers a solution. While jogging, the feeder motor is operated in an Open Loop fashion. A command proportional to the Max Velocity at 10V setup is sent to the drive while jogging. When halted, the loop and drive are disabled to prevent issues that would arrise if the material is halted while the feeder has no grip. When in Full Auto, the motor and loop are operated in standard Two Encoder Feed to Stop fashion.

The models, where available, and the switch settings required to configure this new mode are defined in the Switch Settings document.

An Unlicensed Model can now be configured in the Model Codes so that the controller powers up in this model.

There is one Model for each software project.
