Changes made for Pathfinder V4/V5 and 5226 controllers.

A shear is an additional option on some folding machines that can be used to cut material at certain lengths. This type of axis is usually automatically controlled. Some shears on machines are now setup to be used manually by an operator. This is done by having the shear locked into a position on top of the machine instead of on the left or right parallel to the clamp surface. When the operator wants to use the shear they can bring it down from the top and latch it onto the clamp surface. It can then be moved back and forth by the operator manually to cut the material.

For more information refer to SCN 4555 5226; Added Manual Shear Logic.

The original implementation still used the old logic that if the shear is on it's home limit the bending beam can move. Based on how the machine is mechanically this is no longer the case and the shear must be on its parked position to move the bending beam. To handle this Error 397 Manual Shear Must Be Returned to Park Position was added to the controller and Pathfinder UI. The controller will not let the bending beam move unless the shear is on its parked limit and if not this error will be thrown.
