Changes made for Pathfinder 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.

SCN 4555 5226; Added Manual Shear Logic

One logical problem that was originally overlooked is that the bending beam can not move when the shear is not in its upright/parked position. The clamping beam on the other hand is allowed to move if the shear is on its down home limit. With the clamp able to move with the shear home limit on it allows the operator to use the slitter mode in Pathfinder that does multiple shear steps in a row. So if the next operation is not another shear operation to account for slitter mode then the shear must be returned to its park position to allow the next step to use the bending beam. If the shear does not get to the park position and a confirmation pedal does not occur then the system will never continue on to the next step.
