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.

To handle this the 5226 controller needs to be aware of I/O to allow the Pathfinder system to run shear operations. If the machine configuration does not have Shear Forward and Shear Reverse outputs to control the shear then the 5226 will know it's a manually shear. This will put the shear operation into a separate control. Once in a manual shear operation the controller will move all axes(besides the shear) like normal, but there will be no need to press a pedal once everything has stopped moving. Once everything has stopped the user can remove the manual shear off its home limit which tells the 5226 that the operator has started the manual shear process. The user is now allowed to use the shear as needed and once done the user will put the shear back on the home limit and a press of the pedal will complete the operation to allow the user to move on to the next operation. If the pedal is pressed before the shear has returned to its home limit or before the shear ever left its home limit the controller will halt and throw error 378 Illegal Pedal Press During Manual Shear.

If the input Manual Shear Parked Position has been added to the configuration then additional features can be used. Once defined the same basic logic is still used, but if the user puts the shear on the Parked Limit and the next step is a shear operation, the controller will allow the process to continue. This is mainly used in slitter mode or one step when there are going to be multiple shear steps. This allows the user to not have to return the shear to the home position every time, so they can keep moving the shear back and forth for every cut programmed into Pathfinder.
