Changes made for Pathfinder 5226 controllers.

The 5226 controller has the capability to talk to drives through the Ethernet I/P protocol to control an axis. Ethernet I/P uses implicit messages to receive constant information from the drive like feedback and to control messages to tell the drive to do something like move to a position. The protocol then uses explicit messages to directly change or request a parameter in the drive. One of the drives added was the Indra Drive CS. For more information refer to:

SCN 4236 5226; Add New Ethernet I/P Driver IndraDriveCs

When the user disables limits to move the backgauge the controller takes a large default position to tell the drive to move to. This is essentially a target that the backgauge cannot reach without hitting a physical limit. The problem is that the target is even bigger than the allowed travel range in the drive so an error is always thrown when trying move the backgauge with limits off.

The solution was to make sure the default target in the controller is within the max travel range of the drive. This ended up being 250 inches.
