Changes made for Pathfinder 5226 controllers.

Winter mode is a new feature that is to be used as its name implies, during cold weather. On some hydraulic machines that are using VFD's to control a couple of axes the machine needs more horsepower to run ats its traditional speed when it’s cold. The problem is that this horsepower can end up exceeding what the motor is capable of supplying. This will trip the drive consistently and make the machine un-usable until the hydraulic fluid can warm up to be able to run as normal.

The proposed solution is to have 2 new operator parameters. They are 766 Winter Mode Enabled which will enable/disable the feature and 767 Winter Mode Max Speed which is the limit of analog signal the controller will send to the drive when Winter Mode is enabled. This max speed is always the limit if Winter Mode is on. On the other side is that other speeds options can be used like throttle, safe and operation step speeds as long as they don't exceed the Winter Mode limit. This should keep the drive from tripping in cold weather, but also keeps open other advancements to Winter Mode.
