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.

For background on the overshoot parameter logic refer to:

SCN 4619 - 5226; Added Backgauge Overshoot Distance Logic

All of the overshoot logic on the 5226 was tested on a machine configuration that had no spring finger on the machine. When there is a finger the 5226 will adjust targets for the backgauge and visual feedback to account for when the finger is active. A bug was found with the overshoot distance on a machine that has a spring finger in which after the first move the backgauge will no longer overshoot when the finger is active.

The bug ended up being a calculation for the backgauge target for the overshoot move to ignore the fact that there is a finger active. The solution was to make sure that the finger offset distance is taken into account when deciding if the backgauge needs to overshoot.

The new 5226 rev G boards have a different processor chip than previous revs. To differentiate between the G's and the rest it was decided to make the G board software be version 5 and the B's, E's and F's will stay at 4. This will make it easier to find out what type of board it is in the field by looking at the version number in Pathfinder.
