Basically it is a parameter that will "offset" the index pulse.

Haas has a value that all machines need to be. Like 0.1 inches from switch to encoder index. In the grid offset parameter you enter the number of pulses to "shift" the index pulse to get the 0.1 > > On high pitch ball screws the location of the index pulse could move your zero a lot. They did not want people messing with the encoders and causing other problems so they have the parameter. Anyways That is my 2 cents I like it. It would be useful as we could realign the encoders in software should they get out of sync! -Tom |
