Function
Use this parameter to enter the smaller machine coordinate value that
determines the location of programmable zone 3. This value may be
altered on the control, if desired, by using the programmable zone table or
by the proper programming commands. The area defined as
programmable zone 3 limits axis motion according to the position of the
axis when the zone is activated.
