The coordinate values of the points defining the software overtravels are
set in AMP by your system installer. This overtravel can only be disabled
by your system installer in AMP. If your system installer has enabled the
software overtravels, the control is not allowed to exit the area defined by
the software overtravels.

Your system installer selects values that represent a maximum and a
minimum value in the form of coordinate values for each axis. These
coordinate values define points on the machine coordinate system. The
axes are not allowed to move past the coordinate value representing the
maximum and minimum value on each axis. This limited range of motion
is referred to as the software overtravels.
