Important: These areas are measured from the machine coordinate zero
point to the extremes of the fixture encompassed by the zone when the
machine is at home. The machine coordinate system zero point and
machine home are frequently not the same point on the machine. Machine
home is a fixed mechanical position established by the homing sequence
off hardware homing switches. The machine coordinate system zero point
is established in AMP and referenced from the machine home point (see
chapter 11 for details). Refer to your system installer’s documentation for
information regarding the location of machine coordinate system zero. For
interference checking to function properly, both processes must have the
same zero point, but they can have different home locations.
