Zone 2
Tool tip can not
enter zone 2
For details on how the control reacts to entry into a prohibited area, see
page 12-13.
Programmable zone 3 can define an area which the tool cannot enter or
an area the tool cannot exit. The current tool location determines when
programmable zone 3 is made active. Generally, zones are used to protect
some vital area of the machine or part located within the software
overtravels.
Important: Programmable zones are defined using coordinates in the
machine coordinate system. They are not affected by any changes in the
work coordinate system, including external offsets.
WARNING: Programmable zones only protect the tool tip
from entering the zone (as determined with the currently active
tool length offset). They do not protect other moving members
from collision with objects in the programmable zone’s
boundary.
