During automatic operation, before the movement specified by a given
block is started, whether the tool enters the inhibited area defined by
stored stroke limit 1, 2, or 3 is checked by determining the position of the
end point from the current position of the machine and a specified amount
of travel. If the tool is found to enter the inhibited area defined by a stored
stroke limit, the tool is stopped immediately upon the start of movement
for that block, and an alarm is displayed.
WARNING
Whether the coordinates of the end point, reached as a
result of traversing the distance specified in each block, are
in a inhibited area is checked. In this case, the path followed
by a move command is not checked. However, if the tool
enters the inhibited area defined by stored stroke limit 1, 2,
or 3, an alarm is issued. (See the examples below.)
