6.4 STROKE LIMIT CHECK BEFORE MOVE
During automatic operation, before the movement specified by a given
block is started, whether the tool enters the inhibited area defined by
stored stroke check 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 check 1, 2, or 3, an
alarm is issued. (See the examples below.)
Example 1)
The tool is stopped at point a according to stored stroke
check 1 or 2.
Immediately upon movement commencing from the start
point, the tool is stopped to enable a stroke limit check
before moving to be performed before movement.
