29.2.3 Stored Stroke Check 2
Two areas which the tool cannot enter can be specified with stored
stroke check 1, stored stroke check 2.
When the tool exceeds a stored stroke limit, an alarm is displayed and
the tool is decelerated and stopped.
When the tool enters a forbidden area and an alarm is generated, the
tool can be moved in the reverse direction from which the tool came.
29.2.4 Stroke Limit Check Before Movement
This function calculates the movement end point at the start of
movement in a block, during automatic operation, based on the current
machine position and the specified amount of travel, to check whether
the end point falls within the inhibited area for stored stroke limit 1, or
2. If the end point falls within an inhibited area, movement for that
block is stopped immediately upon the start of movement and an alarm
is issued.
