When G36 through G39 are commanded, these
setting data are automatically rewritten.
Therefore, the ON or OFF state ultimately
specified by G code commands or setting
function becomes effective.
The 1st pro-
hibited area is always in the CHECK ON
mode.
(6) Starting area check
When the tool is returned to the reference
point once manually or automatically after
the energization of the control, the area
check function is started immediately.
Therefore, if the reference point is in the
prohibited area, immediately, STROKE
LIMIT ERROR will be caused. In
this case, turn off the area check function,
and change the data.

When
the tool enters the prohibited area,
it stops just inside the boundary line, and
the control enters STORED STROKE LIMIT
ERROR state.
In this case, the tool can
only be moved manually in the return direc-
tion.
Displaying remaining distance
With this function, the distance between the
current tool position and the boundary of the
prohibited area in the X and Z directions
are displayed on the CRT . Refer to 4.3.4.6.

overlapping.
