29.2.3 Stored Stroke Check 2 (G22, G23)
An inhibition area can be specified inside or outside an area set by
setting screen or by program. Command distance from the machine
coordinates zero point for limit positions. This function is valid after
manual reference point return right after the power on. When
specifying the limits with program, limits or axes X, Y, Z can be set.
The inhibition area can be changed according to the workpiece. The
parameter decides whether the inhibition area is outside or inside the
specified area.

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.
