2. PREPARATIONS FOR OPERATION
76
When the tool exceeds a stored stroke check, 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.
Parameters (Nos. 1322, 1323) or commands set these boundaries. Inside
or outside the area of the check can be set as the forbidden area. Parameter
OUT (No. 1300#0) selects either inside or outside as the forbidden area.
In case of program command a G22 command forbids the tool to enter the
forbidden area, and a G23 command permits the tool to enter the forbid-
den area. Each of G22; and G23; should be commanded independently of
another commands in a block.
The command below creates or changes the forbidden area:
G 22X_Z_I_K_;
A(X,Z)
X>I,Z>K
X–I>ζ
Z–K>ζ
B(I,K)
ζ is the distance the tool travels in 8 ms. It is 2000 in least
command increments when the feedrate is 15 m/min.

G 22X_Y_Z_I_J_K_;
ζ is the distance the tool travels in 8 ms. It is 2000 in least
command increments when the feedrate is 15 m/min.
