2.3.3 Stroke Check 2
General
Three areas which the tool cannot enter can be specified with stored
stroke check 1, stored stroke check 2, and stored stroke check 3.
Figure 2.3.3 (a) Stroke check
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.
Stored stroke check 2 (G22, G23)
Parameters (Nos. 5222, 5223) or commands set these boundaries.
Inside or outside the area of the limit can be set as the forbidden area.
Parameter OUT (No. 5200#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
forbidden 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:
