13.4 Automatic Operation Restart with BLOCK RESTART Condition
110
X=100, Y=70, Z=10.
3 rd part block: Hole machining and retraction to start position (G98) or to R-point (G99). In
this part block the start position is coordinate X=100, Y=70, Z=2.
At the end of all three part blocks the control stops in single block mode. If the canned cycle is
programmed with repetition count L the above part blocks are repeated.
2
nd
case: Interrupting and restarting canned cycle in the course of positioning in the selected
plane
If in the sample cycle the movement is interrupted during moving to position X=100, Y=70
and it is moved to the start position of the block by means of the BLOCK RESTART
condition (to coordinate X=50, Y=20, Z=10 in the above example) the movement may be led
back to the 1
st
case.
3 rd case: Interrupting and restarting canned cycle in the course of positioning to point R
If in the sample cycle the movement is interrupted during positioning to point R=2 along axis Z
and it is moved to the start position of the block by means of BLOCK RESTART
condition (to coordinate X=100, Y=70, Z=10 in the above example) the movement may also
be led back to the 1
st
case.
4 th case: Interrupting and restarting canned cycle in the course of hole machining
If the canned cycle is interrupted during hole
machining and it is moved to the start posi-
tion of the block by means of BLOCK RE-
START condition (to coordinate
X=100, Y=70, Z=2 in the above example)
after pressing the START button it re-exe-
cutes the hole machining and retraction.
Return to Block Start Position after Interrupting Machining in Offset mode
The following cases refer to axes in the selected plane, when the offset mode is on. For
interrupting and restarting axis movements outside the selected plane the cases of state G40
can be applied.
