- 501 -
Restart of automatic operation with the block return switch turned on
If the cycle start button is pressed while the block return switch is on,
the tool length compensation value and the cutter compensation value
are recalculated, and automatic operation is restarted toward the
compensated end point from the current position.
Fig. 5.8 (b)
The tool moves toward the recalculated end point from its current
position regardless of whether it has been returned to the start point of
or an arbitrary point in the interrupted block prior to pushing the cycle
start button.
- Block restart interference check
The block restart interference check is made based on the value (d:
permissible block restart interference check value) set in parameter No.
7651. The interference check issues an alarm unless the distance
between the normal path and the block restart point is within d.
Fig. 5.8 (c)
The block restart interference check function can be enabled and
disabled using bit 7 of parameter No. 7605. However, the interference
check is not performed in the following cases even if it has been
enabled:
The tool is retracted to this
position so the tool can be
replaced.
