4.AUTOMATIC OPERATION OPERATION B-63324EN-1/03
- 134 -
- During search
Search operation must be performed under the same conditions
including input signal and offset conditions as those used for
machining. Otherwise, return to the correct machining restart position
cannot be made. Note that even when the single-block switch is set to
ON, search operation continues.
- Single block
When single block operation is ON during movement to the restart
position, operation stops every time the tool completes movement
along an axis. When operation is stopped in the single block mode,
MDI intervention cannot be performed.
- Manual intervention
During movement to the restart position, manual operation can be
performed for an axis along which a return operation has not yet been
completed. In this case, return to the restart position can be performed
by the subsequent return operation. When manual operation is
performed for an axis after the tool completes a return operation along
that axis, however, return operation is not performed again along that
axis.
-MDI
After a search is completed, axis movement by MDI cannot be
specified before axes are moved.
- Reset
Never reset during the time from the start of a search at restart until
machining is restarted. Otherwise, restart must be performed again
from the first step.
- Feed hold
When a feed hold has been applied during a search, repeat the restart
operation from the beginning.
- Manual absolute
Regardless of whether machining has started or not, manual operation
must be performed when the manual absolute mode is on.
- Reference position return
If no absolute-position detector (absolute pulse coder) is provided, be
sure
to perform reference position return after turning on the power and
before
performing restart.
- Program restart switch
When the program restart switch is ON, pressing the Cycle Start button
does not start operation.
