4. AUTOMATIC OPERATION
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.
During movement to the restart position, manual intervention can be used
to perform a return operation for an axis if it has not yet been performed
for the axis. A return operation cannot be done further on axes for which
a return has already been completed.
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.
Regardless of whether machining has started or not, manual operation
must be performed when the manual absolute mode is on.
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.

As a rule, the tool cannot be returned to a correct position under the following conditions.
Special care must be taken in the following cases since none of them cause an alarm:
S Manual operation is performed when the manual absolute mode is OFF.
S Manual operation is performed when the machine is locked.
S When the mirror image is used.
S When manual operation is performed in the course of axis movement for returning operation.
S When the program restart is commanded for a block between the block for skip cutting and
subsequent absolute command block.
