4. AUTOMATIC OPERATION
Regardless of whether processing has started, manual absolute mode
must be set when manual operation is performed.
If no absolute–position detector (absolute pulse coder) is provided, before
restart, always perform reference position return after turning on the
During search operation, neither a dwell command nor laser output
command is executed.
(1)The program executed just before can be restarted.
(2)The program executed before the power was turned off cannot be
restarted when the power is turned on again.
(3)For programs that are to be restarted, it is impossible to change a work
(4)Move commands (G27, G28, G29, G30, and G53) that use the
machine coordinate system are ignored during program restart.
(5)No program can be restarted from a midpoint of a spatial arc
interpolation (G12) command.
(6)A program cannot be restarted from a block in a subprogram.
(7)All manual operations must be performed with “manual absolute”
turned on no matter whether machining has not been started or has
(8)Neither the dwell command nor the laser output command is executed
during a search.

The specified block number for restarting the program is not
After interruption, a coordinate system was set, then P–type
restart was specified.
After interruption, the coordinate system shift was changed,
then P–type restart was specified.
After interruption, the coordinate system was changed, then
P–type restart was specified.
When automatic operation has not been performed since
the power was turned on, an emergency stop was re-
leased, or alarm 094 to 097 was reset, P–type restart was
After the power was turned on, a restart operation was per-
