15.3.2 Description of Operation

Operation to disable stopping of single block operations
Single block operation can be specified per part system, which enables cycle operation of other part systems to be suspended
by stopping single block operation for one part system and enables cycle operation of other part systems to be suspended by
stopping single block operation for any part system.
Part system 1
(Single block operation
ON)
Part system 2
(Single block operation
ON)
Part system 3
(Single block operation
OFF)
For the following scenario, the stopping of single block operation is disabled and so single block operation does not stop.
 During cycle operation such as a fixed cycle.
The block that operates in single block mode differs depending on the particular cycle.
Refer to the cycle section in the "Programming Manual".
 During tapping mode.
 During single block stop control by system variable #3003/bit0.
Operation of the cycle operation suspension disabled state
When a part system other than the part system for which single block operation is attempting to be stopped is in the cycle
operation suspension disabled state (tapping, thread cutting, or cycle operation suspension disabled by system variable
#3004/bit0), the corresponding single block continues to operate uninterrupted, and the cycle operation of other part systems
is also not suspended. For the next scenario in which any part system is attempting to stop single block operation, if a part
system other than the part system attempting to stop single block operation is in the cycle operation suspension enabled
state, single block operation stops, and the cycle operation of other part systems is also suspended.
Part system 1
Operation automatic operation
pause is not possible
Part system 1
(Single block operation
ON)
Part system 2
(Single block operation
ON)
Part system 3
(Single block operation
OFF)
In this case, the system enters the cycle operation suspension disabled state and so cycle operation is not suspended.
 Cutting feed is in operation during a fixed tapping cycle.
 During tapping mode.
 During thread cutting.
 Cycle operation suspension control is in operation by the system variable #3004/bit0.
