9 OPERATION FOR MOTION SFC AND PARAMETER
(3) NMI task operation
[Operations]
The Motion SFC program is executed when the input set to the NMI task factor
among external interrupts (16 points of QI60) turns on.
• Number of consecutive transitions is set to "2".
Sequence program
External interrupts
NMI task
END operation: End
END operation: Continue
Do not execute a
program before the
NMI task starting.
(Note) : When making it
always execute,
set as automatic
start.
[Points]
(a) NMI task has the highest priority among the normal, event and NMI tasks.
(b) If the event task is disabled (DI) by the normal task, the interruption of the
NMI task is executed, without being masked.
(c) When parallel branching during NMI task execution, the additional route from
the branch starts execution from the next interrupt occurrence.
[Errors]
The motion control step is executed during NMI task.
If the motion control step is executed during NMI task, the Motion SFC error
(error code: 16113) occurs and stops the Motion SFC program.
