(1) Stops the specified Motion SFC program running.
(2) The clear-specified Motion SFC program will not start automatically after stopped
if it has been set to start automatically.
(3) The specified program may be its self program.
(4) If the specified program is being subroutine called, the subroutine program called
is also stopped. (Shown below)
MAIN
SUB

WAIT
END
END
(5) When the specified program has been subroutine started, the subroutine program
started continues processing. (Shown below)
MAIN SUB
SUB
Shift
END
END
(6) When the servo program started from the specified program is starting, the servo
program continues processing.
(7) The servo program is executed after waiting completion of condition in
"WAITON/WAITOFF + motion control step". Input the stop command of target axis
in addition not to execute the servo program.

error (error code: 16203) will occur.
Symbol
Stops the Motion SFC program of the specified
program name.
If the program has been "subroutine called" as shown on the left
When the call source program (MAIN) is cleared.
Even if the subroutine (SUB) is running, both the call source
program (MAIN) and subroutine (SUB) stop running.
When the subroutine (SUB) is running, the subroutine (SUB)
stops running and execution to the call source program (MAIN).
If the program has been "subroutine started" as shown on the left
When the started program (MAIN) is cleared.
Even if the subroutine (SUB) is running, the started program
(MAIN) stops running but the started subroutine (SUB)
continues processing.
When the subroutine (SUB) is cleared
If the subroutine (SUB) is running, only the subroutine (SUB)
stops running.
