Skip Function in which Disregards Stop Command

When the current positioning is stopped by input from external source and the next positioning control is performed, it enables
starting of the next positioning control even if the input from external source is on (continuation).
There are following tow functions in the function called "Skip".
• Skip during CP command (Page 360 Pass point skip function)
• Skip in which disregards stop command
Usually, although an error [***] occurs with the servo program start during the STOP signal on, if "[Rq.1149] External stop
input disable at start command (R: M34489+32n/Q: M3209+20n)" turns on and the servo program starts, the next servo
program starts even if during the STOP signal on.
Skip function procedure
The procedure for the skip function by the external STOP signal and Motion SFC program is shown below.
Start
Positioning start using the
servo program
Turn on the external STOP
signal at the positioning stop
Turn on the "[Rq.1149] External
stop input disable at start
command (R: M34489+32n/
Q: M3209+20n)"
Start the positioning using the
next servo program after
deceleration stop
End
Operation timing
The operation timing for the skip function is shown below.
[Rq.1120] PLC ready flag
(R: M30000/Q: M2000)
[Rq.1123] All axes servo ON
command
(R: M30042/Q: M2042)
Servo program start
External STOP signal
[Rq.1149] External stop input
disable at start
(R: M34489+32n/Q: M3209+20n)

Positioning does not start if the STOP signal,
"[Rq.1140] Stop command (R: M34480+32n/Q: M3200+20n)" or
"[Rq.1141] Rapid stop command (R: M34481+32n/Q: M3201+20n)"
turns on.
. . . . . . .
Turn "[Rq.1149] External stop input disable at
start command (R: M34489+32n/Q: M3209+20n)" on to use the
skip function.
(The external STOP signal becomes invalid at
the next positioning start.)
If "[Rq.1149] External stop input disable at
start command (R: M34489+32n/Q: M3209+20n)" turns off,
the external STOP signal becomes valid,
and if the STOP signal is input,
the positioning does not start.
. . . . . . .
Confirm the operation stop with the
"[St.1040] start accept flag (R: M30080+n/Q: M2001+n)"
turns off.
