List
• When just before is the motion control step, transits to the next
step by formation of transition condition Gn (G0 to G4095)
without waiting for the motion operating completion.
• When just before is the operation control step, transits to the
next step by the completion of transition condition after
operating execution.
• When just before is subroutine call or starting step, transits to
the next step by formation of transition condition without waiting
for the operating completion of subroutine.
• When just before is the motion control step, waits for the motion
operating completion and then transits to the next step by the
completion of transition condition Gn (G0 to G4095).
• When just before is the operation control step, transits to the
next step by formation of transition condition after operating
execution. (Same operation as Shift.)
• When just before is subroutine call or starting step, waits for the
operating completion of subroutine and then transits to the next
step by the completion of transition condition.
• Prepares for starting of the next motion control step, and issues
an instruction immediately when the specified bit device turns
ON.
• Always pair this transition with the motion control step one-for-
one.
• Prepares for starting of the next motion control step, and issues
an instruction immediately when the specified bit device turns
OFF.
• Always pair this transition with the motion control step one-for-
one.
• When just before is the motion control step, transits to the next
step by formation of transition condition Gn (G0 to G4095)
without waiting for the motion operating completion. If not
formation of transition condition, transits to the right-connected
step.
: • When just before is the operation control step, transits to the
next step by the completion of transition condition after
operating execution. If not the completion of transition
condition, transits to the right-connected step.
: • When just before is "subroutine call" or "starting step", transits
to the next step by the completion of transition condition
without waiting for the operating of subroutine completion. If not
formation of transition condition, transits to the right-connected
step.
