9-1-4 Interrupt Feeding
Interrupt feeding feeds the axis at the specified velocity and for the specified distance from the actual
position when a trigger signal occurs.
You can also select to output an error if the trigger signal does not occur within the specified travel dis-
tance when you specify either absolute or relative positioning.
Feeding is not affected by following error. This is achieved by using the latch function of the Servo Drive
to determine the actual position when the trigger signal occurs. You can also use the window function to
disable trigger signals that occur outside of a specified position range. For applications such as wrap-
ping machines, this enables feeding only on trigger signals for printed marks on films and eliminates
other influences.
 Feeding for a Specified Distance in the Moving Direction
 Feeding for a Specified Distance in the Direction Opposite to the Moving
Direction
If decelerating to a stop after a reverse turn is specified for the Operation Selection at Reversing axis
parameter, an acceleration/deceleration curve is used when reversing.
9-1-4 Interrupt Feeding
Motion Relative to the Actual Position
When the interrupt input occurs, the specified travel distance is
added to the actual position and used as the target position for
the command position.

The figure on the left shows that there is a follow
delay in relation to the command position.
