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 distance when you specify either absolute or relative travel. Feeding is
not affected by following error. This is achieved by using the latch function of the Servo Drive to deter-
mine 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 wrapping
machines, this enables feeding only on trigger signals for printed marks on films and eliminates other
influences.

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.
For details, refer to the MC_MoveFeed (Interrupt Feeding) instruction in the
NJ-series Motion Control
Instructions Reference Manual
(Cat. No. W508).

Interrupt Feeding
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.

delay in relation to the command position.
