Motion starts in the negative direction.
Motion starts in the same direction as the previous operation.
Motion starts in the direction that does not pass through the upper and lower limits of
the ring counter. With this direction specification, you can specify a target position that
exceeds the upper or lower limits of the ring counter. If that occurs, relative positioning
is performed using the difference between the target position and the command current
position as the target distance. This enables you to perform multi-turn positioning on
the ring counter.
