9-5-5 Specifying the Operation Direction
The following example illustrates when positioning is performed towards a target position of −20 when
the command current position is 50.
Additional Information
Moves in the same direction as the Current Direction specification if the travel distance is the
same in the positive and negative directions.
The following example illustrates when positioning is performed towards a target position of −20 when
the command current position is 50.
Negative direction Motion starts in the negative direction.
Current direction Motion starts in the same direction as the previous operation.
No direction specified 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.
