7.2.2
External Positioning (EX_POSING)
The EX_POSING command positions the axis to the target position using the specified target posi-
tion and speed. Parameters related to acceleration and deceleration are set in advance.
If the external positioning signal turns ON during axis movement, the axis will move the distance
specified for the External Positioning Move Distance from the point at which the external positioning
signal turned ON, and then stop. If the external positioning signal does not turn ON, positioning will
be completed to the original target position.
