4.2 Setup Procedure
4.2.4 Setting the Moving Method of the Rotational Coordinate System
Example of Absolute Positioning Operation
Positioning is performed by moving the axis from the current position to the target position.
The following figure gives an example of a positioning operation in which the axis is moved for-
ward from the current position to target position 1 and then moved in reverse to target position 2.

Example of Reverse Positioning Operation
Positioning is performed by moving the axis in reverse from the current position to the target position.
The following figure gives an example of a positioning operation in which the axis is moved in
reverse from the current position to target position 1 and then to target position 2.

Pn87C
Example of Forward Positioning Operation
Positioning is performed by moving the axis forward from the current position to the target position.
The following figure gives an example of a positioning operation in which the axis is moved for-
ward from the current position to target position 1 and then to target position 2.

Current position
Example of Near Course Positioning Operation
Positioning is performed by moving the axis in the direction in which the distance from the cur-
rent position to the target position is shorter.
If the distance from the current position to the target position is the same in both the forward
and reverse directions, positioning is performed by moving in the forward direction.
The following figure gives an example of a positioning operation in which the axis is moved in
reverse a short distance from the current position to the target position.
