- Overview of operation
• In the case of positioning of non-linear interpolation type (bit
1 (LRP) of parameter No. 1401 = 0)
As shown below, single direction positioning is performed
independently along each axis.

• In the case of positioning of linear interpolation type (bit 1
(LRP) of parameter No. 1401 = 1)
Positioning of interpolation type is performed until the tool once
stops before or after a specified end point. Then, the tool is
positioned independently along each axis until the end point is
reached.

Limitation
• Single direction positioning is not performed along an axis for
which no overrun distance is set in parameter No. 5440.
• Single direction positioning is not performed along an axis for
which travel distance 0 is specified.
• The mirror image function is not applied in a parameter-set
direction. Even in the mirror image mode, the direction of single
direction positioning remains unchanged. If positioning of linear
interpolation type is used, and the state of mirror image when a
single direction positioning block is looked ahead differs from
the state of mirror image when the execution of the block is
started, an alarm is issued. When switching mirror image in the
middle of a program, disable looking ahead by specifying a
