3.2 POSITIONING
This command moves a tool to the position in the workpiece
coordinate system specified with an absolute or an incremental
command at a rapid traverse rate.
In the absolute command, coordinate value of the end point is
programmed.
In the incremental command the distance the tool moves is
programmed.
Either of the following tool paths can be selected according to
parameter.
• Nonlinear interpolation type positioning
The tool is positioned with the rapid traverse rate for each axis
separately. The tool path is normally straight.
• Linear interpolation type positioning.
The tool is positioned within the shortest possible time at a speed
that is not more than the rapid traverse rate for each axis.
End point
Nonlinear interpolation type positioning
Start point
Linear interpolation type positioning
In the positioning mode based on G00, the machine is accelerated up
to a specified feedrate at the start of a block. At the end of the block,
the machine is decelerated to a stop to make an in-position check (to
see if the machine has arrived at a specified position).
By parameter setting, an in-position check for each block can be
disabled.

IP_ : For an absolute command, the coordinates of an end
point, and for an incremental command, the distance
the tool moves.
