4.1 POSITIONING (G00)
The G00 command moves a tool to the position in the workpiece system
specified with an absolute or an incremental command at a rapid traverse
In the absolute command, coordinate value of the end point is
In the incremental command the distance the tool moves is programmed.
Either of the following tool paths can be selected according to bit 1 of
parameter LRP No. 1401.
- Nonlinear interpolation positioning
The tool is positioned with the rapid traverse rate for each axis
separately. The tool path is normally straight.
- Linear interpolation positioning
The tool path is the same as in linear interpolation (G01). The tool is
positioned within the shortest possible time at a speed that is not more
than the rapid traverse rate for each axis.
Fig.4.1 (a) Tool path
The rapid traverse rate in G00 command is set to the parameter No. 1420
for each axis independently by the machine tool builder. In the
posiitoning mode actuated by G00, the tool is accelerated to a
predetermined speed at the start of a block and is decelerated at the end
of a block. Execution proceeds to the next block after confirming the
"In-position " means that the feed motor is within the specified range.

position, and for an incremental commnad, the
