11. SETTING AND DISPLAYING DATA
635
The current position of the tool in the relative coordinate system can be
reset to 0 or preset to a specified value as follows:
Procedure to set the axis coordinate to a specified value
1 Enter an axis address (such as X or Z) on the screen for the relative
coordinates. The indication for the specified axis blinks and the soft
keys change as shown on the left.
2 D To reset the coordinate to 0, press soft key
[ORIGIN]. The relative
coordinate for the blinking axis is reset to 0.
D To preset the coordinate to a specified value, enter the value and
press soft key
[PRESET]. The relative coordinate for the blinking
axis is set to the entered value.
Procedure to reset all axes
1 Press soft key [(OPRT)].
2 Press soft key
[ORIGIN].
3 Press soft key
[ALLEXE].
The relative coordinates for all axes are reset to 0.
Bits 4 (DRL) and 5 (DRC) of parameter 3104 can be used to select
whether the displayed values include tool offset and tool nose radius
compensation.
Bit 3 of parameter 3104 is used to specify whether the displayed positions
in the relative coordinate system are preset to the same values as in the
workpiece coordinate system when a coordinate system is set by a G50
(G code system A) or a G92 (G code system B or C) command or when
the manual reference position return is made.
On the 9 CRT or the shared screen of the 14 CRT, only the coordinates
for the first to fifth axes are displayed initially whenever there are six or
more controlled axes. Pressing the
[REL] soft key displays the
coordinates for the sixth and subsequent axes. When six or more
controlled axes are used under two–path control, the coordinates for
path 1 are displayed initially on the 9 CRT. Pressing the
[REL] soft key
displays the coordinates for path 2. On the shared screen of the 14 CRT,
the tool post selection signal is used to select the display for path 1 or 2.
