64 8025/8030 CNC OPERATING MANUAL
3.10.2. Zooming (windowing)
The CNC has a ZOOM function by which entire graphics or parts of them can be enlarged
or reduced by this feature. To use this ZOOM function the program must be either
interrupted or completed.
Press the key which corresponds to the view in which the zooming is desired. Then press
[ZOOM] and a rectangle identifying the window will be displayed over the existing
graphic.
Its dimensions can be altered pressing or on the front panel and its position
by using cursor moving keys.
The coordinate values of the window’s center and the width and the percentage are
displayed on the CRT. The display of values can be useful to check the coordinate values
of a particular point (by placing the center of the window over it) and also to measure
distances between two points.
If [EXECUTE] is pressed, the windowed area will fill the CRT.
Using the FEEDRATE override knob, the graphic drawing speed can be altered.
To repeat the whole ZOOM sequence, start by pressing [ZOOM] as before.
To exit the ZOOM mode and continue, press [END].
3.10.3. Redefinition of the display area by the ZOOM function
With the ZOOM function active after pressing [ZOOM], if ENTER is pressed
[EXECUTE] the position and width of the rectangle override the previous values given
to the display area when it has been defined.
The position and the size of the graphic can thus be altered.
Atention:
It is recommended that a sufficiently large width be assigned to the
display area the first time it is defined to guarantee that the complete
graphic will be displayed on the screen and then ZOOM in to center it and
enlarge it.
When the ZOOM function is used, it is necessary to bear in mind that the
CNC will keep information on approximately the last 500 blocks with
movement which have been executed, therefore, if the programme has
more blocks with movement, only those retained will appear in the new
diagram.
