3.5.2 DRAW Screen
In the drawing area in the middle
of screen the current tool center is
shown by a cross. The following
information can be read in the top
right corner of the screen: Current
feed, spindle revolution and the
number of the current tool. Fur-
ther on in the column the position
display of axes can be seen as se-
lected on the POSITION DIS-
PLAYS screen. (see the chapter
3.1 on the page 22 ). In the bottom
right corner the scale, below it the
diagram symbolizing the position
of the coordinate system are
shown.
In case of automatic execution the cross indicates the current tool position. A dot is also put to
the center of the cross. The drawing depends on the speed of movement; as the points are
drawn only a few times per second, in case of fast movement the drawn tool path will be not a
continuous line, but a dotted one.
L Note: the size of the cross is defined by parameter 0561 CROSS DOT. The value entered
at the parameter specifies the length of the leg of the cross in raster. The value cannot
be greater than 7.
