3.1 POSITION Screens
There can be five types of POSITION screens. The first four screens displays the selected
position with big-size characters, meanwhile on the fifth screen all position displays as well as
in case of six or fewer axes the feed and revolution values are also displayed with normal
characters. In case of an oriented spindle when the loop is closed (state M19) the screen shows
the angle position of the spindle instead of the revolution. If the spindle can be programmed as
axis C, the line starts with C in place of S. In the line of feed display the current coordinate
system number can also be read.
ABSOLUTE POSITION Scre-
en (Absolt): In the
selected coordinate
system in respect of the
appropriate offsets and
compensations.
RELATIVE POSITION Scre-
en (Relatv): After refer-
ence point has been re-
turned it corresponds to
absolute position. It can
be overwritten or zeroed
in an optional state.
MACHINE POSITION Scre-
en (Mach): Position measured
in the G53 coordinate system in respect of length offsets.
END POSITION Screen: End
position of the block in
the current coordinate
system in respect of
length offsets.
OVERALL POSITION Screen
(Overll): Beside the
previous four displays
the distance to go also
gets to be displayed. It
shows how much is left
of the current movement.
By this display (in case of
six or fewer axes) the
programmed and current
feed and revolution can
also be seen.
