Display and keypad
This chapter explains how to interpret the display and use the
keypad.
You should refer to the diagrams at the front of this manual for
information on the layout of the display and keypad.
Display
Axis displays
The three Axis displays normally show the positions of the X, Y
and Z axes.
The three Axis Label displays normally show X, Y and Z, (in
Lathe Mode X, Z and Z’).
Function display
While any axis is moving, the Function display shows the
Feedrate of the fastest moving axis. The feed indicator next to
the display is illuminated. The feedrate is displayed in mm/sec
(to a resolution of 0.5) or inches/min (to a resolution of 1.0).
If the lathe indicator is illuminated, then the lathe functions are
available; if the mill indicator is illuminated, then the mill
functions are available; if the lathe and mill indicators are
illuminated, then both the mill and lathe functions are available.
During Setup and Special Functions, the displays may show
information other than that described on this page. See the Set
up and Special functions chapters of this manual for further
information.
Using the keypad
You use the keypad to enter data and control information for the
C80. The keys can have different functions depending on the
operating mode, but in normal operation the keys work as
follows:
Unit Key. Toggles the display units between inches and
millimetres.
Mode Key. Toggles the C80 between Absolute Mode and
Incremental Mode.
Absolute mode
In this mode, the C80 displays the positions of the three axes
relative to a fixed datum.
Incremental mode
In this mode, the C80 displays each position relative to the last
position. This is also known as point-to-point use.
At the beginning of each working session, set the
datum in Absolute Mode, then switch the C80 to
Incremental Mode. By using the C80 in this way, you
can return the machine to its absolute datum at any
time, simply by switching back to Absolute Mode.
