Separate Value/Sum Display (ND 970 only)
Separate value display
In this mode the positions of the saddle and top slide are displayed
separately. The position displays are referenced to the datum points
that you set for the Zo and Z axes. When an axis slide moves, only the
position display for that axis changes.
Sum display
In this mode the position values of both axis slides are added together.
The sum display shows the absolute position of the tool, referenced to
the workpiece datum.
Example Separate value display: Z = +25.000 mm
(see illustra-) Zo = +15.000 mm
tion at right) Sum display: Z
S
= +40.000 mm
The sum display will only show correct values if the actual
position values of both axis slides were correctly added and
entered (with sign) when setting the datum for the “sum.”
To switch over the display:
➤ Press S z
When the ND 970 displays sums, the Zo display is switched
off.
