HEIDENHAIN ND 760 E - Manual (Page 17)

MIN position display in the EDM axis:
Since the EDM axis moves up and down very rapidly during
the EDM process, it is difficult to read the attained erosion
depth from the position display. The ND 760 E therefore
allows you to select an operating mode which displays the
last position value in the EDM axis.
Sequence of keys:
Call the MIN position display.
Exit the MIN position display mode.

In this operating mode, you cannot set any datums.
The MIN position display is active if the leftmost decimal
points light in all axes. The MIN position is internally updated
every 5 ms. However, the display is updated only approx.
every 30 ms in the MIN position display mode.
In this operating mode, the two other axes indicate the final
erosion depth and the distance-to-go (with respect to the
final erosion depth).
