General Operation’s Soft Key Functions Detailed
This section details the soft key functions that are the same, whether
the ND 780 is configured for Mill or Turn applications.
Set Zero Soft Key
The SET/ZERO soft key is a key that determines the effect of pressing
an Axis key. This key is a toggle key, switching the functionality
between Set and Zero. The current state is indicated in the Status Bar.
When the state is Set, and the ND 780 is in Actual Value mode,
selecting an Axis key opens the Datum form for the selected axis. If
the ND 780 is in Distance-To-Go mode, a Preset form opens.
When the state is zero, and the ND 780 is in Actual Value mode,
selecting an Axis key sets the datum for that axis to zero at the current
position. If it is in Distance-To-Go mode, the current Distance-To-Go
value is set to zero.
Set/Zero Indicator If the ND 780 is in Actual Value mode and the state of
SET/ZERO is zero, pressing any Axis key resets the current
datum to zero at the current location for that axis.
