9.12 Travel-dependent working with the digital slope sensor
This is not an additional sensor in the actual meaning of the word
The digital slope sensor already described above is used to register the
actual value of the tool slope. In contrast to the digital slope sensor, in
travel-dependent working with the digital slope sensor the nominal
value is not entered manually but defined automatically by the system
according to the covered distance.
The user cannot adjust the nominal value in the automatic mode.
Function:
In addition to the normal lateral slope control (see "9.1 Working with the
digital slope sensor"), travel-dependent controlling is also possible with
the digital slope sensor. In this case, a required lateral slope is adjusted
according to the covered distance. The following section refers to this
kind of control as "delta slope control".
If the delta slope sensor is selected during on-going slope control, the
slope control operating hitherto continues in auto mode.
After making the selection, the system asks first for the target slope and
then for the distance. The target slope is the slope value to be achieved
at the end of the entered distance. Delta slope control can begin once
these two values have been entered.
On starting the function, the delta value is formed once between the
current slope and the target slope. This value now undergoes linear
interpolation to the distance.
At the end of the distance, delta slope control finishes automatically and
the system changes over to normal slope control, i.e. the target slope is
now kept constant.
