Detail program description - Servo adjustment
frame.
Notice:
It may be necessary to fi rst assign a control to a servo
attached to one of the 5 ... 12 control channels. If
necessary, this is to be done in the "Control adjust"
menu, see page 96 or 100.
To create an asymmetric travel path, the respective
control (joystick, proportional rotary control or switch) is
to be moved to the side to be set such that it covers only
the marked frame.
The value setting is activated by briefl y pressing the
center
SET button in the right touch pad. The value
fi eld will be displayed in inverse video. Values can be
changed with the arrow keys of the right touch pad.
Pressing the center
SET
button in the right touch pad
will complete the entry.
Simultaneously pressing the cd or ef keys in
the right touch pad (CLEAR) will reset the changed
parameter in the entry fi eld back to 100 %.
Important:
In contrast to settings made with the "Control adjust"
menu, all settings made in this menu affect exclusively
the respective servo, independent of how the control
signal for this servo is produced, i.e. directly by a control
stick or by way of any mixer functions.
The adjacent fi gure
shows and example of
a side-dependent servo
setting, -50 % and
+150 %.

Column 5 "limit"
The "- lim +" column is reached by pushing the marked
frame with the f arrow key of the left or right touch pad,
analogous to the pointers at the bottom of the screen, to
the right beyond the "- trv +" column.

To create a symmetric, i. e. control-side independent
limit, the respective control (joystick, proportional rotary
control or switch) is to be put into the position in which
the marked frame covers both sides of the travel setting.
To set asymmetric travel, the respective control (joystick,
proportional rotary control or switch) is to be moved to
the side on which the marked frame only includes the
value to be changed.
Simultaneously pressing the cd or ef keys in
the right touch pad (CLEAR) will reset the entry fi eld
displayed in inverse video back to its "0 %" value.
Example:
A servo is controlled separately by two controls over a
mixer and but, for model-specifi c reasons, must only be
operated over a servo travel path of 100 % because, for
example, the rudder would mechanically collide with the
elevator if moved more than 100 %.
As long as only one control is used at a time, this is
no problem. But this does become a problem when
the signals of both controls (e. g. aileron and rudder)
combine to form an overall travel in excess of 100 %.
The linkage and servos could be strained excessively …
To prevent this, the travel should certainly be limited by
way of an individual travel limit. In the case of the rudder
used in the example, this would be a value slightly less
than 100 % – because it is assumed the rudder would
collide at 100 % – .
