Response
The Autotune function in the AP26 and AP27 is so refined that
80-85 % of the boats will need no further adjustments of the
steering parameters. On some boats, however, or at particular sea
conditions a fine tuning of the steering parameters may improve
the performance of the autopilot.
The Response control allows you to make this fine
tuning. It can be set to seven levels. Level 3 (default)
has the values of Rudder and Counter Rudder
parameters set by the Autotune function. If no
Autotune is made (not recommended) the level 3
values are the factory default values.
A low response level reduces the rudder activity and provides a
more “loose” steering.
A high response level increases the rudder activity and provides
a more “tight” steering.
A too high response level will make the boat start S-ing.
Range: 1 – 7
Default: 3
NAV Mode
The User setup for NAV mode is identical to the User setup for
AUTO mode.
WIND Mode
The User setup for WIND mode includes the same
items as the User setup for AUTO mode. In addition
you have:
Wind response
If the difference between the set wind angle and the actual wind
angle is too big, the ‘Wind response’ can be increased to reduce
the deviation.
Note ! First make sure that the course keeping is acceptable, i.e. the
difference between the Course To Steer (CTS) and the actual
heading is at a minimum.
