Follow-up steering
In FU mode you use the lever to set the commanded rudder angle.
Warning: To avoid unintended rudder movement you should
observe the lever position (commanded rudder angle) before
activating the FU mode!
To increase resolution on small rudder angle commands, the
relation between the lever rotation and the commanded rudder
angle is non-linear. When the lever is rotated 20° from mid-position
the rudder will be commanded 5° to port or starboard. A 65° lever
angle will move the rudder to 40°. Max lever rotation will give max
rudder angle. Refer your autopilot installation manual for how to set
max rudder angle.
The rudder will remain in set position until a new rudder angle is
commanded.
AUTO and NoDrift mode
When you select AUTO/NoDrift mode, the system will continue on
the heading/course read from the sensors the very moment you
selected the mode.
Auto mode NoDrift mode
Changing set heading/set course
Use the lever to change set heading in AUTO mode and the set
course in NoDrift mode. The value will change in steps defined by
lever rotation, starting from 0.5°/second at 3° lever rotation, up to
5°/second at max lever rotation.
