• Counter rudder: Relation between change in heading error and
applied rudder. Higher counter rudder will reduce applied rudder
faster when approaching the set heading
• Auto trim: Controls how aggressively the autopilot will apply
rudder to compensate for a constant heading offset, e.g. when
external forces such as wind or current affects the heading.
Lower auto trim will give faster elimination of a constant heading
offset
Ú Note:
In VRF mode this parameter controls the time constant of
the rudder estimate. A lower value makes the rudder estimate
faster, i.e. that it will more quickly catch up with the boat's
movements.
• Init rudder: Defines how the system moves the rudder when
switching from manual steering to an automatic mode.
- Center: Moves the rudder to zero position
- Actual: Maintains the rudder offset
• Rudder limit: Determines the maximum rudder movement in
degrees from midship position that the autopilot can command
the rudder in the automatic modes. The Rudder limit setting is
only active during autosteering on straight courses, NOT during
course changes. Rudder limit does not affect Non-Follow-up
steering
• Off heading limit: Sets the limit for the off heading alarm. An
alarm occurs when the actual heading deviates from the set
heading more than the selected limit
• Track response: Defines how fast the autopilot shall respond after
having registered a cross track distance
• Track approach angle: Defines the angle used when the vessel is
approaching a leg. This setting is used both when you start
navigating and when you use track offset
• Course change confirm angle: Defines the limits for course
change to next waypoint in a route. If the course change is more
than this set limit, you are prompted to verify that the upcoming
course change is acceptable.
