6 Adjusting Autopilot Settings
Rudder limit (rUd StP)
Use the rudder limit screen to set the limits of autopilot rudder control
just inside the mechanical end stops. This will avoid putting the
steering system under unnecessary load. You should adjust this
setting when commissioning the autopilot.
Rudder gain (rUd LEv)
This screen determines the default rudder gain setting. Rudder gain is
a measure of how much helm the autopilot will apply to correct
course errors. The higher the setting the more rudder will be applied.
The default rudder gain is set during the initial seatrial. You can make
temporary changes to this rudder gain value during normal operation.
Counter rudder (rtE LEv)
Counter rudder is the amount of rudder the autopilot applies to try to
prevent the boat from yawing off course. Higher counter rudder
settings result in more rudder being applied. The default rudder gain
is set during the initial seatrial.
Rudder damping (rUd dPG)
Adjust the rudder damping value if the autopilot ‘hunts’ when trying
to position the rudder. Increasing the rudder damping value reduces
hunting.
