Rudder limit
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 (see page 61).
Rudder gain
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:
• Type 150G/400G autopilots will adjust the rudder gain
automatically during the AutoLearn (see page 68)
• Type 150/400 and Type 100/300 autopilots will require manual
adjustment of rudder gain (see page 71)
You can make temporary changes to this rudder gain value during
normal operation (see page 29).
Counter rudder
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:
• Type 150G/400G autopilots will adjust the counter rudder setting
automatically during the AutoLearn (see page 68)
• Type 150/400 and Type 100/300 autopilots will require manual
adjustment of counter rudder (see page 71)
