Drive type
This indicates the type of drive installed. The display will show
“Motor”, “Solenoid”, “Proportional” or “Analog”, respectively.
The reading is obtained from the Automatic rudder test under
the Dockside menu. The set value may be changed here.
Drive out
Not applicable for “Analog” drives.
Shows the amount of power needed to achieve the correct
rudder speed. The reading is obtained from the Automatic
rudder test under the Dockside menu. The set value may be
increased or decreased here.
Prop. gain
Applicable only for “Proportional” drive.
This parameter is set automatically when the Rudder Test is
done in the Dockside menu. It influences the start/stop slope of
the rudder. The value could be increased if rudder response to a
start/stop command feels too slow. The value could be
decreased if start/stop feels too quick and causes rudder angle
overshoot when stopping.
Range: 1-25
Default: 18, updated during Rudder Test.

Rudder
Rudder sets the rudder gain, which is the ratio between the
commanded angle and the heading error. Default value depends
on boat length.
Range: 0.05 to 4.00.
