Rudder Sensitivity / Ratio
These settings are used to determine how sensitive the autopilot system
is and the amount of rudder the vessel requires for steering (actually, the
amount of rudder angle applied for a given angle off-course).
To adjust, press the MODE button. The display will show “S **” and
the present sensitivity setting will be displayed (between 1 and 10).
•
The sensitivity setting may be altered by the
<

buttons.
With a low response value the drive will operate with
minimum pulsing to the required rudder position and the
autopilot system may work continuously.
•
A high response value the drive will position the rudder with
maximum pulsing.
NOTE:
Too low a setting may cause the steering motor to
work continuously (hunting). The response setting should be
increased from 1 until the rudder position is achieved with 1 or 2
motor pulses.
By pressing the MODE button a second time, the display will indicate
“r **”. This setting is used for adjusting the autopilot’s rudder ratio
setting to allow for varying vessel size and speed.
The display shall change to show “r **” and display shall show the
current rudder ratio (between 1 and 10).
The rudder setting may be altered by the
