Note ! The values in the table are factory set (default) and listed for
information only. After having performed the Automatic tuning,
the values may differ from those listed in the table. See also
“Automatic Tuning” previously in this chapter.
The two most important parameters that determine the
performance of the automatic steering are Rudder and Counter
Rudder.
Rudder
sets the rudder gain which is the ratio between the
commanded angle and the heading error.
• Too little Rudder and the autopilot fails to keep a steady
course.
• Too much Rudder gives unstable steering and reduces speed.
