Recall Autotuned - Simrad AP26 Manual

Simrad AP26 and AP27 Autopilots
Counter Rudder is the parameter that counteracts the effect of
the boats turn rate and inertia. For a short time period it is
superimposed on the proportional rudder response as provided
by the heading error. It may sometimes appear as if it tends to
make the rudder move to the wrong side (counter rudder).
The best way of checking the value of the Counter Rudder
setting is when making turns. The figures illustrate the effects off
various Counter Rudder settings.
Autotrim standard value is 40 sec. which should work well on
most boats.
