The autotuning takes approximately 3 minutes to complete. When
completed the autopilot automatically switches to Standby mode,
and the rudder must be controlled manually.
Ú Note:
All parameters that are set during autotuning can be
manually adjusted. For optimal steering performance it is
recommended to manually adjust the steering parameters after
running the autotune.
Manual tuning
Rudder gain and Counter rudder can be manually adjusted.
• Stabilize the vessel on a heading and set the speed in the middle
of the profile range (well clear of the transition speed) to avoid
profile switching during tuning. Then activate the Rudder gain
option. Adjust the value according to the descriptions below.
If required, adjust slightly the Counter rudder option.
