ST600R Autopilot Control Unit
Rudder Limit
Rudder Limit restricts autopilot rudder movement to just less than
the steering systems mechanical stops. This avoids putting the
steering system under unnecessary load.
The range available is as follows:
Range:
15° to 40°
Defaults:
30° Displacement, semi-displacement, planing
20° Sterndrive
Turn Limit
This limits the rate of turn of your vessel when under autopilot
control. The value must be within the range 5 to 20°. For sailboat
applications it should be set to 20°.
Range:
5° to 20° per second
Default:
20° (Displacement)
15° (Semi-displacement)
08° (Sterndrive)
Cruise Speed
The Cruise Speed value is used by the autopilot during Track mode
operation, when it calculates compensation for tidal streams and
leeway.
Set the value to the boat’s normal cruising speed.
Alternatively, set Cruise Speed to Auto mode (A) (not available when
using a Type 100/300 Course Computer) so that Speed Over Ground
(SOG) data is used, if available. SOG will normally give better course-
keeping than a fixed value. However, using SOG could cause
problems at low boat speeds where the tide exceeds 35% of the boat
speed.
Note:
If boat speed data is available via SeaTalk or NMEA, the Cruise
Speed setting is ignored and the actual boat speed is used.
Range:
4 to 60 knots
Defaults:
6 (Displacement)
8 (Semi-displacement)
20 (Planing)
20 (Sterndrive)
