RUDDER SENSE (Sensitivity)
Range: 1-10 Default: 1
Theacceptableamountofo󰀨-courseerrorallowedforminorruddercorrections.
Increasing this value reduces the amount of pulses used to keep the
vessel on course.
If the vessels rudder is continuously hunting, always increase this value to avoid
damaging the drive unit.
This value should also be increased in poor weather conditions. For example,
when going up a wave the vessels course may move +6 degrees, on the way
down the vessel corrects itself -6 degrees naturally, therefore Rudder Sense
value should be increased. Otherwise, the SP120C will correct the course
change and drive the rudder on the way up the wave, in turn causing the vessel
to oversteer when moving down the wave, therefore resulting in excessive
unnecessary rudder corrections.
RATE OF TURN
Range: 10-720 (degrees/min) Default: 700
Limits the rudder drive when the SP120C detects the vessel is turning too fast.
I.e. if the rate of change in heading exceeds this value, the SP120C system
limits the rudder drive to limit high speed turns. If this setting is too low, the
vessel may understeer when changing course.
