Parameters List:
1. Pulse Drive Time
The minimum pulse width when
the autopilot is in NO RFU mode.
When the system is near to the
desired position, the pulse of
current applied to the motor will
have this length. This parameter
is not used when in RFU mode.
This parameter may be
necessary to be increased if the
rudder is not moving and the
course error of the boat is bigger
than the dead band. It depends
on the power of the system which
moves the rudder and the inertia
of the rudder. The pulse must be
long enough for start moving the
rudder.
