- this zone may be defined as a range between + 90 ° and -90 ° about the current zero position of the rudder (ie the home position prior to performing the steering movement).
- a reset zone is defined so that when the angle of rotation or angular position of the rudder is within this zone after a user steering operation, the rudder is zeroed by the constant velocity electric motor, preferably 18 revolutions per minute Position of the rudder or is reset to a position in the non-return zone; this zone is preferably defined as the area between the ends of the non-return zone and 90% of the maximum possible number of clockwise and counter-clockwise rudder revolutions, the maximum possible number of rudder line revolutions being preferably determined at engine start-up.
- the reset function can be deactivated in the engine control, in which case the behavior of the steering unit corresponds to the behavior at an angle of rotation within the non-return zone.
- the ranges between 90% and 100% of the maximum possible number of clockwise and counterclockwise rudder revolutions are defined as border zones or areas in which the electric motor is operated in such a way that the rudder is not or only with considerable forces ( these forces are higher than the forces required to move the rudder when its angular position is within the Resetting zone is located) can be moved in the direction of the steering movement, which are preferably higher, the more the revolutions of the rudder approach the maximum possible number of rudder revolutions, being provided in the context of an advantageous development of the invention that the rudder by the electric motor with constant speed to a defined position within the reset zone, eg 90% of the maximum possible number of rudder turns or to a position within the non-return zone.

- the current in the ranges between 90% and 100% of the maximum possible number of clockwise and counterclockwise rudder revolutions is constant and has a maximum value, for example 7.2 A.
- the definition of the zones can be varied so that e.g. the boundary zone begins at Y% of the maximum possible number of clockwise and counterclockwise rudder revolutions, where Y can take a value between 45 and 95; also, the non-return zone can be defined as a range between + X ° and -X ° around the current zero position of the rudder, where X can take values in the interval between 1 ° and 135 °.
- the mechanical resistance at the rudder (ie the current with which the motor is operated) generated by the electric motor upon actuation of the rudder by the user is a function of the speed in the reset zone and in the non-return zone, wherein the resistance preferably increases linearly with increasing speed up to a predetermined limit value, wherein in the limit zone, as already explained, the resistance either has a constant maximum value or in the absence of the still missing revolutions up to the maximum possible number of rudder revolutions up to the maximum malty value rises.
- the mechanical resistance at the rudder created by the electric motor upon actuation of the rudder is a function of speed, with the resistance preferably increasing linearly with increasing speed up to a predetermined limit increases.
- a speed is defined below which the current at the electric motor is zero, so that no mechanical resistance is generated during a movement of the rudder, above which speed the current increases and a mechanical resistance is generated.

- the electric motor is switched on and the rotor is not moved, with the current position of the incremental encoder being defined as the zero position, which corresponds to the absolute zero position, preferably the straight-ahead position (steps A, B).
- step C If the torque acting on the rotor is greater than the friction torque and the moment of inertia of the rotor (step C), it is determined whether the rotational movement caused thereby is clockwise or counterclockwise, wherein the motor is controlled so that it receives a torque against generates the rotational movement caused by the steering movement (step D).
