Power follower “power follower”
Activates the power follower function.
P1.6.2.10

Power limit follower hysteresis “PowerFoll.Hyst”
Defines the hysteresis of the actual power where the internal power limit is kept while
the input power limit is higher than the actual power.

Scaling of motoring power limit “MotPowerLimSclng”
The motoring power limit is equal to parameter Motoring Power Limit if value ‘Not
Used’ is selected. If any of the inputs is selected the motoring power limit is scaled
between zero and parameter P1.6.2.3 Motoring Power Lim.
0 = Parameter
1 = AI1
2 = AI2
3 = AI3
4 = AI4
5 = Fieldbus Scaling ID46 (Monitoring Value)
P1.6.2.12
1088
Scaling of Generating power limit “GenPowerLimSclng”
The generator power limit is equal to parameter Generator Power Limit if value ‘Not
Used’ is selected. If any of the inputs is selected the generator power limit is scaled
between zero and parameter P1.6.2.2 Generator Power Lim.
0 = Parameter
1 = AI1
2 = AI2
3 = AI3
4 = AI4
5 = FieldBus Scaling ID46 (Monitoring Value)
P1.6.2.13
1611
Under voltage power limit DC level “UV Power C Levl”
This parameter defines the DC voltage level when the special power limit function is
activated. When DC voltage goes below this level the power level defined by under
voltage power limit will be activated.
5.6.2.1 Power follower function
The power follower function will keep the internal power
limit near the actual power so that when power demand
increases the increase rate is controlled by the power limit
increase rate parameter. This function makes the power
increase smoother for the ship generator when e.g. speed
reference is increased or when propeller gets air and comes
back to the water.
