7.6.2.1 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.
P2.6.2.9 Power Follower ID1705
Activates the power follower function.
P2.6.2.10 Power limit follower hysteresis ID1529
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.

P2.6.2.11 Scaling of Motoring Power Limit ID179
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 P2.6.2.3 Motoring Power Lim.
