▪ Hard limitation by injection cut off and/or ignition cutoff of all cylinders
To achieve a good dynamic behavior by advanced intervention, the engine speed
is predicted by means of the speed gradient.

Codeword for type of intervention dur‐
ing soft limiter:
0 = only ignition retard
1 = injection cutoff
2 = ignition cutoff,
3 = injection and ignition cutoff
Codeword for type of intervention dur‐
ing hard limiter:
1 = injection cutoff
2 = ignition cutoff,
3 = injection and ignition cutoff
Engine speed limit, gear dependent
Determines the slope of the soft limiter
between soft limit and hard limit.
Predefined. Vary according to your en‐
gine´s dynamic behavior.
Prediction time for rev limiter, depends
on the inertial torque of the engine. If
oscillations occur, reduce value or turn
off by setting = 0.0.
