4.1.6
Current target control speed
Equivalent to the target idling speed or the target operating speed. When the M 447 hLAG is used in
buses, no operating speed controllers are required.
4.1.7
Current final limit speed
Final limit speeds are stored in the data record of the MR EGM. The FR can reduce the final limit speed
programmed in the MR with a specification via CAN "Current final limit speed", but CANNOT increase it.
4.1.8
Control-speed target value (FR)
During operation with operating speed control, the "Control-speed target value (FR)" is equivalent to the
operating speed specification for the operating speed controller. During operation outside the operating
speed control, the specification is equivalent to the idling speed. The FR can increase the idling speed
within a certain range, but cannot decrease it.
4.1.9
Redundant speed (Ter. W) (FR)
This is another specification of the engine speed. The FR determines the engine speed from the alternator
speed and makes this information available to the EGM via the CAN.
4.1.10
Engine speed
This is an engine speed determined by the EGM. The EGM determines this based on the
crankshaft/camshaft signal.
