To acquire the amount of fuel consumed, up to 2 fuel meters can be connected.
Assignment to the type of fuel is fixed.
To adapt to different types of fuel meters, assignment of the number of pulses and the
resulting fuel throughput must be parameterized.

17.1.2 Configuration of VSD
The VSD must be configured in accordance with the type of motor connected.
The times set for the acceleration and deceleration ramps must be shorter than the
times of the ramps parameterized for the LMV5x.2... with electronic fuel / air ratio
control.
Example: Ramp of 10 seconds ⇒ VSD ramps to be set to 7 seconds.
The motor must be able to follow the parameterized VSD ramp.
If this is not observed, the predefined speeds will not be reached within the respective
periods of time.
The configuration of the current / voltage interfaces of the VSD must be in accordance
with the configuration of the LMV5x.2... VSD module.
