9.8 Description of the throttle regulation
ACE0/CombiAC0 controls the truck speed by means of a not linear function of
the accelerator position, as to provide a better resolution of the speed control
when the truck is moving slowly.
For the definition of such response, the following parameters are used:

THROTTLE 0 ZONE [% of MAX VACC]

THROTTLE X1 POINT [% of MAX VACC]

THROTTLE Y1 POINT [% of MAX SPEED]

THROTTLE X2 POINT [% of MAX VACC]

THROTTLE Y2 POINT [% of MAX SPEED]

THROTTLE X3 POINT [% of MAX VACC]

THROTTLE Y3 POINT [% of MAX SPEED]
The speed remains at the FREQUENCY CREEP value as long as the voltage
from the accelerator potentiometer is below THROTTLE 0 ZONE. Basically this
defines a dead zone close to the neutral position.
For higher potentiometer voltages, the speed setpoint grows up as a polygonal
chain defined by the following table of points.
