M1.6-1 Accelerator characteristic “Lin/Curv”
This parameter defines the accelerator pedal characteristic: Linear or Curved.
• If set to 0, the controller will apply a linear accelerator input.
• If set to 1, the controller will apply a curved accelerator input.
The definition of each type is detailed below:
Linear: For input values of 0%, 50% and 100%, the output will be 0%, 50% and 100%.
Curved: For input values of 0%, 50% and 100%, the output will be 0%, 25% and 100%.

M1.6-2 Accelerator type ”AccelTyp”
This set the acceleration type.
• If set to 0 (normal), a normal accelerator that can operate with direction switches is selected.
• If set to 1 (wig-wag), a Wig Wag accelerator is selected and no direction switch is required. The voltage
admitted range is from 0.2V to 4.5V. For a proper operation, the wig-wag potentiometer connected
to “Pin A9 Analogue AD1 i/p Accelerator -- Potentiometer” has to operate within this range. Also
parameter “M1.6-4 Accelerator pot minimum voltage level “AccMin”” has to be higher than 0.2V and
parameter “M1.6-5 Accelerator pot maximum voltage level “AccMax”” has to be lower than 4.5V. Both
have to correspond to the actual wig wag potentiometer accelerator range.
The wig-wag behavior is represented in the following image:
