4.4.2.3
Throttle Neutral Offset
Parameter
Possible Values
Default
HHP

Std Adv
Throttle Neutral Offset
-0.63 - +0.62 V
0 V
Set this to account for any slight mechanical offset between the throttle neutral position and
the centre position of the throttle wiper. The offset is an absolute voltage above or below
neutral.
Use the HHP to calibrate the unit instead of setting a value manually, see
(4.1.1.3) for details.
The default neutral value is dependent on the value of the
parameter (4.4.2.1):
Wig-wag and Uni-polar both have the default neutral value at 2.5 V.
Single-ended has its default neutral value at 0 V +
Minimum Throttle Voltage
In this case all negative values of
Throttle Neutral Offset
are ignored and all positive values
are multiplied by 2, which mean that a Wizard setting of 0.5V will produce an actual
neutral offset of 1.0V.

Throttle Full Scale Deflection
20 - 100 %
75 %
Set the percentage of total throttle movement that will result in full speed.
The scale of this parameter ranges between
Throttle Neutral Offset
(0%) and
Maximum
Throttle Voltage/ Minimum Throttle Voltage
(100%)
.
For example, if a mechanical stop restricts the throttle from moving more than 60% of its full
electrical travel, set this parameter to 50% to make sure that the scooter can still reach
maximum speed.
