6.5.5.15 Max Motor V Demand Limit
Parameter Possible Values Default HHP Lite Std Adv
Max Motor V Demand Limit 50 – 100% 100%
✓
This parameter determines when to reduce Maximum Motor Voltage based on the throttle
demand. If the throttle demand is above this level, the Maximum Motor Voltage is reduced.
Note that if this parameter is set too low, then driving on a flat surface could be affected, as
it will add a short burst of additional acceleration when stopping.
For more information, see 6.5.5.18 Downhill Speed Limiting.
6.5.5.16 Max Motor V Ramp Down Time
Parameter Possible Values Default HHP Lite Std Adv
Max Motor V Ramp Down Time 0.5 – 2.5s 2.0s
✓
This parameter sets the time it takes to ramp down the Maximum Motor Voltage when
starting to drive down a slope. If this time is set too low, going down a short slope will also
result in a noticeable speed reduction.
For more information, see 6.5.5.18 Downhill Speed Limiting.
6.5.5.17 Max Motor V Recovery Time
Parameter Possible Values Default HHP Lite Std Adv
Max Motor V Recovery Time 0.5 – 2.5s 2.0s
✓
This parameter sets the time it takes to recover Maximum Motor Voltage to its programmed
value when leaving a slope. If this time is set too short, speed will increase suddenly to
match the throttle demand.
For more information, see 6.5.5.18 Downhill Speed Limiting.
6.5.5.18 Downhill Speed Limiting
When driving a scooter down a long slope at maximum speed, some scooters may
experience an unintentional speed increase, especially large, high speed scooters (15kmh
or faster). In most cases this unintentional speed increase is undesirable. This section
describes how the controller can be programmed to either prevent or reduce this increase.
Before setting up downhill speed limiting, ensure that Load Compensation and Maximum
Motor Voltage are already set up correctly.
There are four parameters that are used to set up the desired behaviour:
l
Max Motor V Scalar
l
Max Motor V Demand Limit
l
Max Motor V Ramp Down Time
l
Max Motor V Recovery Time
