6.5.5.7 Load Compensation Damping
Parameter Possible Values Default HHP Lite Std Adv
Load Compensation Damping 0 - 60% 25%
✓
Load Compensation Damping is used to dampen the effects of the load compensation to
avoid bucking and instability at high Load Compensation settings.
The recommended value for this parameter is between 25 – 50%. It is important to avoid
higher as this can lead to the load compensation continuing to be applied when the motor
current has fallen, causing problems such as the scooter continuing to surge forward after,
for example, climbing an obstacle.
The Load Compensation Damping parameter interacts with the following parameters:
l
Remembered Load Compensation
l
Load Compensation
l
Park Brake Neutral Delay
When setting these parameters, follow the method below:
1. Adjust the Load Compensation parameter first to give correct driving performance.
2. Adjust Load Compensation Damping to minimise bucking, while keeping the system
responsive.
3. Adjust the Park Brake Neutral Delay parameter to provide acceptable rollback on
slopes and prevent jerking – higher values decrease jerking but give more rollback
and vice versa.
4. Adjust the Remembered Load Compensation to give acceptable starting performance
when the park brake is released, both when driving on the flat and on slopes. (Note:
this parameter has no effect if the scooter stops and restarts driving quickly such that
the park brake is never applied.)
6.5.5.8 Remembered Load Compensation
Parameter Possible Values Default HHP Lite Std Adv
Remembered Load Compensation 15 - 60% 50%
✓
The controller records the amount of motor current that is required to hold the scooter
stationary just before the park brake is applied. When the scooter starts off again, this
recorded value is used to calculate the starting load compensation value to reduce the
amount that the scooter rolls back. The Remembered Load Compensation parameter
adjusts the amount of this starting load compensation.
The Remembered Load Compensation parameter interacts with the following parameters:
l
