The parameter is used to set the percentage of the maximum motor

resistance that will be applied, i.e., (
for increased load caused by uneven terrain.
The trade-off in setting this parameter is that as ability to overcome load
disturbances increases, operating smoothness decreases. A high
value will allow the vehicle to continue creeping at a low speed, even though it
has just contacted a bump in the threshold of a doorway. But if
is set too high, it may make the vehicle "jumpy" during normal driving. Small
throttle movements in this case may no longer provide gentle linear accelera-
tion, but instead initiate accelerations with a sharp jerk. Therefore, the tuning
goal is a balance between adequate load disturbance response and normal ac-
celeration/deceleration response.
The normal range for
numbers provide stiffer, stronger response. If the value needs to be much larger
or smaller than this range to achieve acceptable performance, the
probably not been set up correctly and should be checked. Note: Largely dif-
ferent settings for
