The Drive menu contains the key parameters for the forward and reverse speed, acceleration
and operating feel of the wheelchair. There are separate Drive menus for Prole 1 and Prole 2.
Care must be taken to differentiate between the parameters that are affected by the speed limits
(speed mode settings) and the parameters affected by the actual current speed of the wheelchair.

Fwd Max
Speed
1 – 100 % Maximum forward speed with speed limit set to 100%.
Fwd Min Speed 1 – 100 % Maximum forward speed with speed limit set to 0%.
Fwd Accel High
Speed
1 – 100 % Forward acceleration with speed limit set to 100%.
Fwd Accel Low
Speed
1 – 100 % Forward acceleration with speed limit set to 0%.
Fwd Decel High
Speed
1 – 100 %
Rate of deceleration when the wheelchair is driving forward at high
speed.
Fwd Decel Low
Speed
1 – 100 %
Rate of deceleration when the wheelchair is driving forward at low
speed.
Rev Max Speed 1 – 100 % Maximum reverse speed with speed limit set to 100%.
Rev Min Speed 1 – 100 % Maximum reverse speed with speed limit set to 0%.
Rev Accel High
Speed
1 – 100 % Reverse acceleration with speed limit set to 100%.
Rev Accel Low
Speed
1 – 100 % Reverse acceleration with speed limit set to 0%.
Rev Decel High
Speed
1 – 100 %
Rate of deceleration when the wheelchair is driving backward at high
speed.
Rev Decel Low
Speed
1 – 100 %
Rate of deceleration when the wheelchair is driving backward at low
speed.
Tapered Decel
Speed
1 – 100 % Speed at which a second, more gradual rate of deceleration is cal-
culated and activated for a gentler stop.
Drive Softening 0 – 40 % Higher values result in gentler acceleration.
Tremor Sup-
pression
1 – 100 %
Higher values result in more pronounced ltering to suppress fast
hand movements.
Quick Stop
Factor
1, 2, 3
Multiplier for the rate of deceleration when the joystick is quickly
moved from the forward to the reverse position. A value of 2 makes
deceleration 2 times as fast; a value of 3 makes deceleration 3 times
as fast. The value 1 deactivates this parameter.
Emergency
Stop
60 – 100 %
Rate of deceleration when turning off the key-operated switch or in
case of an error.
