Interrupting Deceleration
When slowing down or stopping (except for an emergency
stop or control input configured for a stop), the deceleration
can be interrupted to resume driving.
1. Give drive demand for accelerating before speed has
reached zero, so speed accelerates to nearest higher
fixed speed.
5.8.6 5 Step Up/Down
In this mode, you can step up or down through one of five
fixed speeds. The speeds available are 20 %, 40 %, 60 %, 80
% and 100 % of the maximum pre-set reverse or forward
speed A of the selected drive card and then remain at that
speed for the programmed Latch Drive Timeout period as
long as no further demand is given.

Accelerating
1. Give drive demand in desired direction (forward or
reverse).
2. Release drive demand.
Wheelchair speed accelerates to 20 % of the maximum
drive speed.
3. Give forward demand when driving forwards or reverse
demand when driving in reverse to accelerate to next
fixed higher speed.
Give reverse demand when driving forwards or forward
demand when driving in reverse to decelerate to next
fixed lower speed.
Drive demand in opposite direction must
be quick, less than one second, otherwise
wheelchair stops.
4. Release drive demand.
New speed is held constantly.
Decelerating
When decelerating, the speed decelerates to the next lower
fixed speed (or zero if stopping) at one of two rates (normal
or gentle), depending on how the deceleration is triggered
(long or short demand) and if the optional slower rate is
configured by the provider.
Normal Rate
1. Give long drive demand, greater than one second, in
opposite direction (a reverse demand when driving
forwards or a forward demand when driving in reverse)
or
press external stop switch.
