5.9.5 3 Step Up/Down

In this mode, you can step up or down through one of three
fixed speeds. The speeds available are 33 %, 67 % 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 33 % 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.
Gentler Rate
1. Give short drive demand, less than one second, in
opposite direction (a reverse demand when driving
forwards or a forward demand when driving in reverse)
or
let Latch Drive Timeout expire.
