The programmable options are On and Off.
GENERAL – FRONT WHEEL DRIVE
11.11 FRONT WHEEL DRIVE TYPE
Front Wheel Drive Type selects specific specialist software for front wheel drive wheelchairs
If Front Wheel Drive Type A, this parameter electronically alters the shape of the joystick gate. This has the effect of damp ing
the turning rate of the wheelchair between the 9 o clock and 3 o clock joystick positions.
If Front Wheel Drive Type is set to B, this parameter sets threshold which, if exceeded, then both forward and turn speeds are
reduced, but the turning radius of the wheelchair remains unchanged. Type B can be used to increase the steerability of the
wheelchair at speed.
11.12 FRONT WHEEL DRIVE
Front Wheel Drive adjusts the operation of the specialist software for Front Wheel Drive Wheelchairs.
This selects specialist software for front wheel driven wheelchairs.
The programmable range is 0% to 100% in steps of 1%.
If set to 0%, then “normal” software for rear wheel driven wheelchairs is employed.
If set to any other value then front wheel drive software is employed. A higher value makes the software more suitable for
faster wheelchairs.
11.13 FWD ACCELERATION LIMIT
FWD Acceleration Limit sets the limit of forward acceleration when exiting a turn.
This limits the forward acceleration of the wheelchair when straightening out of a turn and helps prevent loss of traction.
The programmable range is 0% to 100%.
GENERAL – ADVANCED ELECTRONIC STABILITY (AES)
11.14 ADVANCED ELECTRONIC STABILITY
Advanced Electronic Stability sets whether the specialist stability software is turned on.
If set to On, AES detects if one wheel is running at a higher load and hence is running more slowly. If so, the speed of the other
wheel is reduced accordingly to compensate for any steering offset.
AES can be used to minimize front wheel drive spins, fish-tailing and veering, both on the level and on a camber. The overall
effect is to compensate for the wheelchair’s centre-of-gravity being shifted from the axis of the drive wheels, as is the case on
front wheel drive chairs.
If set Off, then the function is disabled.
