Parameter
Setting range Description
Power
Single steps
from 0 to 100%
Reduction of wheelchair power. Power indicates here the capacity of a
wheelchair to drive up a hill or to overcome an obstacle. When the value is
set to 100%, the wheelchair delivers full power. Values under 100% result
in a power reduction. This can be applied to prevent damage to doors or fur-
niture when the wheelchair is used indoors, for example. The values can be
set independently of one another in the driving profiles, i.e., separate profiles
can be defined for indoor and outdoor use.
If the value is set to less than 100%, the Boost function is automatically disa-
bled. This means that the power reduction is applied to the max. current limit.
Programming example:
Current limit = 80 amperes
Boost = 120 amperes
Boost duration = 5 seconds
Power (profile 1) = 100%
Power (profile 2) = 50%
This means that the R-Net control unit delivers a current of 120 A for 5 s in
Profile 1, then 80 A on a continual basis. In Profile 2, 50% of 80 A = 40 A is
attained without a boost.
Torque
Single steps
from 0 to 100%
This parameter can be used to increase the current for the motors at low
driving speeds. This is useful for overcoming obstacles such as doorsteps
or thick carpets or when the wheelchair rolls backwards. The parameter has
no effect at 0%. The recommended value is 80%, but this value should be
reduced if the wheelchair becomes too jerky.
Tremor Damping Single steps
from 0 to 100%
This parameter can be used to reduce the impact of a user's hand tremor on
joystick operation. The higher the set value, the greater the damping effect.
CAUTION!
When high values are entered to suppress tremors, pay particular
attention to the longer braking distance of the wheelchair.
7.4.3 Joystick parameters
The following parameters can be set under Controls/Joystick:
Parameter
Setting range Description
Joystick Forward
Throw
25% to 100%
in single steps
Used to set how far forwards the joystick must be moved before full forward
speed is reached.
This is particularly useful for users who do not have full movement of their
hands.
The percentage corresponds to the joystick movement required to reach full
forward speed. If it is set to 50% for example, the joystick only needs to be
moved halfway to reach full speed.
Forward throw can also be set interactively, i.e. with the user moving the joy-
stick (please see information following the table for details).
Joystick Back-
ward Throw
25% to 100%
in single steps
Used to set how far backwards the joystick must be moved before full reverse
speed is reached. This is particularly useful for users who do not have full
movement of their hands.
The percentage corresponds to the joystick movement required to reach full
reverse speed. If it is set to 50% for example, the joystick only needs to be
moved halfway to reach full speed.
Backward throw can also be set interactively, i.e.with the user moving the
joystick (please see information following the table for details).
