Joystick Switch Threshold - Invacare LiNX Service Manual

Invacare® LiNX
Operation
Toggle

Proportional
Not Used
d. Speed: For the switch-type operations (Switched,
Latched, Toggle, Toggle / latched), this parameter
applies the speed of the motion when the joystick
crosses the Joystick Switch Threshold.
For the proportional operation, this parameter sets
the maximum speed at which the motion will travel
when the joystick is deflected to 100 % of its travel.
For all other positions of joystick deflection the
applied speed will be scaled down accordingly.

Purpose
Activates the motion in
one direction (extend
or retract) for the
duration that the
joystick's position is
greater than Joystick
Switch Threshold. The
motion is deactivated
when it reaches its
end-of-travel or when
the joystick's position is
less than Joystick Switch
Threshold. The direction
of the motion toggles
between extend and
retract for each new
activation.
Activates and latches the
motion in one direction
(extend or retract) by
momentarily deflecting
the joystick across
the Joystick Switch
Threshold. The motion
is deactivated when
the motion reached
its end-of-travel or the
joystick is deflected
again across the Joystick
Switch Threshold.
Deflecting the joystick
forwards /backwards
activates the motion in
the extend / retract
direction for the
duration that the joystick
is deflected. The motion
is deactivated when it
reaches its end-of-travel
or when the joystick is
returned to the neutral
position. The speed of
this motion is controlled
by the amount of
deflection from the
neutral position and
scaled further by using
the Speed parameter.
No operation.

7.6 Joystick Switch Threshold

Sets the percentage of joystick movement required to
activate an output when the joystick is operating as a
switched input device.
When the joystick is used as a switched input device, this
parameter specifies how far the joystick has to be pushed
before its state changes (OFF B to ON A) and activates an
output. The Joystick Switch Threshold value is a percentage
of the joystick's full travel and should be set according to the
user's needs. For example:
•
for users that have difficulty moving the joystick , set
Joystick Switch Threshold to a low value, such as 40
% or less,
•
for users that lack fine motor control or are subject to
hand tremors, set Joystick Switch Threshold to a high
value, such as 80 %, to avoid unintentional switching.

Set the desired percentage.
Tremor dampening
Use this parameter to reduce the effect of hand tremors
on the joystick. Low values are suitable for users with low
frequency (slow) tremors. Higher values will suit users with
higher frequency (fast) tremors. Setting the parameter value
to 0 % results in no tremor dampening.
