Joystick Switch Threshold - Invacare LiNX Service Manual

Invacare® LiNX
Choose one of the switch-type modes to operate the
motion at a fixed speed. The motion is activated
when the joystick is deflected past the Joystick Switch
Threshold B into either the forward A or backward
C quadrants. Refer to 7.6 Joystick Switch Threshold,
page 64 how to modify the Joystick Switch Threshold.
Choose the proportional-type mode to operate the
motion at a speed that is proportional to the joystick's
position. The motion is activated when the joystick is
deflected out of neutral into either the forward A or
backward C quadrants.
If the joystick is not used to control this motion, then
set this parameter to Not Used.
Operation
Switched
Latched
Toggle
80
Purpose
Activates the motion in
the extend / retract
direction for the
duration that the
joystick is deflected
forwards / backwards
and its 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 the Joystick
Switch Threshold.
Activates and latches
the motion in the
extend /retract direction
when the joystick is
momentarily deflected
forwards / backwards
across the Joystick
Switch Threshold. The
motion is deactivated
when the motion
reaches its end-of-travel
or the joystick is
deflected again across
the Joystick Switch
Threshold.
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.
Operation
Toggle / latched
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.

9.5 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:
Purpose
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.
