Adjust Quadrant Operation; Adjust Drive Directions - Invacare LiNX Service Manual

7.7 Adjust quadrant operation

This parameter sets the drive function's user input to operate
in 3–quadrant (3Q)or 4–quadrant (4Q) mode. Typically, the
4Q mode is chosen with joystick-based inputs or arrays, that
provide 4 quadrants, for example, a Sip and Puff array. The
3Q mode is chosen for user inputs that provide 3 quadrants,
for example, a head array.

The options are:
• 4Q Operation
• 3Q - Forward Only
• 3Q - Reverse Only
• 3Q - Manual Toggle
• 3Q - Automatic Toggle
4Q Operation
When 4Q Operation is selected, each quadrant is assigned a
unique direction from forward, reverse, left and right, this is
the default mode. To change these default directions, the
quadrants can be reassigned with a different direction by
setting the following parameters:
• Forward Quadrant Operation
• Reverse Quadrant Operation
• Left Quadrant Operation
• Right Quadrant Operation
It is not necessary that all quadrants are assigned unique
directions. If required, one or more quadrants can share the
same direction. For example, Forward Quadrant Operation
and Reverse Quadrant Operation can both be set to
Forward. For more information about adjusting the drive
direction, refer to 7.7.1 Adjust drive directions, page 65.
