5 Suggested programming procedure

CAUTION!
Risk of injury or damage
– Perform following procedure in a large open
environment, preferably outdoors. Make sure
wheelchair cannot crash into other people or
objects.
– Be prepared for unexpected wheelchair
movement in event of a faulty installation.
– If wheelchair becomes uncontrollable, perform
an emergency stop by turning LiNX system off.
The following outlines a suggested programming procedure
for setting up the LiNX system. It is not prescriptive and
should be used as a guideline only.
The following chapters show the preferred order in which
to program the parameters, what effects the parameters
have on the wheelchair and also how the various parameters
interact with each other.
1. Power-up test
2. Check motor orientation
3. Set load compensation
4. Adjust speed settings
5. Adjust acceleration settings
The programming procedure is suitable for LiNX systems with
or without a LiNX Gyro module fitted.
• For gyro-based systems, perform steps 1–3 without
the gyro connected and then steps 4 and 5 with gyro
connected.
5.1 Step 1 – Power-up test
Before programming, ensure that the system powers up
successfully. Press and release the power button on the
remote module. The status indicator should light green.
If the battery cable or loom has not been correctly
connected, the status indicator does not turn on.
If the status indicator flashes red, check the motors and
park brakes as they may not have been connected properly.
For more information about error codes, refer to the user
manual of the remote.

5.2 Step 2 – Check motor orientation
Step 2 ensures that the motors are configured correctly.

Check for Motor Inversion
To detect motor inversion, deflect joystick slightly forwards.
• If wheelchair moves backwards instead of forwards,
toggle both Left Invert and Right Invert parameters.
• If wheelchair turns on the spot, only one motor
is inverted. To begin with, just toggle Left Invert
parameter and deflect joystick forwards again. If
wheelchair moves backwards, wheelchair now has both
motors inverted. Toggle Left Invert and Right Invert
parameters to fix this issue.
Before continuing, make sure that wheelchair moves
correctly forwards and backwards.
Check for Motor Swap
To detect motor swap, deflect joystick to left. If wheelchair
moves right, toggle Swap parameter.
Before continuing, make sure that wheelchair moves
correctly forwards, backwards, left and right.
5.3 Step 3 – Set load compensation
Load compensation relies on accurate motor resistance
values to work effectively. The motor resistance values can
