3.3 Setup procedure for the Gyro
3.3.1 Preparation
The Gyro module gives the most comfortable results on a chair that has already been
set up to provide optimal performance and steering stability without the Gyro control.
If the chair has not been set up for steering stability, the Gyro will still correct the
direction of the chair and keep the chair straight, but it has to make bigger
corrections which results in jerky and uncomfortable driving. Please set up the
following parameters first, before activating the Gyro control.
Load Compensation
Speed @ Maximum
See the DX System Manual on how to set up these parameters with Wizard.
Parameters that can help to keep the chair straight on Front Wheel Drive chairs:
Non-Linear Turn decreases the sensitivity of the joystick for small sideways joystick
deflections. This makes it easier to keep the chair straight when unintended small
joystick movements occur.
A reduced Turning @ Full Speed decreases the sideways sensitivity of the joystick
when the joystick is fully deflected forward. This makes it easier to keep the chair
straight at full speed.
After setting up the above parameters, check that the chair is already reasonably
driveable without the Gyro control. If this is the case, proceed to set up the Gyro.
3.3.2 Gyro set-up procedure
The DX2 Gyro works by combining input demand from a joystick or switch source with
digital gyroscopic information about the direction that the wheelchair is tracking.
When the system detects that the wheelchair is deviating from the intended course of
direction it automatically corrects the path of travel. The system has four key
parameters that must be specifically tuned to each wheelchair design configuration:
The Angular Speed Scalar calibrates the Gyro to a particular wheelchair
configuration. This is the most critical value and must be set up before any
other Gyro values are adjusted. A calibration tool is included for this in the
latest Wizard PC tool.

Note:
Ensure your Wizard is updated to the latest available version (version 5.6.6 or
later), which contains the Gyro Tuning Plug-in, and three new system builder
templates for Gyro. You can create a new Gyro programme using the
templates, or you can convert an existing DX2-PMA90L programme into a
DX2-PMALG version. Under "Tools", click on "Change Module Version" and
select the Power Module and change this to the DX2-PMA90LG Version.
Repeat this for "Change Module Type". You need to change both Version
and Type for the conversion to work properly.
