• See flow chart 020903020.
The following tables show the standard settings, of which 9 parameters apply to driving.
These settings can be changed.

The following parameters can be set:
1. Maximum speed forward
2. Accelerate forward
3. Delay forward
4. Maximum speed forward
- Accelerate reverse
5. Delay reverse
6. Maximal running speed
7. Turn gear
8. Turn delay
9. Buffing joystick
Directions can be set using this (the higher the percentage, the slower the wheelchair reacts to the joystick).
By pressing 'Up' and 'Down' this setting can be changed.
10. Joystick choice
Gives the choice of operating the wheelchair with the joystick in the controller, or by an external joystick.
Pressing on 'Swap' determines the choice:
• Local: Joystick in controller.
• Remote: external joystick.
11. Joystick counter
The joystick can be placed both on the right and the left hand side.
By turning the joystick 180° one has created a situation in which steering forward becomes driving in reverse.
This is often used with chin steering.
12. Spring compensation
This involves a possible correction to compensate a deviation in speed of the motors.
If, for example, the wheelchair with a joystick position deviates to the left, the 'spring compensation' should be
set to the right. Only in very exceptional cases will such a correction be required.
13. Load compensation
Changing this parameter can lead to very dangerous situations!
This setting determines the drive of the motor (internal resistance of the motor in Milliohms depending on the
type of motor).
14. Joystick calibration
When the wheelchair leaves the factory, the joystick is calibrated. If for some reason the joystick must be
recalibrated, this should be done as follows:
• Press Begin.
• Move the joystick forcefully to the left or right along the outermost stop, and let the joystick come back into
neutral position.
• Press End.
