The acceleration of the powerchair can be adjusted with the
Forward Acceleration (5.3.7.3), the Reverse Acceleration (5.3.7.7) and the
Turning Acceleration (5.3.7.11) parameters.
Deceleration is the rate at which the speed decreases after the joystick has been
returned to the centre position.
Too high
• Too sensitive
• Jerky
Too low
• Unresponsive
• Long delays
Good
• Smooth
• Dependent on user
and environment
SPEED
Too low
• Unresponsive

The deceleration of the powerchair can be adjusted with the
Forward Deceleration (5.3.7.4), the Reverse Deceleration (5.3.7.8) and the
Turning Deceleration (5.3.7.12) parameters.
Note:
The UCM applies the acceleration and deceleration algorithms to
the Speed Demand value after the speed limiting functions.
Warning:
Too high or too low acceleration / deceleration settings can result in
potentially dangerous chair behaviour and lead to injury.
