4.2.2.3 Gyro Ki Gain (Integral Gain)
Parameter
Gyro Ki Gain
Gyro Ki Gain determines how much the Gyro reacts to slow changes in direction.
When this parameter is set correctly, the wheelchair will drive in a straight line over
significant distances and it will not veer when it drives on sloping terrain.
When this parameter is set too low, the Gyro effect will be less and the benefits
described above are reduced.
When this parameter is set too high, the chair may start to swerve slightly from left to
right when driving in a straight line, and when turning, the chair may keep on turning
a bit more after the user already has stopped turning.
4.2.2.4 Gyro Kfr Gain (Filtered Response Gain)
Parameter
Gyro Kfr Gain
The Power Module compares the actual movement of the chair with the joystick
input (the intended direction). If the user has a tremor, the joystick input does not
always accurately represent the intended direction of the chair.
To compensate for this, the joystick input is filtered before it is compared with the
actual movement of the chair. Gyro Kfr Gain determines how much the joystick input
is filtered.
0
- Maximum filtering is applied
255 - The joystick input is not filtered at all
For normal use, no filtering is needed - set this parameter between 200 -255.
Set this parameter to lower values if the Gyro module overcompensates due to
sudden unintended joystick movements.
If this parameter is set too low, the chair response may feel delayed.

Possible Values Default
0 - 255
Warning:
Excessively large values of Gyro Ki Gain can be dangerous. Values of Ki in
excess of that required to meet a specified performance objective should be
avoided.
