Compensation settings

Road Compensation is a unique feature in the mo-vis joysticks. When you are driving on an uneven road with a special control mounted in a tray, or on an arm (or any other place where tremblements may be amplified), it can be very difficult to maintain control over the electric wheelchair and sometimes even unsafe. You can make this easier and safer, by enabling the Road Compensation.

There is an accelerometer inside the joysticks and when it vibrates, it sends a signal to the wheelchair to slow down to a predefined parameter.

Setting Description Parameters
Compensation factor Lowers forward/backward (Y) driving speed on rough terrain.
Wheelchair type and weight have an impact on this factor:
  • Heavy loaded wheelchairs may need to lower the setting to 'Weak'.
  • Light wheelchairs may need to increase the setting to 'Strong'.
  • If the joystick is mounted on a location that may multiply the value of a shock (e.g. on an arm), the setting should be lowered to 'Weak' or 'Very weak'.
  • Frontwheel-driven wheelchairs are less affected by this factor than rearwheel-driven wheelchairs.
 Very weak Almost no slow down
Weak Slows down less compared to normal
Normal Default setting
Strong Slows down more compared to normal
Very strong Slows down more compared to strong
X compensation To limit the steering reaction if the wheelchair overreacts on steering commands. This may happen due to compensation on the X direction that prevents the wheelchair to overcome an obstacle due to the loss of torque. The value is based on the compensation in Y direction. None No compensation
1/2 Y X = 50% of Y level
2/3 Y X = 66% of Y level
Equal Y X = 100% of Y level
(De)activation pattern Active if compensation mode is set to 'Manual'.
To activate/deactivate: nudge the joystick Forward + Backward + Forward.
  • Agile users may be able to execute this pattern quite quickly.
  • Set this parameter according to the agility of the user.
Note: 'Slow' may cause the wheelchair to drive while executing the pattern.
 4s Min.
5s Default
10s Max.
Road Compensationor Profile 1/.../7 (R-net joystick) Defines activation of the compensation algorithm.

For R-net: can be set individually for each profile.

 Off Always deactivated
Manual (De)activated manually by the user
On Always activated

Tilt settings

Setting Description Parameters
Tilt The joystick can detect the joystick tilt.

The wheelchair will stop driving when the parameter is set to 'On' and the joystick is tilted more than 70° (default) in any direction.

The tilt sensor inhibit becomes inactive again when the angle becomes less than 65° (default).

The use of this functionality certainly makes sense when a mo-vis joystick is integrated in a tray or other tilting surface/mounting aid.

Note: The tilt sensor response time is less than or equal to 1s.
 On Tilt is enabled
Off Tilt is disabled
Angle Here you can choose at which angle the joystick will become inactive, when the tilt setting is enabled. 0° Min.
70° Default
180° Max.

Input settings for joysticks with Omni connection

For joysticks with Omni connection, you can only program the yellow tip.
Setting Description Parameters
Switch type Specification of the button connected to the yellow tip.
Note: It is only useful to program this as a safety switch with an Omni2 display.
 None This input will be ignored.
Normal open You can connect a standard button or a safety switch (e.g. mo-vis Twister Pro). When the safety switch fails, it will not be detected and no warning is given.
Safety switch You must connect a safety switch. When the safety switch fails, a warning will be given.

For more information about the Twister Pro and its safety switch functionalities, please refer to the Twister Pro Installation manual.

Note: You have to program the safety switch both here in the mo-vis Configurator and in the R-net Programmer.

For a Multi Joystick, there is the additional option to program the yellow tip on the sensor itself. This parameter is called Specific Input Setting.

Another parameter that you can set is the Debounce Timer. This will be applied to all connected buttons except for the on/off button!

Setting Description Parameters
Debounce timer The input button has to be pressed for longer than the debounce timer, before it is seen as an input. It can be useful to increase this timer, in case the user has a tremor. 50 mS Min./Default
2500 mS Max.
10 mS Step

Input settings for joysticks with R-net connection

For joysticks with an R-net connection, you can program both the yellow and the red tip.

Yellow tip:

Setting Description Parameters
Switch type Specification of the button connected to the yellow tip. None This input will be ignored.
Normal open You can connect a standard button or a safety switch (e.g. mo-vis Twister Pro). When the safety switch fails, it will not be detected and no warning is given.
Safety switch You must connect a safety switch. When the safety switch fails, a warning will be given.

For a Multi Joystick, there is the additional option to program the yellow tip on the sensor itself. This parameter is called Specific Input Setting.

Red tip:
Setting Description Parameters
Switch type Specification of the button connected to the red tip. Normal open You can connect a standard button or a safety switch (e.g. mo-vis Twister Pro). When the safety switch fails, it will not be detected and no warning is given.
Safety switch You must connect a safety switch. When the safety switch fails, a warning will be given.
Auto detect You can connect a standard button or a safety switch. When a safety switch is connected and it fails, a warning will be given.

Auditive feedback

Setting Description Parameters
Error/warning beep When the control goes into error or warning, it will show the flash code on the LED (seeError codes) . With this setting, you can choose to also hear it via the buzzer. Off No beep when in error/warning
On Beep sounds the flash code when in error/warning(see Error codes)
Road compensation beep This parameter is only relevant, when you have set Road Compensation to manual. In that case, a sound will be heard when the road compensation is enabled/disabled.
  • Enabled: 1 short beep
  • Disabled: 2 short beeps
 Off No beep when road compensation is enabled/disabled
On Short beep(s) when the road compensation is enabled/disabled
Movement beep This parameter is only relevant, when you have set Road Compensation to manual. In that case, a sound will be heard to indicate when the (de)activation pattern is stopped or when a wrong pattern is executed. This will let the user know that the wheelchair will start to move. Off No beep when road compensation (de)activation pattern is cancelled
On Long beep when road compensation (de)activation pattern is cancelled
