PVED-CLS AUX— flow limitation tuning advice
1. Remove flow limitation (1000 for all 3 flow limits) and drive the machine first slowly and then at
increasing speeds.
2. On each trial, steer full left or right with the joystick.
Vehicle tipping hazard!
Operate carefully to avoid tipping the vehicle.
If the machine does not feel controllable at a given vehicle speed, use the flow limitation to begin to
decrease flow allowed at that speed.
3. Iterate until the operator can move the joystick as quickly as possible at any speed and avoid tipping.
CAN logging can also be implemented to monitor vehicle speed and flow set-points from the Vehicle
Speed message and Status Message 4 which are described in the PVED-CLS Communication Protocol
document. Scatter plotting flow set-points vs. vehicle speed should yield a curve that can be reflected
with the AUX Flow Limitation.
PVED-CLS AUX— closed loop joystick
AUX Wheel Angle Limit is used with Closed Loop Joysticks to limit the maximum wheel angle as the
vehicle speed increases. This function scales all joystick wheel angle commands based on vehicle speed.
See Section 11.10 Closed Loop Joystick – Vehicle Speed Dependent Wheel Angle Limitation in the User
Manual for more info.
Parameter Conditions for value change
P3720 Set to desired wheel angle limit [degree] at 0 km/h (see graph below)
P3721 Set to desired wheel angle (y-axis) at desired vehicle speed in km/h (P3723)
P3722 Set to desired wheel angle (y-axis) at desired vehicle speed in km/h (P3724)
P3723 Set to desired vehicle speed in km/h (x-axis) at desired wheel angle (P3721)
P3724 Set to desired vehicle speed in km/h (x-axis) at desired wheel angle (P3722)
