setting is 10; it should remain at 10 before adjusting Tuning settings.
• Steering Response
Controls how well the vehicle holds the AB line. Increasing or decreasing this rate adjusts all three tuning
parameters (Motor Aggressiveness, Heading Aggressiveness and Cross-Track Error) simultaneously.
Increasing this rate may allow the vehicle to hold the AB line closer; but if adjusted too far it could cause
the vehicle to oscillate across the line. Hence, use this adjustment only after the OnTrac2 tuning parameters
have been adjusted to their correct values. The default of this setting is 10; it should remain at 10 before
adjusting Tuning settings.
Note: You can use this adjustment to account for different implements (as some pull harder than others),
ground conditions (more or less slippage) or increases and decreases in vehicle speed.

Tuning

The Tuning process is where you can adjust individual settings for Motor Aggressiveness, Heading
Aggressiveness and Cross-Track Error. Adjust the tuning parameters in the following order:
1. Set AB Line.
Note: To get an idea of how a parameter will affect how the vehicle drives, set the parameter at a very low
value, such as 3 or 4; and then at a very high value, such as 15 or 16. This will give a good indication of how
each tuning parameter affects performance.
• Motor Aggressiveness
How quickly or aggressively the OnTrac2 Mechanical Drive Unit motor moves the steering wheel. The
higher the Motor Aggressiveness Value the more responsive or aggressive the OnTrac2 Mechanical Drive
Unit will move the steering wheel. This value is limited by the maximum speed and torque output of the
OnTrac2 Mechanical Drive Unit.
Note: Set this value as high as possible, but if set too high it could cause the steering wheel to oscillate.

Steering, Heading and Cross-Track Error. For more information,
see "Tuning" on page 56.
• Line Acquisition
Controls the aggressiveness that a vehicle acquires an AB line.
Increasing this value will cause the vehicle to take a sharper angle
toward the AB line. Decreasing this value will cause the vehicle to
approach the AB line at a more gradual angle. The default of this
2. Adjust Motor Aggressiveness.
3. Adjust Heading Aggressiveness.
