The PROFI CAR offers the following facilities for setting up the steering function:
∙Servo norm, centre and travel right/left (è6.1)
These settings are used to adjust the servo to match your car’s mechanical system, and at the same time determine the maximum steering travel and the centre setting for straight running.
∙Steering MINTRA (MINimum TRAvel) (è6.2)
You can adjust the steering travel using the digi-adjustor while you are running the car. This enables you to fine-tune the steering response to suit changing course conditions or vehicle characteristics (e.g. tyre temperature). This menu point allows you to define the smallest steering travel which you can set by rotating the digi-adjustor. MINTRA avoids the danger of suddenly having no steering control if you turn the adjustor too far by mistake. The smallest value you can set is 30%.
∙EXPO (è6.3
By applying EXPOnential to the steering function, you can make the steering response of your car more or less sensitive around the centre position.
∙Steering travel and trim increment (è6.4)
(„T“ menu, menu point „TRIM“)
The effect of trim rocker A (steering centre point) and the digi-adjustor (steering travel) can be set to FINE (1% increments), MEDIUM (2% increments) or COARSE (4% increments). The selected setting also applies to all other trim rockers.
6.1.Adjusting the steering servo
The first step is to set the signal norm and the direction of rotation for the servo, followed by the settings for left (L), straight ahead (•) and right (Œ). These basic settings ensure that servo 1 (steering servo) is set up correctly to suit the characteristics of your model.
The drawing on the right shows an example of the settings available in the “S-TRA” menu. The stated angles (0°/45°) show what the servo “can do”. The adjustments points „L“ and „Œ“ define the maximum travel set for the steering servo. To adjust either of these points you must turn the steering wheel in the corresponding
direction. At the „•“point you determine the servo setting for “straight ahead”.
The “S-NORM” menu point is used to select the signal format (MULTIPLEX or UNIVERSAL) and direction of rotation for the servo. “MULTIPLEX norm” means that the pulse width for the centre position is 1.6 ms, and the full range is +/- 0.55 ms. UNIVERSAL servos operate on 1.5 ms +/- 0.5 ms. If the selected signal format does not match your servo, the centre position and travels will not be correct.
The “S-TRAV” menu point is used to set the centre position and steering travels for right and left.
