Slip control performance test
The accuracy of the "theoretical speed" signal (A) from the bevel pinion speed sensor B015 is a
function of the tractor speed
Text-module
Bullet-List
●
Speed < 15 km/h (maximum display accuracy)
- Calibrating speed display
The ECU A002 counts the pulses per metre. The instrument panel A007 then calculates the
"theoretical speed" (A) from the number of pulses.

Bullet-List
●
15 km/h < speed < 20 km/h
- Enter tyre size.
The ECU A002 counts the revolutions of the bevel pinion shaft. The instrument panel A007 calculates
the "theoretical speed" (A) from the number of bevel pinion shaft revolutions and the input tyre
circumference.

Bullet-List
●
Speed > 20 km/h
Specified (maximum) tyre circumference in EOL program
(EOL = end of line)
The ECU A002 counts the revolutions of the bevel pinion shaft. The instrument panel A007 calculates
the "theoretical speed" (A) from the number of bevel pinion shaft revolutions and the maximum tyre
circumference specified in the EOL program.
The maximum tyre circumference specified in the EOL program limits the ultimate maximum speed.

Note:
The transitions between the speed ranges < 15 km/h, < 20 km/h and > 20 km/h are fluid.
In other words the calculation of the theoretical speed (A) becomes similar.
