Operation and function of electronic slip control
Radar sensor technical specifications
Two signals are needed to determine slip: one for the actual speed and one for the theoretical.
A bevel pinion speed sensor B015 (Hall-effect sensor) is used to measure the theoretical speed.
A radar sensor A011 is used to measure the actual speed.
The radar sensor A011 works on the Doppler principle.
It supplies a pulse frequency which is proportional to the actual speed.
The pulse frequency depends on the mounting angle of the radar sensor A011 on the tractor.
On Fendt tractors the radar sensor A011 is mounted at an angle of 53
°
to the road surface.
With this mounting angle the radar sensor A011 has a pulse frequency of approx. 95 pulses/m.
The EPC ECU A005 converts the pulse frequency of 95 pulses/m to the standardised signal of
130 pulses/m and transmits it to the implement socket X007.
