The sensor characteristics needs to be mapped, according to Figure 22. The steer angles @ 33% (P3836), 67% (P3837)
and 100% (P3838) of the voltage base (P3839) should be mapped, where voltage base is:
The absolute voltage [mVolts] from the WAS, going from neutral to right most position, when maximum possible steer
angles can be achieved on the vehicle + some tolerance.

ANALOGUE JOYSTICK CALIBRATION

As per default, PVED-CLS will boot-up in Analogue joystick calibration service mode after one of the below conditions
is reached
•
If WAS interface i.e.P3244 is set to CAN AND AUX Present i.e. P3239 is set to TRUE and AUX Type i.e. P3240
is set to analogue joystick, and a successful WAS calibration has been completed.
•
If WAS interface i.e.P3244 is set to NONE AND AUX Present i.e. P3239 is set to TRUE and AUX Type i.e.
P3240 is set to analogue joystick.
From here, the analogue joystick auto-calibration routine from the Danfoss PLUS+1 SERVICE TOOL can be used.
Additionally, at every boot-up, the PVED-CLS validates the Analogue Sensor calibration data sectors (for analogue
Joystick), so for the "Analogue joystick" (see 17.4.5)
PVED-CLS will enter "Analogue joystick calibration", If either of the below condition fails
