Program Parameters

A number of user programs are available to each steering device. This enables programming flexible
functionality for each steering device such as:
•
Possibility to adapt the steering system to the working situation.
•
Personalized steering behavior (novice or expert level)
•
Customized/variable steering ratio/gain settings
•
Invert flow direction for e.g. backward steering
A number of programs are allocated to each steering device as shown in the table below. Each program
has a unique number which is used for requesting a new program from the MMI.

Flow command
At power-up, the lowest program number for each device is applied i.e. program 0 for steering wheel
sensor, program 20 for high priority steering device etc.
The program for a steering device becomes active as soon as the steering device is activated i.e. meets
the set-up criteria for when the PVED-CL shall regard a steering device as 'being used for steering'.
An overview of all program parameters can be found in appendix

Indexing Parameter

Each parameter has a unique index. Only one parameter can be accessed at a time. The system parameter
and steering device parameter indices are explicit and can be found in
