Important
For OSPE/EHi; even though it will be possible to set a value of "No of turns" up to 8 turns, lock-to-lock, this is limited
by the Cylinder stroke volume; P3086 divided by OSP displacement, P3084. For EHPS, the limit will be the parameter;
Turns lock-to-lock EHPS, P3082.
Warning
Danfoss strongly recommends that the Steering programs are set up to ensure safe operation at any vehicle speed.
this implies that:
1. For every vehicle speed dependent steering program the configurable points shall result in a graph with
positive slope.
2. If a steering program is configured not to be vehicle speed dependent, it must be ensured that the configuration
allows safe driving at all possible vehicle speeds.
3. Unused steering programs shall be programmed with default values.
Failure to comply with the above rules may render this function inoperable or lead to undesirable steering
behavior!

Compensate steering sensitivity according to wheel angle range

PVED-CLS offers a feature to keep the steering sensitivity fixed if the physical max wheel angle range is changed due to
adding/changing tires.
