10.7 SOFT-STOP
The soft-stop function can limit the allowed maximum flow delivered to the steering cylinders in proportion to the relative
wheel angle. The function is mirrored to both sides (left- and right-end stop). The functions control algorithm will
implement a linear interpolation between two points, Point A and Point B.
• Point A (1000-P3562, 1000)
• Point B (1000-P3566, P3564)
Figure 46
The range is from 0 to 1000 [IR] for P3562, P3564 and P3566 (i.e. relative wheel angle and soft-stop flow limit,
respectively).
The values recommended by Danfoss are P3562 set to 400, and P3564 and P3566 set to 0.
Important
For absolute wheel angles lower than the one specified at Point A maximum flow is available.
Important
If soft-stops are not required, those can be eliminated by setting P3564 to 1000.
