11.10 CLOSED LOOP JOYSTICK VEHICLE SPEED DEPENDENT CLOSED LOOP CONTROL
As each application is different, Danfoss has implemented a speed dependent closed loop control gain, configurable
for Closed Loop Joystick. When using a Closed Loop Joystick function, the PVED-
algorithm can vary the closed loop gain, dependent on the vehicle speed.
The range is from 0 to 100 kmph for P3728 to P3729 and from 0 to 200 [%] for P3725 to P3727.
These parameters represent the three points on the curve below (Point A, B and C). The Auto-guidance-algorithm will
make linear interpolation in between each of the three points. The operator is free to move the three points in any
direction, limited by the following rules:

Point A is always specified at Vehicle speed = 0 Kmph

B and

Point C
