SwitchOff: Switching-off position
SwitchOff*: corrected switching-off position
tOn: Switch-on anticipation

For cam_1 and _2
5.11.4.4 Note: No switching operation with overlapping cams
If it occurs that for example the switching-off position is smaller than the switching-
on position due to a movement caused by the reaction time compensation, no
switching will take place. This case must be eliminated by choosing appropriate
cam positions.

Pos_tOn: position difference calculated from the switch-on anticipation
Pos_tOff: position difference calculated from the switch-off anticipation
Please observe:
The position difference for the compensation of the switching delay rises with the
speed.
5.11.5. Hysteresis
In order to avoid jitter of cams at the limits of the switching area (only relevant as
source of cam with actual values) a switching hysteresis (the same for all cams)
can be defined.
