Position recognition of power windows, function - GF72.29-P-4000GH
MODEL 163 as of 1.9.01
Illustration of power ripples
Function
The evaluation of the window position is determined by the power ripples:
Each time the power window motor is readjusted it sends a pulse which is evaluated by the microcontroller integrated in the lower control panel control module (N72)
Each time the armature in the power window motor rotates the direction of the current changes 10 times and the position counter increases or decreases by "10".
When the permissible position ranges are exceeded, the power window motor is desychronized.
