Recording of measurement data
The recording of measurement data in the opening direction is divided into two subranges
because the door movement is not constant throughout the total range. The ranges are:
• Travel path ≤ 25 cm
– The measurement data in this range are recorded in the second opening movement and
after reaching the speed trigger level (learn run speed). As from this moment, the door
movement is almost constant. The measurement data are recorded every 2 cm, the rst
measured value is recorded 2 cm after the trigger level position (transient distance).
• Travel path > "End of weight determination"
– The measurement data in this range are recorded after the weight determination has
nished and the speed trigger level has been reached (learn run speed). As from this
moment, the door movement is almost constant. The measurement data are recorded
every 2 cm, the rst measured value is recorded 2 cm after the trigger level position
(transient distance).
The measurement data are recorded in the closing direction throughout the entire closing
movement within the learn run and after reaching the speed trigger level (learn run speed). As
from this moment, the door movement is almost constant. The measurement data are recorded
every 2 cm, the rst measured value is recorded 2 cm after the trigger level position (transient
distance). The measured values are recorded until the system reaches the "Cutter distance
CLOSE" range (p3663).
Calculations
1. The values "MEAN FRICTION FORCE OPEN/CLOSE [A]" and "STANDARD DEVIATION OPEN/
CLOSE [A]" in the "open" and "closed" positions are calculated on the basis of the
measurement data.
2. The values calculated in step 1 are converted to a force [N] with the aid of the motor
constants [N/A]
3. The force calculated in step 2 is added internally to the parameterized forces p3682, p3683,
p3684, and p3685
Note
The friction force is not taken into account in the parameterized torques p3679, p3680 and
p3681 (eective in the end stops) in order to avoid unnecessary heating of the motor.
Note
The corresponding internal force value, which is the result of the addition of the parameterized
force value and the calculated friction force, is limited to the maximum value of the respective
parameter.
4.2.6 Oscillation protection
The oscillation protection prevents permanent oscillation of the door at the end stop.
