Automatic end point search / Brief explanation

22
To ensure smooth operation, solid (fixed, immovable) end points must be available for the
drive in both travel directions.
Automatic search run
The drive independently learns both end points.
IMPORTANT
Never try to simulate end points (e.g. by stopping the sliding unit with your hand or foot), as
these temporary end points would be lost after a power failure, for example, due to the
automatic synchronisation runs (see page 43).
Automatic reference run
Once the two end points have been found, the drive automatically carries out four reference
runs, in order to set the amount of force required to move the sliding unit, depending on the
specific conditions at the installation site.
The automatic reference run is a potential source of danger.
During the automatic reference runs the force limitation is not yet operational, therefore it is
important to ensure that no-one is in the path of travel of the sliding unit when these runs are
being performed.
NOTE
If the end point search is too sensitive, or not sensitive enough, this can be adjusted in menu
item (see page 26).
Manual adjustment of end points
During the end point search, the drive stops as soon as a control signal is sent during the automatic
end point search (e.g. from an external sensor or motion detector, or when the
pressed).
The following situations may occur which may lead to problems:
The current position of the sliding unit is then saved as an end point.
Automatic synchronisation after power failure is switched off.
The end stops may be lost after a power failure, should the position of the sliding unit
have changed (e.g. by pushing).
