Parameter assignment
The force limit for the opening and closing direction can be set via the service menu with
General setup > Special parameters > Limit force open learn run
"
Special parameters > Limit force close learn run
The default value for the force limit in the opening direction during the learn run corresponds
to the high force limit in the opening direction.
The default value for the force limit in closing direction during the learn run is 150 N for AT40
and 230 N for ATD400V.
The higher effective force limit from the opening or closing direction is used to determine the
closed position.
Note
If a slightly too large door width is determined during the learn run, it can happen that after
the mains voltage is applied again, the active "initial mode" is not exited and the door always
runs at initial speed. In this case, the effective force during the learn run should be reduced.
If an obstruction occurs during the learn run (e.g. sluggish door), the effective force during
the learn run can be increased.
After changing the effective forces during the learn run, a "normal" learn run should be
performed.
During a learn run with default parameters, the effective forces during the learn run are reset
to the default values from the factory setting.
