Parameter assignment

• Function con󹪝guration

Stop and force obstruction detection can be deactivated for each drive direction in parameter

p3850 (bits 0 and 1, and 4 and 5 respectively). In addition, counting of the obstructions can

be suppressed in accordance with the direction of travel (Bit 2 or 5).

• Lead times

After a drive order is changed or the direction of motion is reversed, the obstruction detection

is activated after a variable ON-delay time (p3852 and p3869).

• Range restriction

The obstruction detection is suppressed in a variable area before the respective end stop

is reached (p3856 or p3873).

It is also suppressed after leaving the relevant end stop (p3857 and p3874).

Force obstruction detection, in particular, is suppressed before the creep distance (p3858

and p3875). It is suppressed in a variable range after the last obstruction (p3859 and p3876).

If blocking of the door takes place in a tolerance range of 10 mm before the closed position,

this blocking is detected as a door end stop and the door controller switches to the "Closed"

state.

The tolerance range of 10 mm for the detection of the closed position is permanently stored

in the 󹪝rmware of the door controller and independently of the range de󹪝ned with the

parameters p3856 or p3873 for the obstruction detection.

To detect obstacles smaller than 10 mm before the closed position and trigger a blocking

reaction, e.g. reverse, the corresponding constructive measures have to be carried out at the

door. These can, for example, be rubber lips at the door edge or door pockets before the

closed position.

The tolerance range of 10 mm is necessary to consider mechanical changes of the door

mechanism. Changes can, for example, occur at the following components through

temperature or abrasion:

– Rubber bu󹪜er at the door edges

– Expansion und tension of the drive belt

– Contamination of the rail

– Modi󹪝cations to the door frame
