ImpulseStop

Function description
The ImpulseStop analysis process detects and analyzes external forces acting on the door
system/drive system.
In conjunction with the automatic ImpulseStop system (see Section Automatic ImpulseStop
(Page 66)), a door can be stopped with a light tug against the direction of travel.
The process signals when an external opposing force (force with an opposite direction vector
to that of the door movement) acts on the door or the drive. It is signaled by the ASStp signal
(see Table A-33 ASStp signal (Page 296)).
Parameter assignment
The detection properties of ImpulseStop can be individually parameterized, thus enabling the
feature to be adapted to different door systems. The limit values for detecting an external
opposing force can be specified for each drive direction with the following parameters:
● p1240 in the opening direction
● p1241 in the closing direction
The parameters define a proportion of the learned reference value for each direction. This
proportion is added to the reference value, and thus forms the limit value for detecting
ImpulseStop.
