Siemens SIDOOR ATD4 W Series - Automatic Impulsestop

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 326)).
Parameter assignment
The detection properties of ImpulseStop can be individually parameterized, thus enabling the
feature to be adapted to di󹪜erent door systems. The limit values for detecting an external
opposing force can be speci󹪝ed for each drive direction with the following parameters:
• p1240 in the opening direction
• p1241 in the closing direction
The parameters de󹪝ne 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.
4.3.4 Automatic ImpulseStop
Function description
The automatic ImpulseStop system is an extension of the automatic ImpulseDrive system. This
means that all the properties, con󹪝gurations and preconditions de󹪝ned for it are also applicable
here.
The system can be activated via the extension bit "ImpulseStop" (see Table A-17 DCMD
expansion bits (Page 320)), in connection with the automatic ImpulseDrive enable (see Table
A-16 DCMD signal (Page 319)).
If the "ImpulseStop" extension bit is active, the automatic ImpulseDrive system operates with the
slow driving pro󹪝le. The drive orders "slow open" and "slow close" are generated instead of
"open" and "close" respectively. The active drive order is canceled ("deenergized") as soon as the
ImpulseStop analysis/detection signals a corresponding opposing force (the rising signal edge is
decisive).
Note
The con󹪝guration of the ImpulseDrive analysis and detection directly a󹪜ects the automatic
ImpulseStop system.
Note
The automatic ImpulseStop system is a dynamic function. It can be enabled and disabled during
a door movement.
