Automatic ImpulseStop

Function description
The automatic ImpulseStop system is an expansion of the automatic ImpulseDrive system.
This means that all the properties, configurations and preconditions defined for it are also
applicable here.
The system can be activated by the "ImpulseStop" expansion bit (see Table A-17 DCMD
expansion bits (Page 288)) in conjunction with automatic ImpulseDrive enabling (see Table
A-16 DCMD signal (Page 287)).
If the "ImpulseStop" expansion bit is active, the automatic ImpulseDrive system works in the
slow drive profile. 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
Configuring ImpulseDrive analysis and detection directly affects the automatic ImpulseStop
system.
Note
The automatic ImpulseStop is a dynamic function. It can be enabled and disabled during a
door movement.
