Start-up
Disconnect output from power after
Options: End position, no overflow
End position + 2 % overflow
End position + 5 % overflow
End position + 10 % overflow
End position + 20 % overflow
Total travel time + 10 % overflow
After the end position has been reached (as the very top or bottom), the drive will switch off
independently. A so-called overflow travel time can be set to ensure that the output safely reaches
the end position. The voltage still remains applied for a short time to move the drive to a defined
end position in a controlled manner. The basis for the detection of the end position is the position
calculated internally in the device.
Enable communication object
"Trigger reference movement" 1 bit
Options: Yes
No
Reference movements are triggered using this communication object.

Yes: The communication object Trigger reference movement is enabled. Slight inaccuracies can
occur over longer periods in position detection due to temperature variants and aging
processes. For this reason, the upper and the lower end position can be used for clear
specification of the current position during position detection. Every time the blind/shutter is in
the upper or the lower end position, the position is updated in the memory of the device. If the
end positions are not reached in normal operation, a reference movement to the very top or
very bottom can be performed via a telegram. After a reference movement, the blind/shutter
remains in the reference position or moves back to the position before the reference movement,
according to the parameterization. The following parameter appears:
Position after reference movement
Options: No reaction, remain in reference position
Move to position before reference movement
This parameter defines how the output should respond after a reference movement.

No reaction, remain in reference position: The blind/shutter remains in the reference
position at the very top or very bottom.

Move to position before reference movement: The blind/shutter moves to the position it
had before the reference movement. During the reference movement, incoming STOP
or step telegrams are ignored and not executed after the reference position has been
reached. If automatic control was activated for the blind/shutter before the reference
movement, then this will be continued after the reference position has been reached.
Note
A reference movement is also triggered during active automatic control and interrupts
this for the duration of the reference movement.
After completion of the reference movement, the parameterized Position after reference
movement is executed first. When a new automatic telegram is received, the
blind/shutter moves to the automatic position.
