4.4.1 Driving to reference
The shutter actuator calculates its current positions from the set times for movement. Due to
external influences, over the time, slight displacements of the actual times for movement can occur.
A reference run recalculates the set times and thus provides the shutter actuator with new values for
the times for movement. Based on these new values, the actual position of the shutters/blinds can
then be calculated more precisely.
The driving to reference is especially useful if someone works very often with commands for absolute
positions. Therefore the shutter actuator can calculate the entered position more detailed and drive
to this position more precise. Every drive to the lowest or highest position replaces a driving to
reference. So the driving to reference should be done, when the shutter/blinds is only driven with
absolute commands lower than 100% and more than 0%. In this case, a reference drive should be
do e regularly, e.g. o e s a eek.
The reference run is started through an 1-

The "no reaction" setting keeps
the blind actuator in the position which was reached after completing the reference travel.
A reference run must be carried out after each transmission of a new parameterization. This can be
done either manually, i.e. the upper and lower end position is approached once or via the "Start
driving to reference" object. Only after a reference run has been carried out (via object up/down
or by the manual operation) the blind actuator knows its current status along the travel path.
4.4.2 Commands for absolute positions
By the objects for absolute positions you can specify a fixed value to the shutter actuator, on which
the shutter shall be driven. This value is indicated in percent and has a range from 0-100% with every
1% step between it. From the indicated percent value the shutter actuator calculates the real time
for the movement of the shutter/blinds based on the appointed times for movement and the actual
position.
The commands for the absolute position are transmitted to the 1 byte communication objects. There
is an object for the absolute height positions of the driving way at shutter and blinds. Additionally
there is a o je t for the ope i g a gle of the slats o ly at li ds , the o je t a solute positio of
slats
.
In the percent representation, 0% is always fully open and 100% completely closed.
