4.1.9.1 Travel times
Fig. 29: Function diagram of travel times
The travel time is the time that the blind/shutter requires to move from the lower to the upper end posi-
tions (up) or from the upper to the lower end positions (down). Travel times for upward and downward
movements can be determined separately and set in ETS.
If the device receives a telegram to travel upwards or downwards, then the appropriate output is
switched and the blind/shutter moved in the required direction.
The blind/shutter is moved until the output receives a stop telegram or the end position is reached. The
limit switch switches the drive off when the upper or lower end position is reached. The corresponding
output contact remains closed until the parameterized travel time elapses.
If the travel time is extended by an overrun time (see parameter Disconnect output from power after),
the voltage will be switched off only after this overrun time expires.
If a value unequal to 100 % is set in the parameter Slat position after reaching lower end position (100 %
= disabled), the overrun time will not be taken into account. In this case, the output sets the slats ac-
cording to the parameterized value on reaching the lower end position.
4.1.9.1.1 Travel time determination
To determine the travel time, the travel times are measured from the lower to the upper end positions
and vice-versa, e.g. using a stopwatch. The measured values are then entered in the parameters Travel
time up and Travel time down.
The travel times are used to determine the current position of the blind/shutter during operation. The
travel times should therefore be measured and parameterized as accurately as possible.
For position movements, automatic control or status messages, precise travel times are the basis for ex-
act calculation and positioning of the blind/shutter.
