Blind/Slat Settings - ABB i-bus KNX Product Manual

ABB i-bus® KNX FUNCTION
If the blind/shutter is moved to an end position by manual operation, this is evaluated as a reference
movement.
Stop commands do not trigger a reference movement.
4.1.9.4 Start-up and coasting delay and minimum run time
Some drives attain their full power only after a start-up delay of a few milliseconds or continue moving
for a few milliseconds after switch-off (coasting delay). For some applications, it is necessary to com-
pensate delay times during start-up and coasting of the drive, e.g. to position the blinds/shutters ex-
actly. The delay times can be set in the parameters Start-up delay and Coasting delay.
The minimum run time for the drive can be set in the parameter Minimum run time for drive.
If changes are made to these parameters in the user-defined setting, then the technical data of the re-
spective drive manufacturer must be observed.

Blind/slat settings

4.1.10.1 Direct and indirect movement to the position
The parameter Move to position can be used to define how the blind/shutter is to move to the target
position in response to a movement command.
• Direct: The blind/shutter is moved directly from its current position to the target position.
• Indirect: The blind/shutter is moved to the target position via the end position. It can be defined
whether the blind/shutter is to move to the target position via the upper, lower or closer end posi-
tion.
Indirect movement to the positions is used to position the blind/shutter. In order to maintain high posi-
tion accuracy, the position is updated in the device's memory when an end position is reached.
4.1.10.2 Move to position 0 % ... 100 %
The blind/shutter can be moved to any position via the group object Move to position height .
The percentages refer to the position of the blind/shutter between the upper and lower end positions.
• 0 %= upper end position
• 1 % ... 99 % = intermediate position
• 100 %= lower end position
In operating mode Blind/shutter control with slat adjustment , the slat can additionally be moved to any
position via the group object Move to position slat .
The percentages refer to the opening degree of the slats.
• 0 % = fully closed
• 1 % ... 99 % intermediate position
• 100 % = fully open
4.1.10.3 Blind/shutter control with slat adjustment
Two methods to control the slats and calculate the adjustment times can be selected in the parameter
Determine slat adjustment time:
• Via duration of slat adjustment (step)
• Via total duration for slat turning
