Determining the current position
Reference movement
The Blind/Roller Shutter Actuator continuously determines the current position of the blind and the slat
angle based on the duration of the individual movements. For various reasons, over extended periods
slight inaccuracies can occur in the determination of the position. Therefore, the Blind/Roller Shutter
Actuator uses the upper and lower end positions to unequivocally determine the current position of the
blind. Every time the blind is in the upper end position, the position is updated in the blind/shutter actuator
memory.
If the end positions are not reached in normal operation, a telegram can be used to trigger a reference
movement all the way up or down. After a reference movement, the blind remains in the reference position
or moves back to the stored position – whichever is specified in the parameters.
Direct and indirect movement to the position
The
Move to position
parameter determines whether a
Move to position
telegram moves the blind from its
current position either directly to the target position, or alternatively triggers a reference movement
indirectly via a start position (upper end position or lower end position) to a defined target position.
