Movement Range Limits

For certain applications, e.g. in the case of open tilting windows or window boxes for flowers in the summer, it may be helpful or necessary to limit the possible movement range of a drive temporarily or permanently.

NOTICE
Blinds/roller shutters can be damaged. The blinds/roller shutters may move outside the movement range limits and into any open windows. For this reason, consider where the reference movement is to be made (Calibration). After a download or bus voltage recovery, a reference movement is made after initialization, even if the General reference movement function is disabled. The blinds/roller shutters may move outside the movement range limits and into any open windows. (Calibration). After a download or bus voltage recovery, the movement range limitation may be disabled because no activation telegram has been received. For this reason, consider where the reference movement is to be made: The reference movement after initialization is generally carried out towards the upper end position. A reference movement to the lower end position is only carried out if the parameter Reference position is set to lower. Functions with a higher priority, such as safety function or alarm function, can also control blinds/roller shutters outside the movement range limitation.

If movement range limitation is active, manual operation, automatic functions or scene calls can only move the drive within the defined limit. The limitation also applies to motion commands from functions a lower priority. Only a higher-level function with a higher priority can still be used to move the drive to a different position outside the limit. This must be taken into account if the movement range is to be limited due to an obstacle. Obstacles in operation must be avoided.

You can activate the limits of the movement range individually for each output channel (enabled).

Master / Ext. 1/2 Output 1+2 / 3+4 / 5+6 / 7+8 -Blind/roller shutter	Movement range limits
-Automatic, Locking & Calibration settings	Movement range limits	Disabled Enabled
	Limit movement range	Immediately after bus voltage recovery At object value "1" At object value "0"
	Feedback for range limitation	Disabled Enabled

After the function “Movement range limits” has been enabled, the parameter “Limit movement range” appears. Here you can define when and how the function is activated for the channel.

Immediately after bus voltage recovery: the function becomes active immediately after bus voltage recovery or after a download. The drive can only move between the limits. Only a function with a higher priority can move the drive to a position outside the limit.
At object value “1”: the object value “1” activates the limit. If the object value “0” is received, the entire movement range is enabled again.
At object value “0”: the object value “0” activates the limit.

A telegram with the object value “1” deactivates the limit. In the case of activation by an object value, an additional group object “Activate movement range limits”, which can be used to switch the limit on and off, appears for this channel.

You can set the limits of the movement range using other parameters:

	Master / Ext. 1/2 Output 1+2 / 3+4 / 5+6 / 7+8 -Blind/roller shutter	Movement range limits
	-Automatic, Locking & Calibration settings	Limit movement position	Limit range at upper position Limit range at lower position

If limitation is active, the drive will only move between the limits. The limitation applies to all motion commands from manual operation, automatic functions, scenes, and motion commands from functions with a lower priority. It is possible to limit either the upper position or the lower position.

Limit range at lower position with upper limit = 0% (fix) and lower limit = 25%

If limitation is active, the drive will only move between the limits.

If the drive is outside the limits when movement range limitation is activated, it is automatically moved to the nearest limit and stops there.

If a drive reaches its movement range limits, this can be signaled to the bus via a status feedback object. Functions that depend on it, e.g. opening a window, can now be executed.

Master / Ext. 1/2 Output 1+2 / 3+4 / 5+6 / 7+8 -Blind/roller shutter	Movement range limits
-Automatic, Locking & Calibration settings	Limit movement position	Limit range at lower position
	Limit movement position	Limit range at lower position
	Upper limit value in % (fix)	0
	Lower limit value in %	100 (0-100)
	Limit movement position	Limit range at upper position

	Upper limit value in %	100 (0-100)
	Lower limit in % (fix)	0

The movement range limitation function is often selected in summer when solar radiation is strong, so that it does not heat up rooms or dazzle people. The drive can no longer be moved manually all the way up, but in the event of a storm the weather alarm will move the blind to the safe position.
