Description
This parameter defines the maximum
dimming speed from 0 to 100%
For greater flexibility, 3 different values can
be specified.
(see below).
2nd pre-selectable dimming time.
3rd pre-selectable dimming time.
The change from 0% to 100% or 100% to
0% takes place within max. 1 s.
The change from 0% to 100% or 100% to
0% takes place within the preset dimming
time.
The change from 0% to 100% or 100% to
0% takes place within max. 1 s (in very
quick increments), but can be interrupted by
a stop command (release button).
The change from 0% to 100% or 100% to
0% takes place within the preset dimming
time in correspondingly lower increments.
The received dimming value is adopted
immediately (max. delay 1 s).
The change to the new dimming value takes
place within the preset dimming time,
proportionately to the change in value.
Example with dimming time 1 = 12 s:
Change from:
- 0 to 100% or 100 to 0% in 12 s (= 100%
of 12 s)
- 25 to 50% or 50 to 25% in 3 s (= 25% of
12 s)
etc.
The last dimming value before switching off
is saved and restored.
The configured minimum value is applied.
The dimmer adopts the selected value after
it is switched on.
Here again the configured minimum
dimming value needs to be taken into
account.
