Description
Format
Value Range
Default
PWM Configuration and Overrides
ATDIM
R/W
Set dim level in percent
(0% off, 100% full
brightness)
DEZ
0
– 100
0
ATBLINK
R/W
Starts the light on a
low-high-low output
blink to allow
identification during a
commissioning or
maintenance process
DEZ
1: ON, 0: OFF
0
ATLOG
R/W
Set alternate dimming
curve (DALI
approximation)
DEZ
1: Logarithmic
0: Linear
0
ATRAMP
R/W
Set ramp time for
lighting adjustments in
percent. Time
configuration is used
for ATXPWM, ATDIM,
ATLED23M,
occupancy and Light
on/off
DEZ
0: No ramp used
1
– 100: Ramp time in percent (1s - 10s)
Example:
DIM 50%
– 0% with ATRAMP=50 takes
2.5 s
50
ATPWMFREQ
R/W
Set/Get the PWM
frequency in Hertz,
SYNC-Input is only at
886 Hz enabled
DEZ
100
– 4000 Hz
886
ATPWMx
R/W
Set PWMx Duty Cycle
target as an integer
percentage value
between 0 and 100,
removing it from any
control loop. Returns
always the current
configured PWM value
in perc
ent (x = 1 … 3)
DEZ
0
– 100
102 - Release PWM back into loop control
PWM1: 0
PWM2:
50
PWM3:
50
ATXPWMx
R/W
Set PWMx Duty Cycle
target as an integer
percentage value
between 0 and 100,
removing it from any
control loop. Returns
always the current
configured PWM value
in percent. Note: A
PWM in an XPWM
override mode will be
affected by the DIM pin
value when AUX is in
DIM mode. In AUX
mode it is also affected
by the AUX pin value.
(x = 1 .. 3)
DEZ
0
– 100
102 - Release PWM back into loop control
PWM1: 0
PWM2:
50
PWM3:
50
ATPWMOVR
R
Read the single 16-bit
sum of PWMs to
identify which have
been over-ridden and
removed from any
closed-loop control
loop
HEX
Bit0: ATXPWM1 active
Bit1: ATXPWM2 active
Bit2: ATXPWM3 active
Bit4: ATPWM1 active
Bit5: ATPWM2 active
Bit6: ATPWM3 active
