5 Configuration
Soft start type
With phase angle
control
This parameter only appears if soft start is set to "Yes."
Starting from 180°, the phase control angle
α
is steadily re-
duced until a full wave has passed through.
This ends the soft start and a switchover to burst-firing mode
is performed.
Note: If the output level is reduced to 0 % for longer than 8
seconds, a soft start is initiated again as soon as the output
level is increased again.
If, during the soft start phase, current limiting is activated, the
soft start duration is extended because the phase control an-
gle cannot be reduced further during current limiting.
With pulse groups
This setting is only available in burst-firing operating mode
with a fixed cycle time and with the fastest possible cycle
time.
During the soft start time, the ON/OFF ratio is
increased from 0 to a maximum of 100 %.
Soft start duration
1 to 65535 s
Specifies the duration of the soft start.
Note:
Due to the system, when current limiting is switched on, the
soft start duration is at least 4 s, even if a shorter duration is
configured as the soft start duration.
Current limiting
No
No current limiting
Yes
The current limiting is implemented via phase angle control.
In this case, the load current is monitored on the basis of the
set current limit value.
Only the phase control angles that do cause the current limit
value to be exceeded are permitted.
It is also possible to activate an external current limit
value via a binary input.
