Yes "Yes" means that a soft start with phase angle control or pulse
groups is performed after power ON.
Soft start type With phase angle
control This parameter only appears if soft start is set to "Yes."
Soft start type "With phase angle control" is available in the
phase angle control mode and in the burst-firing mode.
Phase angle control:
Starting from 180°, the phase control angle
α
is steadily re-
duced until the correct phase angle for the default setpoint
value is reached.
Burst-firing mode:
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.
