item Settings or if current
limiting has been set, increase
the current limiting value.
3. If the torque control is active,
check if the selected limiting
torque is high enough
(recommended ≥ 150 %)

The motor reaches its
nominal rotational
speed
- quicker than desired
- not softly
- if no current limiting
has been set according
to the specified ramp
time
The motor reaches
its nominal rota-
tional speed
- slower than
desired,
- not at all
(motor stuck)
The motor
- hums and does not
start immediately
- does not start at all
(motor stuck)

Quick commissioning of the
3RW44 SIRIUS soft starter
Wiring control
- Control part and
- Performance part
Check and connect the
voltages in the control and
main circuits.
Check set parameters in Settings > Parameter set > Motor.
Set starting and stopping parameters in Settings > Parameter
set > Starting or stopping settings according to the Table
"Suggested setting for commissioning" on the basis of the
respective application.
Start command "Soft starter on"

its nominal rotational
speed quickly and within
the desired time?

Quick commissioning menu, when switching on for the
first-time or after executing command "Factory settings"
Information on quick start menu
After supplying the control voltage for the first time, you will be
automatically directed to the quick start menu. You must
complete the entire quick start menu to commission the soft
starter.
If you confirm the last item "Save settings?" with "yes" in the
quick start menu, you can only return to this menu by resetting
the device back to the basic factory settting. (See manual or
operating instructions)
This overwrites all settings made up until that point.
Information on application selection:
Standard parameters are recommended on the basis of the set
type of application.
If the required load is not listed, choose a fan in order to
preselect the necessary start parameters.
In general:
The parameters are suggested settings.
The parameters may need to be optimized, as explained in the
Section "Start command "Soft starter on".
