Safety instructions
This document contains instructions you are strongly advised to observe in order to guarantee your personal safety
and to avoid damage to property. The instructions on your personal safety are marked by a warning triangle, notes on
risk of property damage have no warning triangle. Depending on the degree of risk, the instructions are presented as
follows.
Danger
means that death or serious physical injuries will follow if you do not take the appropriate precautionary measures.
Warning
means that death or serious physical injuries may follow if you do not take the appropriate precautionary measures.
Caution
with a warning triangle means that minor physical injuries may follow if you do not take the appropriate
precautionary measures.
Caution
without a warning triangle means that damage to property may follow if you do not take the appropriate
precautionary measures.
Notice
means that an undesired result or condition may occur if the corresponding instruction is not observed.
Where several degrees of risk are present at the same time, the instruction for the highest degree of risk is used. If an
instruction with a warning triangle contains a warning against personal injury, the same instruction may also contain an
additional warning against damage to property.

Introduction
1.1
Physical Basics of the 3-phase Asynchronous Motor and Mode
of Operation of the Soft Starter
1.1.1 3-phase Asynchronous Motor
Applications of the 3phase asynchronous
motor
Thanks to their robust and simple design and low-maintenance operation, 3phase asynchronous motors are used in large numbers in commercial
applications, trade and industry.
Problem
If switched on directly, the typical current and torque behavior of the 3-phase
asynchronous motor may negatively influence the feeding supply network and
the load machine during start-up.
Starting current
3-phase asynchronous motors have a high direct starting current I(starting).
Depending on the motor version, this current may be 3 times to 15 times the size
of the rated operating current. A typical value is 7 to 8 times the size of the motor
rated current.
Disadvantage
This results in the following disadvantage
• Higher load on the electrical supply network. This means that the supply
network must be dimensioned for this higher output during motor start-up.

Figure 1-1:Typical starting current behavior of a 3-phase asynchronous motor
Start torque
The start torque and the stalling torque can usually be assumed to be between 2
and 4 times the rated torque. For the load machine, this means that the starting
and acceleration forces in relation to rated operation result in increased
mechanical load on the machine and the conveyed material.
Disadvantages
This results in the following disadvantages
• Higher load on mechanical parts of the machine
• Higher costs because of application wear and maintenance

Introduction
1.1.2 Operating Mode of the SIRIUS 3RW44 Electronic Soft Starter
The 3RW44 soft starter has two antiparallel thyristors in each of the phases.
There is one thyristor for the positive and one thyristor for the negative half
wave.
Using phase angle control and various control methods, the r.m.s. value of the
motor voltage is increased from a definable start voltage or start torque to the
motor rated voltage within a selectable starting time.
The motor current acts proportional to the voltage applied to the motor. Thus, the
starting current is reduced by the factor of the voltage that is applied to the
motor.
The torque behaves quadratically in relation to the voltage applied to the motor.
The starting torque is thus reduced quadratically based on the voltage applied to
the motor.

Introduction
Starting
This means that because the electronic soft starter controls the motor voltage
during motor start-up, it simultaneously controls the ingoing starting current and
the starting torque generated in the motor.
The same principle is also used during the stopping process. The effect is that
the torque generated in the motor is slowly reduced, thus enabling soft stopping
of the application.
During this process, the frequency remains constant and corresponds to the
network frequency, contrary to the frequency-controlled starting and stopping of
a frequency converter.
Upon completion of motor start-up, the thyristors are fully utilized, resulting in the
complete network voltage being applied to the motor terminals. Since no motor
voltage control is required during operation, the thyristors are bridged by
integrated bypass contacts. This reduces the waste heat developing during
continuous operation which is caused by power loss of the thyristor. Therefore,
the area around the switching devices heats up less.

Application and Use
Applications and
selection criteria
3RW44 soft starters are an alternative for star-delta starters and frequency
converters.
Their major benefits are smooth starting and stopping, uninterrupted changeover
without current peaks that would stress the power supply, and their compact
dimensions.
Numerous drives which previously could only be operated with frequency
converters can be changed over to soft starter operation using the 3RW44 soft
starter, as long as no speed control, no particularly high starting torque or no
startup with close to nominal current is required.

Configuration Instructions
2.1
Configuration
The electronic 3RW44 soft starters are designed for normal starting. A model
with a higher output may be necessary for heavy starting or for a higher starting
frequency.
A PTC thermistor in the motor is recommended for long starting times. This also
applies to the soft stop, pump stop and DC braking stopping modes, since there
is an additional current load in contrast to coasting down.
No capacitive elements (e.g. compensation systems) may be included in the
motor branch between the soft starter and the motor. Active filters must not be
operated in combination with soft starters.
All elements of the main circuit (such as fuses and switching devices) must be
dimensioned for direct starting according to the local short-circuit conditions and
should be ordered separately.
The harmonic load of the starting current must be taken into account when
selecting circuit breakers (release selection).
2.1.1 RS 232 Serial PC Interface and Soft Starter ES Parameterization and Operating Software
The electronic 3RW44 soft starters are equipped with a PC interface to
communicate with the Soft Starter ES smart software and an operating and
monitoring module (display).
2.1.2 Win Soft Starter Selection and Simulation Program
This software allows all SIEMENS soft starters to be simulated and selected
using various parameters such as network conditions, motor data, load data,
special application requirements, etc.
The software is a powerful tool which makes time-consuming and complex
manual calculations for determining the suitable soft starter a thing of the past.
The CD-ROM can be ordered using the following order number:
Order No.: E20001-D1020-P302-V2-7400.
2.1.3 Training Course for SIRIUS Soft Starters (SD-SIRIUSO)

2.2
Normal or Heavy Starting
To properly dimension a soft starter, it is important to know and take into account
the starting time (normal or heavy starting) of the application. Long starting times
mean a higher thermal load for the thyristors of the soft starter. The 3RW44 soft
starters are designed for continuous operation under normal starting conditions
(CLASS 10), an ambient temperature of 40 degrees Celsius and a fixed
switching frequency. You can also find these values in Chapter 10.3.2 "Technical
Data Power Unit". If deviations from these data occur, it may be necessary to
overdimension the soft starter. Using the Win Soft Starter selection and
simulation program from SIEMENS, you can enter your application data and
requirements, and it will determine the optimum soft starter dimensions for your
application (refer to Chapter 10.3.8 "Accessories" software).
Note
The adequate size of the SIRIUS 3RW44 soft starters must be selected on the
basis of the motor rated current
(Rated currentsoft starter ≥ motor rated current).

On-time and Switching Frequency
In terms of motor rated current and normal/heavy starting, the 3RW44 soft
starters are dimensioned for a maximum permissible switching frequency in
combination with a relative on-time. Please also refer to Chapter 10.3.2
"Technical Data Power Unit". If these values are exceeded, you may have to
select a larger soft starter.
On-time OT
The relative on-time OT in % corresponds to the relationship between the load
duration and the switching-cycle period of loads that are frequently switched on
and off.
The on-time OT can be calculated using the following formula:
ts + to
OT = ----------------------ts + to + ti

Installation Altitude and Ambient Temperature
The permissible installation altitude must not exceed 5,000 m above sea level
(above 5,000 m on request).
If the installation altitude exceeds 1,000 m, the rated operating current must be
reduced for thermal reasons.
If the installation altitude exceeds 2,000 m, the rated voltage must also be
reduced because of the limited insulation strength. For installation altitudes
between 2,000 m and 5,000 m above sea level, only rated voltages ≤ 460 V are
allowed.
The following illustration shows the reduction in the rated device current in
relation to the installation altitude:
The rated operating current Ie must be reduced when installed at 1,000 m above
sea level or higher.
Figure 2-2:Current reduction in relation to the installation altitude
Ambient temperature
The 3RW44 soft starters are designed to be operated with a nominal current at
an ambient temperature of 40 ° Celsius. If this temperature is exceeded,
e.g. due to excessive heating up in the switchgear cabinet, other loads or due to
a higher general ambient temperature, this will influence the performance of the
soft starter and must be taken into account in the dimensioning process (refer to
Chapter 10.3.2 "Technical Data Power Unit").

Warning
Automatic restart.
May result in death, serious injury or damage to property.
The automatic reset mode must not be used in applications where the
unexpected restart of the motor may lead to personal injury or
damage to property.
The start command (e.g. by the PLC) must be reset before a reset
command is issued, since an automatic restart is executed when a
start command is pending after the reset command is issued. This
especially applies to motor protection tripping. For safety reasons it is
recommended to integrate the group error output (terminals 95 and
96) into the control.
3.2.1 General
A motor branch consists of at least a disconnector, a switching element and a
motor.
Protection functions should include line protection against short circuits and
overload protection for line and motor.
Disconnector
The disconnecting function with line protection against overload and short
circuits can be achieved by using, for example, a circuit-breaker or a fuse
disconnector.
(For fuse and circuit-breaker assignment, refer to Chapter 10.3.6 "Branch
Component Circuitry (Standard or Inline Circuit)" and Chapter 10.3.7 "Branch
Component Layout (Inside Delta Circuit)".
Switching element
The 3RW44 soft starter provides the switching element function and motor
protection.
Danger
Dangerous voltage.
Danger to life or risk of serious injury.
If supply voltage is applied to the input terminals of the
soft starter, there may be dangerous voltages at the soft starter output
even without a start command! When working on the branch, it must
be disconnected using a disconnector (open isolating gap, e.g with
open switch disconnector)!

3.2.2 Soft Starters in Standard Circuits
The SIRIUS 3RW44 soft starter is connected in the motor branch between the
disconnector or circuit breaker and the motor.
The 3RW44 soft starter automatically detects the connection type of the soft
starter so this does not have to be explicitly set on the device. The detected
connection type can be read on the starter under the menu item "Status display/
Connection type". In this case, the
display reads "Star/delta". If the circuitry is faulty or the motor is not connected,
the display shows "Unknown".

Notice
If a main or line contactor is used, this contactor must not be connected
between the soft starter and the motor or in the return line between the motor
and the soft starter. Otherwise the soft starter would not recognize the current
circuit version (standard circuit or inside delta circuit) and would output the error
message: "Missing load phase 1-3", thereby ensuring that the circuit is closed
before the 3RW44 is activated.

typenschild.jpg
Figure 3-4:Name plate of a 22 kW motor
The SIRIUS 3RW44 soft starter can be dimensioned to match the current flowing
in the motor section (58 % of the conductor current) by connecting it in the delta
winding of the motor. This requires at least 6 motor lines.
The 3RW44 soft starter automatically detects how it is connected so the
connection type does not have to be explicitly set on the device. The detected
connection type can be read on the starter under the menu item "Status display/
Connection type". In this case the display reads "Inside delta circuit". If the
circuitry is faulty or the motor is not connected, the display shows "Unknown".
Notice
The rated motor current given on the name plate should always be set in the
quickstart menu or in the motor adjustment menu item. This setting is
independent of the type of connection of the soft starter.
Value to be set in the above example for a supply voltage of 400 V, e.g. 40.5 A.

Protection of the Soft Starter against Short Circuits
(Utilization class 2)
The soft starter has integrated thyristor protection against overloading. In the
event of a short circuit, e.g. due to a defect in the windings of the motor or a
short-circuit via the motor supply cables, this internal thyristor protection function
is not sufficient. Special semiconductor fuses, e.g. SITOR fuses from SIEMENS,
must be used for this purpose.
(Refer to Chapter 10.3 "Technical Data" for the fuse assignment)

Capacitors for Power Factor Improvement
Caution
Do not connect any capacitors to the output terminals of the soft
starter. If you do, the soft starter will be damaged.
Active filters, e.g. for reactive power compensation, must not be
operated in parallel while the motor control device is operational.
If capacitors for reactive power compensation are used, they must be connected
on the line side of the device. If a contactor disconnector or a main contactor is
used in combination with the electronic soft starter, the capacitors must be
disconnected from the soft starter when the contactor is open.

Device Interfaces
4.2.1 Local Device Interface
A local device interface on the front side of the starter is provided as standard.
This interface can be used to connect either an optional external operating and
display module, or the "Soft Starter ES smart" operating, monitoring and
parameterizing software (refer to Chapter 10.3.8 "Accessories" , Software) using
a PC and connecting cables.
4.2.2 Profibus Interface (Optional)
The SIRIUS 3RW44 soft starter can be equipped with an optional Profibus
module (only available for products delivered after 04/06). The soft starter can
be connected, operated and parameterized via the Profibus interface. The "Soft
Starter ES professional" operating, monitoring and parameterizing software
(refer to Chapter 10.3.8 "Accessories" , Software) can also be connected to this
interface using a PC and connecting cables.
Simultaneous operation of a 3RW44 with a Profibus interface is not possible in
networks where one phase conductor is grounded.
4.3
External Display and Control Unit (Optional)
When de-energized, the external display and control unit can be connected to
the local device interface via a special connecting cable.
After being switched on, the SIRIUS 3RW44 soft starter automatically recognizes
that the external display and control unit has been connected. The 3RW44
display will be inverted and the display of the display and control unit will be
showed in a normal way.
The control keys of the 3RW44 will be inactive so that normal handling is only
possible via the external display and control unit.

5.2.2 Quick Start Menu
Important
After applying the control supply voltage for the first time, you will automatically be in the
quick start menu which you must go through once to commission the soft starter for the
first time.
In the quick start menu you need to enter the information needed to preset the
most important parameters of the soft starter for your application. Starting
parameters for typical types of applications are stored in the device parameters.
To achieve an optimum motor start, these parameters may need to be optimized
on the basis of the connected load using the "Settings" menu item, as described
in Chapter 5.4.3 "Specifying the Starting Mode".
If your particular load is not listed, select any load and optimize the defined
parameters using the "Settings" menu item as described in Chapter 5.4.3
"Specifying the Starting Mode".
The factory setting values of the parameters and the predefined assignment of
the control inputs and outputs are listed in Chapter 10.3 "Technical Data".
Important
If you confirm the last item "Save settings - execute?" with "Yes" in the quick start menu,
you can only return to this menu by resetting the device back to the factory settings (refer
to "Restoring the factory settings" on Page5-40.). This overwrites all settings made up
until that point.

The setting is buffered in a Flash E-Prom memory as soon as you change a setting in the
menu and execute it using the "OK" button. It is then active in the soft starter from this
moment onwards. When the control supply voltage is switched off, this value will be
canceled and the previous value restored. In order to permanently save the settings made
in the soft starter, you must save the data as described in Chapter 5.3.1 "Main Menu Item

Notice
Always set the rated operating current of the motor stated on the motor name plate for the
prevailing supply voltage. This setting is independent of the connection method of the soft
starter (soft starter in standard or inside delta circuit). Value to be set in the above
example for a supply voltage of 400 V, e.g. 40.5 A.
The motor current of the connected drive should be set to ensure proper functioning of the
soft starter during starting and stopping as well as in regard to motor protection.

Rated torque
If the rated torque of the motor is not indicated on the name plate, it can be
calculated using the following formula:
1000
M = 9.55 × P × ------------n
Example
1000 9.55 × 22 kW × ---------------------------= 143 Nm
–1
1470 min
If no value is specified, the value of the factory setting is active (0 Nm).
When the start command is given and the motor is connected, the required value
is automatically calculated once by the soft starter.
Notice
If a motor is connected to the soft starter (e.g. for testing purposes) whose rated data
(current, speed, torque) differs from the values already entered, these rated data must be
adapted to the new motor. If 0 Nm is entered as the rated torque, the value is
automatically calculated once by the soft starter.

Explanation of the possible parameters:
1)
No action:
Input without function.
2)
Manual operation local:
When operated with Profibus, the soft starter control can be
transmitted to the inputs by activating the input control. The
control functions via Profibus are deactivated during this time.
3)
Emergency start:
Error: Current unbalance exceeded, thermal motor model
overload, temperature sensor open, temperature sensor short,
temperature sensor overload, maximum starting time exceeded,
current limit exceeded/undershot, ground fault, impermissable le
/ class setting: In the case of these faults, the motor can be
started via the emergency start function despite a pending group
error input. An emergency start action will be assigned to one
input, "Motor right > parameter set 1" e.g. assigned to another.
The emergency start is active as long as the input is activated. It
can also be activated during operation.
4)
Slow speed:
The motor starts with the values set under the "Slow speed
parameters" menu item when the "Slow speed" input and the
"Motor right/left parameter set 1/2/3" input are activated at the
same time.
5) Quick stop:
If the input is activated, an operational tripping with the currently
set stopping function is carried out (no group error appears).
The quick stop is carried out independently of the control priority.
6)
Trip reset:
Pending faults can be acknowledged after rectification.
7)
Motor right parameter set 1/2/3:
The motor starts (with rotation in line phase direction) and stops
with the values stored in the respective parameter set.
8)
Motor left parameter set 1/2/3:
This function is active only when the Sslow speed" parameter is
active at the same time. The motor starts with the values stored
under the "Slow speed parameters" menu item (with rotation
counter-clockwise to the line phase direction).

Notice
In the case of heavy starting and set values of the tripping class ≥ CLASS 20, we recommend setting the "Prewarning
limit tripping reserve" parameter value to 0 s (deactivated) and increasing the parameter "Prewarning motor
temperature" to 95 % Otherwise, a warning message regarding motor protection will be issued when starting.
Notice
If CLASS settings other than 5(10a) or 10 are selected, it may be necessary to check and adjust the set values for the
rated operating current Ie of the motor (Chapter 5.4.2 "Entering the Motor Data") in all 3 parameter sets, since otherwise
the error message "Impermissible Ie/ CLASS settings" may be issued.
For the maximum permissible set value for the rated operating current Ie of the motor in regard to the CLASS settings
please refer to Chapter 10.3.2 "Technical Data Power Unit".

Notice
Use of the 3RW44 to operate motors in hazardous areas:
The 3RW44 does not have an ATEX certificate. When an ATEX certified overload relay is
used (e.g. 3RB2 from Siemens), which affects an additional device (e.g. contactor), the
3RW44 can be installed in series to this overload relay so that the ATEX requirements are
met.
Important
The internal motor overload protection of the SIRIUS 3RW44 soft starter must be
deactivated for this kind of installation! (Set value under the menu item Motor protection/
Tripping class: "None" and Motor protection/Temperature sensor: "Deactivated")

Note
When using the 3RW44 soft starter in an IT system with ground fault
monitoring: 3RW44, product version ≤ *E06* and the PROFIBUS DP
communication module may not be used in this network configuration.
3RW44 soft starters as of product version *E07* can be used in
combination with the PROFIBUS DP communication module. However,
the phase voltage values (UL-N) and phase-to-phase voltage values (ULL) may be displayed incorrectly on the measurement-value display of the

circuit type, the currents measured internally by the soft starter are
extrapolated to the supply cable current (phase current) by a factor of 1.73
and displayed.
Due to asymmetries, the phase currents in the inside delta circuit may

Various Parameter Sets
The soft starter provides three individually adjustable parameter sets. One
starting mode and stopping mode can be directly specified per parameter set.
Applications
• Starting Dahlander motors (variable-speed drive).
• Starting an application with different load conditions (e.g. empty or full
conveyor belt).
• Separate starting of up to three drives with different run-up behavior
(e.g. compressor and pump).

GWA 4NEB 535 2195-02 DS 04
Device Functions
6.2
Starting Modes
Different starting functions can be selected thanks to the large number of
applications for which the SIRIUS 3RW44 soft starter can be used. The motor
start can be set optimally according to application and deployment.
6.2.1 Voltage Ramp
The simplest type of soft start with the SIRIUS 3RW44 is achieved using a
voltage ramp. The terminal voltage of the motor is increased from a
parameterizable start voltage to line voltage within an adjustable starting time.
This starting mode is preset in the quick start menu.
Start voltage
The level of the start voltage determines the switch-on torque of the motor. A
smaller start voltage results in a smaller start torque and smaller starting current.
The start voltage should be high enough so that the motor starts immediately
and softly when the start command is sent to the soft starter.
Starting time
The length of the starting time determines the time in which the motor voltage is
increased from the set start voltage to the line voltage. This influences the
acceleration torque of the motor, which drives the load during the run-up
procedure. A longer starting time results in a smaller acceleration torque over
the motor run-up. This results in a longer and softer motor run-up. The length of
the starting time should be selected such that the motor reaches its nominal
speed within this time. If this time is too short, i.e. if the starting time ends before
the motor has run up, an extremely high starting current will occur at that
moment, reaching the value of the direct starting current at this speed. The soft
starter can, in this case, switch itself off via the internal overload protection
function and go into fault mode.
Maximum starting
time
The "Maximum starting time" parameter is used to determine the time after which
the drive should have fully run up. If the drive is not in nominal operation upon
completion of the set time, the starting procedure is aborted and an error
message is generated.
Internal run-up
recognition
The soft starter features an internal run-up recognition. If a completed motor runup is recognized by the device, the internal bypass contacts will close and the
thyristors are bridged. If this run-up recognition is performed before the set runup time is completed, the ramp is aborted and the motor voltage is immediately
increased to 100 % of the line voltage before the internal bypass contacts are
closed.

Typical applications for voltage ramps
The voltage ramp function principle is suitable for any type of application.
If test runs are carried out using motors that are smaller than those used in
actual applications, we recommend using the "Voltage ramp" starting mode.
For machines requiring a breakaway pulse (inverse load response, e.g. in mills
or crushers), the breakaway pulse must be set as described in Chapter 6.2.3
"Breakaway Pulse in Combination with the Voltage Ramp or Torque Control
Starting Mode". The "voltage ramp+current limiting (U+current limiting)" starting
mode is recommended for heavy starting.

6.2.2 Torque Control
The motor speed and torque is calculated using the voltage and current r.m.s.
values as well as the associated phase information between the line voltage and
the motor current (= cos ϕ = sensorless control) and the motor voltage is
controlled accordingly.
Torque control means that the torque generated in the motor is linearly increased
from a parameterizable start torque up to a parameterizable end torque within an
adjustable starting time.
The advantage over the voltage ramp is improved mechanical run-up behavior of
the machine.
The soft starter controls the torque generated at the motor continuously and
linearly according to the set parameters until the motor has completely run up.
For optimum torque control during the stopping process, the motor data of the
motor connected to the soft starter should be entered in the selected parameter.
This can be specified using the "Setting" menu item.
Start torque
The height of the start torque determines the switch-on torque of the motor. A
smaller start torque results in a smaller run-up torque and smaller starting
current. The start torque should be high enough so that the motor starts
immediately and softly when the start command is sent to the soft starter.
Limiting torque
The level of the limiting torque determines which maximum torque should be
generated in the motor during running up. This value can thus also act as an
adjustable torque limitation.
In order to obtain a successful run-up, the parameter value should be set to
about 150 %. It should be at least high enough so that the motor does not get
stuck during startup. This ensures that enough acceleration torque is generated
throughout the entire motor run-up phase.
Starting time
The length of the starting time determines the time in which the start torque is
increased to the end torque.
A longer starting time results in a smaller acceleration torque over the motor runup. This results in a longer and softer motor run-up. The length of the starting
time should be selected such that the motor accelerates softly until it reaches its
nominal speed.
If the starting time ends before the motor has completely run up, the torque is
limited to the set limiting torque until the soft starter recognizes the run-up
process and closes the internal bypass contacts.
Maximum starting
time
The "Maximum starting time" parameter is used to determine the time after which
the drive should have fully run up. If the drive is not in nominal operation upon
completion of the set time, the starting procedure is aborted and an error
message is generated.
Internal run-up
recognition
The soft starter features an internal run-up recognition. If a completed motor runup is recognized within the defined starting time, the ramp will be aborted and
the motor voltage will immediately be increased to 100 % of the line voltage. The
internal bypass contacts will close and the thyristors are bridged.

Typical applications for torque control
Torque control is suitable for all applications, especially in cases where a
homogeneous and smooth run-up is required. For machines requiring a
breakaway pulse (inverse load response, e.g. in mills or crushers), the
breakaway pulse must be set as described in Chapter 6.2.3 "Breakaway Pulse in
Combination with the Voltage Ramp or Torque Control Starting Mode". The
"Torque control+current limiting (M+current limiting)" starting mode is
recommended for heavy starting (refer to Chapter 6.2.4 "Current Limiting in
Combination with the Voltage Ramp or Torque Control Starting Mode").

6.2.3 Breakaway Pulse in Combination with the Voltage Ramp or Torque Control Starting Mode
This function is required for load machines with inverse torque behavior. Typical
applications are mills, crushers or drives with plain bearings. In such cases it
may be necessary to create a breakaway pulse at the beginning of the machine's
start process. The breakaway pulse is set via the breakaway voltage and the
breakaway time. Using the breakaway pulse, the high limiting friction of the load
can be overcome and the machine can be set into motion.
The breakaway pulse can be used in combination with the voltage ramp, torque
control or current limiting starting modes and is superimposed on these during
the whole breakaway time.
Breakaway voltage
The breakaway voltage setting determines the breakaway torque to be
generated. Its maximum value can be 100 % of the start torque generated on
direct starting. The pulse should be high enough for the motor to start
immediately when the soft starter receives the start command.
Breakaway time
The breakaway time specifies how long the breakaway voltage should be
applied. Upon completion of the breakaway time, the soft starter finishes its runup process with the selected starting mode, e.g. voltage ramp or torque control.
The selected breakaway time should be at least long enough so that, after the
configured time has elapsed, the motor does not remain stationary again but
rather accelerates further in the selected starting mode.
If 0 ms is set as the breakaway time (default), the breakaway pulse function is
deactivated.

Typical applications for breakaway pulses
Typical applications for breakaway pulses are load machines with inverse torque
behavior, e.g. crushers and mills.
Note
A breakaway pulse that is too high may lead to the error message "Current
measurement range exceeded".
Remedy: Use larger starter dimensions or a lower breakaway voltage.
Only set the breakaway pulse when it is really required (e.g. for mills for
crushers).
A wrongly set breakaway pulse, e.g. for pumps, may lead to the error message
"Incorrect start conditions".

6.2.4 Current Limiting in Combination with the Voltage Ramp or Torque Control Starting Mode
The starter continuously measures the phase current (motor current) using the
integrated current transformer.
During motor run-up it is possible to set a current limit value on the soft starter.
The current limiting can be activated if "Voltage ramp+currrent limiting" or
"Torque control+current limiting" have been selected as starting mode and a
value has been entered in the relevant parameter.
During the starting procedure, the phase current is limited to the set value until it
falls below this value. A defined breakaway pulse is superimposed on the current
limiting during the breakaway time.
Current limit value
As a factor of the motor rated current, the current limit value is set to the
maximum current required during the starting procedure. If the set current limit
value is reached, the motor voltage is lowered (or controlled) by the soft starter
such that the current will not exceed the set current limit value. The configured
current limit value must be selected high enough that enough torque can be
created in the motor in order to bring the drive into the rated area of operation. A
typical value is 3-4 times the value of the rated operating current (Ie) of the
motor.
Run-up recognition
The soft starter features an internal run-up recognition. If a completed motor runup is recognized, the motor voltage is immediately increased to 100 % of the line
voltage. The internal bypass contacts will close and the thyristors are bridged.

Device Functions
6.2.5 Starting Mode: Direct On-line
If the "Direct on-line" starting mode is set, the motor voltage is immediately
increased to line voltage when it receives the start command. This resembles the
starting behavior with a contactor, i.e. the starting current and start torque are
not limited.
Note
Due to the high starting current of the motor, the error "Current limit exceeded"
may occur in direct on-line starting mode. It may be necessary to select a larger
dimensioned soft starter.
Run-up recognition
The soft starter features an internal run-up recognition. If a completed motor runup is recognized, the internal bypass contacts will close and the thyristors are
bridged.
6.2.6 Starting Mode: Motor Heating
If IP54 motors are used outdoors, condensation occurs in the motor during
cooler periods (e.g. overnight or in the winter). This may lead to leakage currents
or short circuits when the devices are switched on.
A pulsating DC current is fed into the motor winding to warm it up.
If the "Motor heating" starting mode is selected, a heating capacity can be
entered in the settings. This capacity should be chosen in such a way that the
motor will not be damaged. The setting range for the heating capacity extends
from 10 - 100 %. This corresponds to a motor current of approximately 5 - 30 %
of the motor rated current.
Typical applications for motor heating
Used e.g. in outdoor drives to minimize condensation inside the motor.
Caution
May lead to damage to property.
The motor heating starting mode is not a continuous operating mode. The motor
must be equipped with a temperature sensor (Thermoclick/PTC) to ensure motor
protection. The motor model with integrated electronic motor overload protection
is not suitable for this kind of operation.

6.3
Stopping Modes
Different stopping functions can be selected thanks to the large numbers of
applications for which the SIRIUS 3RW44 soft starter can be used. The motor
stop can be set optimally according to application and deployment.
If a start command is output while the motor is being stopped, this process is

Note
If guided stopping is selected as stopping mode (soft stop, pump stop or
braking), it may be necessary to select a larger dimensioned branch (soft starter,
wiring, branch protection elements and motor), since the current exceeds the
motor rated current while the motor is being stopped.

6.3.1 Coasting Down
Coasting down means that when the on command to the soft starter is removed,
the energy feed to the motor via the soft starter is interrupted. The motor will
coast down freely, only driven by the mass reactance (centrifugal mass) of the
rotor and the load. This is designated as a natural run-down. A larger centrifugal
mass means a longer coasting-down.
Typical applications for coasting down
Coasting down is used for loads with no special requirements in terms of
stopping behavior, e.g. large fans.

6.3.2 Torque Control and Pump Stop
In "Torque-controlled" and "Pump stop" mode, the coasting down process/
natural run-down of the load is extended. This function is set if abrupt stopping of
the load is to be prevented. This is typical in applications with small mass
reactances or high counter torques.
For optimum torque control during the stopping process, the motor data of the
motor connected to the soft starter should be entered in the selected parameter
set. This can be specified using the "Setting" menu item.
Stopping time and
stopping torque
The "Stopping time" parameter of the soft starter can be used to specify for how
long power should be fed into the motor after removal of the switch-on
command. Within this stopping time, the torque generated in the motor is
continuously and linearly reduced to the set stopping torque and the application
is smoothly stopped.
Pump stop
In pump applications, so-called water hammers may occur if the drive is stopped
abruptly without using pump stop. These water hammers are caused by the
sudden break in the flow and the accompanying pressure deviations in the
pump. They cause noise
and a mechanical impact on the piping as well as on the flaps and valves inside
the system.

6.3.3 DC Braking / Combined Braking
In DC braking or combined braking, the coasting down / natural run-down of the
load is shortened.
The soft starter imposes a (pulsating) DC current in phases L1 and L3 on the
motor stator. This current creates a permanent magnetic field in the stator. Since
the rotor is still rotating due to its mass reactance, currents are induced into the
short rotor winding, creating a braking torque.
Notice
The DC braking / combined braking stopping function is not possible in an inside
delta circuit.
Note
The pulsating DC current loads the network asymmetrically and the motor and
the branch must be dimensioned accordingly for the higher current load during
the stopping procedure. A larger dimensioned soft starter may be necessary.
Note
Two braking versions are available:
Combined braking:
Use the combined braking function if applications with small mass reactances
(centrifugal masses) are to be stopped
(JLoad ≤ JMotor). The real stopping time can vary during braking processes when
the combined braking function is applied. Use the function DC braking if a
consistently long braking time is to be achieved.
DC braking:
Use the DC braking function if applications with larger mass reactances
(centrifugal masses) are to be stopped
(JLoad ≤ 5 x JMotor).
An external brake contactor is required for the DC braking function!
Caution
Risk of damage to property.
A combination of electronic motor overload protection and evaluation of a
temperature sensor integrated into the motor is recommended for optimum
motor protection.
Stopping mode: combined braking
If combined braking is selected, the dynamic braking torque, DC braking torque
and stopping time parameters can be configured on the starter.
Dynamic braking
torque
The dynamic braking torque determines the extent of the braking effect at the
start of the braking process in order to reduce the rotational speed of the motor.
The braking process is then continued using the DC braking torque function.
DC braking torque
The height of the DC braking torque determines the brake force of the motor.
If the motor accelerates again during DC braking, the dynamic braking torque
must be increased.

Device Functions
Stopping time
The stopping time determines how long braking torque is applied to the motor.
The braking time should be long enough to bring the load to a complete
standstill.
To achieve a sufficient brake effect until standstill, the centrifugal mass (J) of the
load should not exceed that of the motor. The stopping time should be selected
such that the motor comes to a standstill. The soft starter has no standstill
recognition; if required, this must be accomplished using external measures.

If the DC braking function is selected, the stopping time and DC braking torque
parameters can be configured on the starter. With this braking type, one output
of the soft starter must be switched over to DC braking to control an external

Slow Speed Function
This function allows an asynchronous motor to be temporarily operated in both
directions at a rotational speed that is lower than the rated rotational speed.
The rated rotational speed nmotor of the motor is determined by its line frequency
(f) and its number of pole pairs (p).
60
n Motor = f × -----p
A resulting slow speed frequency for the motor is defined by a specific thyristor
control. However, this function requires that only a reduced torque can be
generated in the motor. Due to possible overheating of the motor, this function is
not suitable for continuous operation.
The slow speed factor and the slow torque can be entered individually for both
directions of rotation.
Slow speed factor
By adjusting the slow speed factor, it is possible to control the motor with a
rotational speed (n Slow speed) that is lower than the rated rotational speed either
in the same or opposite direction of rotation to that of the line.
n Rated
n Slow speed = ---------------------------------------------Slow speed factor
Slow torque
The torque generated in the motor can be influenced using the slow torque. The
maximum torque which can be created depends on the slow torque that is
specified. 100 % slow torque can correspond to approx 30 % of the motor rated
torque.
Line frequency
Resulting "slow speed frequency"
Figure 6-10:Slow speed function
Typical applications for slow speed function
This function is suitable for applications with a low counter torque, e.g. when
machine tools are positioned.
Note
In addition to the set parameters, the motor-specific properties and the
connected load also affect the rotational speed resulting from the slow speed
function and the slow torque generated in the motor.

Note
To control the motor with the specified slow speed parameters, "Slow speed"
must be assigned to one control input, and "Motor right PS1/2/3" or "Motor left
PS1/2/3" must be assigned to the other. Also refer to the circuit proposal in
Chapter 8.1.7.
Directions of rotation:
Right: rotation in line phase direction
Left: rotation counter-clockwise to the line phase direction
Notice
Due to the reduced motor speed and the accompanying reduced self-cooling of
the motor this operating mode is not recommended for continuous operation.
Caution
Risk of damage to property.
For optimum motor protection use a combination of electronic motor overload

It is possible to set maximum and minimum current limits; if these limits are
exceeded or undershot, a message can be output.
Minimum current

The minimum current limit can, for example, be used to indicate a V-belt break
and the corresponding no-load current of the motor or that the fan filter is
clogged.

The maximum limit value can be used to determine increased power loss in the
application, e.g. caused by storage damage.

Motor Protection Functions
The motor overload protection is based on the motor winding temperature. This
temperature is used to determine whether the motor is overloaded or is
operating within its normal rating.
The winding temperature can either be calculated using the integrated
electronic motor overload function, or be measured using a connected motor
thermistor.
Both versions must be combined (=activated) to obtain the so-called full motor
protection. This combination is recommended for optimum motor protection.
Motor overload
protection
The current flow during motor operation is measured using current measurement
at the converters in the soft starter. The temperature rise of the winding is
calculated on the basis of the configured rated operating current of the motor.
Depending on the set tripping class (CLASS setting) and protection parameters,
a warning or a trip is generated when the characteristic curve is reached.
SIRIUS 3RW44 System Manual
GWA 4NEB 535 2195-02 DS 04

Device Functions
Tripping class
(electronic overload
protection)
The tripping class (CLASS) indicates the maximum tripping time in which a
protective device must trip at a value 7.2 times that of the rated operating current
in cold condition (motor protection acc. to IEC 60947). The tripping
characteristics indicate the tripping time in relation to the tripping current (refer
to Chapter 10.4 "Tripping Characteristics").
Different CLASS characteristics are available for normal or heavy starting.
Note
The rated data of the soft starters are based on normal starting (CLASS 10). For
heavy starting (> CLASS 10) it may be necessary
to select a larger dimensioned soft starter.
Current asymmetry
limit value
Three-phase asynchronous motors respond to slight line voltage asymmetries
with a higher asymmetrical current consumption. This increases the temperature
in the stator and rotor winding.
The asymmetric limit value is a percent value by which the motor current may
deviate in the individual phases.
The reference value for the evaluation is the maximum deviation from the
average value of the three phases.
Asymmetry is defined as a deviation of more than 40 % from the average value.
Prewarning limit
tripping reserve
If the set prewarning time limit is reached, which is based on the calculated time
until the motor is stopped by the motor protection function, a message can be
output.
Prewarning limit
motor heat build-up
A message can be generated if the configured thermal prewarning limit of the
motor is reached. Tripping of the motor protection occurs at 100 %.
Idle time
The idle time is a setpoint time for the cooling behavior of the motor model after
a normal shutdown, i.e. not after overload trips.
After this period, the "Thermal motor model" of the motor starter is set to 50 % if
the motor heat build-up is still at > 50 %, otherwise it is set to 0 %.
This enables frequent start procedures (inching). Depending on the CLASS
settings, these frequent start procedures lead to tripping where motor protection
acc. to IEC 60947 is used.

Caution
Risk of damage to property.
If the idle time is changed (0 = deactivated), motor protection acc. to IEC 60947
(CLASS 10A, 10, 15, 20, 30) is no longer ensured. This means that there will be
no system protection in such cases. We recommend protection action to be
taken in parallel.
Caution
Risk of damage to property.
The motor must be designed for such inching operation, otherwise the overload
may cause permanent damage.
Pre-charge time
When the thermal motor model is tripped, a pre-charge time is started to let the
motor cool down and to prevent the motor from being restarted before the precharge time has elapsed.
Protection against
voltage failure
If protection against voltage failure is active and the control supply voltage
breaks down while a trip is pending, the current trip condition of the thermal
motor model and the current pre-charge time are stored in the soft starter. When
the control supply voltage returns, the trip condition of the thermal motor model
before voltage failure will be restored.

Temperature sensor
The temperature sensor motor protection function measures the motor's stator
winding temperature directly using a measuring sensor in the motor, i.e. this
requires a motor with a measuring sensor wound into the stator winding.
Two different types of measuring sensors are available for the evaluation.
• PTC thermistors type A ("type A sensors")
• Thermoclick
The wiring and the sensors are checked for wire breaks or short circuits.
Notice
If the soft starter is switched off via a motor protection or device protection
tripping, the action cannot be acknowledged using the "Trip reset" function until
the displayed cooling time has expired.

Inherent Protection
The soft starter has integrated device protection to prevent the thyristors from
becoming thermally overloaded.
This is achieved via current measurement using converters in the three phases
and by measuring the temperature with thermosensors at the thyristor heatsink.
If a fixed warning threshold is exceeded, a message is issued by the soft starter.
If the fixed tripping value is exceeded, the soft starter switches off automatically.
After a trip has occurred, a fixed 30-second pre-charge time must be kept before
the starter can be restarted.
If protection against voltage failure is active and the control supply voltage
breaks down while a trip is pending, the current trip condition of the thermal
motor model and the current pre-charge time are stored in the soft starter. When
the control supply voltage returns, the trip condition of the thermal inherent
protection before voltage failure will be restored.
In order to protect the thyristors from being destroyed by short circuits (e.g. in
the event of cable damage or a shorted coil in the motor), SITOR semiconductor
fuses must be connected upstream. You can find the corresponding selection
tables in Chapter 10.3.6 "Branch Component Circuitry (Standard or Inline
Circuit)" and in Chapter 10.3.7 "Branch Component Layout (Inside Delta
Circuit)".
Notice
If the soft starter is switched off via a motor protection or device protection
tripping, the action cannot be acknowledged using the "Trip reset" function until
the displayed cooling time has expired.

The set rated operating current Is of the motor (Chapter 5.4.2 "Entering the Motor Data")
exceeds in at least one of the three parameter sets the corresponding, maximum
permissible set current, based upon the selected CLASS settings (Chapter 5.4.9
"Selecting Motor Protection Settings"). In product version ≥ *E07* devices, the
corresponding parameter set (PS) in which the incorrect value is to be found will be
displayed.
For maximum permissible adjustable values please refer to Chapter 10.3 "Technical Data".
If the soft starter is connected in an inside delta circuit, the motor feeder may have been
incorrectly wired (Chapter 9.1.5 "3RW44 in an Inside elta Circuit") so that the "Status
display / Connection method" menu item (Chapter 5.5.2 "Status Display") shows
"Unknown / fault".
Remedy: Check the set rated operating current of the motor in all 3 parameter sets,
reduce the CLASS setting or use larger soft starter dimensions. If used for inside delta
circuits, check the wiring of the motor feeder to ensure that it corresponds to the specified
circuit diagrams.
If the motor is not activated this is only a status message. However, the message turns into
an error without restart once a start command is issued.
No external start parameters received
(for product version ≥ *E06* devices)

Statistics data for device service life
• Operating hours
The soft starter records 2 operating hour values:
– The motor operating hours.
These indicate how long the motor has been switched on.
– The device operating hours (soft starter).
These indicate how long the 115 V AC or the 230 V AC supply voltage of the
soft starter has been switched on.
Both operating voltage values are recorded in data set 95 - "Read statistics".
They are recorded in the "Operating hours" data field once every second.
The operating hours are recorded in the range of 0 to 232 seconds in
1-second increments.
• Number of overload trips
The soft starter counts the number of overload trips in the 0 to 65 535 range.
• Number of starts motor right / left
The soft starter counts the number of starts in the 0 to 232 range.
Example: The value is incremented by 1 when current is flowing in the main
circuit following a "Motor ON" command.
• Number of starts outputs 1 to 4
• Motor current Imax.
The soft starter measures the current in all 3 phases and indicates the current
of the phase with the highest load as a percentage [%] of the set current Ie.
Data format: 1 byte, 8-bit current format
Example: Set current I e = 60 A
Indicated motor current 110 %
corresponds to 60 A x 1.1 = 66 A
All 3-phase currents are available in data set 94
• Last trigger current
The soft starter measures the current in all 3 phases and indicates the current
flowing through the phase with the highest load at the time of the tripping as a
percentage [%] of the set current Ie and in amperes [A]
Data format: 2 byte, 9-bit current format
Example: Set current I e = 60 A
indicated motor current 455 % corresponds to 60 A x 4.55 = 273 A

1) For permissible values for main and control voltage, refer to Technical Data, Pages 10-8 to 10-12.
2) Caution: risk of restart!
The start command (e.g. via PLC) must be reset if a general fault occurs as an automatic restart is executed
when a start command is pending after the reset command is issued. This applies to motor protection
tripping in particular.
For safety reasons, we recommend integrating the general fault output (terminals 95 and 96) into the
control.

If the "DC braking" function is selected, a braking contactor must be additionally used.
For types, refer to the "Branch Component Circuitry (Standard Circuit)" table on Page 10-17.
The "DC braking" function is recommended for applications with larger centrifugal masses (JLoad > JMotor).
Output 2 must be set to "DC braking contactor".

2) Caution: risk of restart!
The start command (e.g. by the PLC) must be reset before a reset
command is issued, as an automatic restart is executed when a start
command is pending after the reset command is issued. This
particularly applies to motor protection tripping.
For safety reasons, we recommend integrating the general fault output
(terminals 95 and 96) into the control.

Note
With this circuit type, the motor start may be delayed by up to 5 s after the start command is issued due to
the internal run times of the soft starter. Coasting down is the only possible stopping mode.
Notice
After switching off the control supply voltage and before restarting, the device
must be allowed to cool down for at least 30 s, as this influences the
effectiveness of the inherent protection of the soft starter.
This type of circuit is not recommended for higher switching frequencies as the
integrated fan cannot idle after the soft starter has been switched off, thus
reducing the switching frequency specified in the technical data.

Note: parameterization
Set the control input functions to:
IN1: Motor right PS1
IN2: Motor left PS1
IN3: Slow speed mode
IN4: Trip/Reset (factory default)
The slow speed parameters in Parameter Set 1 must be set. Motor right means rotation in line phase direction, motor left means rotation against the line
phase direction.
Notice
The slow speed function is not suitable for continuous operation. The motor can overheat at slow speed during continuous operation.
Caution: risk of restart:
The start command must be reset before a reset command is issued, as an automatic restart is executed when a start command is pending after the reset
command is issued. This applies to motor protection tripping in particular.
K1, K2, K3 = relays for contact multiplication, e.g. for 230 V AC operation: 3RS 1800-1BP00

1) If the ramp-down function "Combined braking" is selected, no braking contactor is required.
If the ramp-down function "DC braking" is selected, a braking contactor must also be used (see table for type).
For applications with large centrifugal masses (JLoad > JMotor) we recommend the function "DC braking".
2) Additional auxiliary relay K4:
LZX:RT4A4T30 (soft starter with rated control supply voltage 230 V AC), LZX:RT4A4S15 (soft starter with rated control supply voltage 115 V AC).
3) The types of coordination are explained in more detail in the Technical information LV 1 T under – Fuseless Load Feeders.

1) If the ramp-down function "Combined braking" is selected, no braking contactor is required.
f the ramp-down function "DC braking" is selected, a braking contactor must also be used (see table for type).
For applications with large centrifugal masses (JLoad > JMotor) we recommend the function "DC braking.
2) Additional auxiliary relay K4:
LZX:RT4A4T30 (3RW44 soft starter with rated control supply voltage 230 V AC), LZX:RT4A4S15 (3RW44 soft starter with rated control supply voltage
115 V AC)).
3) The types of coordination are explained in more detail in the Technical information LV 1 T under – Fuseless Load Feeders.
