Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

1.3 Operating principle
3RW51 Soft Starter
Manual, 06/2019, A5E37108631002A/RS-AB/002 9
1.3 Operating principle
Soft starters are used to start three-phase induction motors with reduced torque and reduced
starting current.
The 3RW51 soft starter starts the motor as soon as the switch-on command is issued (t1).
During the ramp-up time (t1to t3), the current is conducted via power semiconductors which
starts up the motor smoothly.
The 3RW51 soft starter features internal run-up recognition. The following operation occurs
when the motor reaches its rated operating speed before the ramp-up time expires:
●The motor voltage is immediately increased to 100 % of the line voltage (t2)
●The external bypass contactor close
●The power semiconductors are bypassed and the soft starter is in bypass operation.
Coast-down to zero speed is activated when the switch-on command is cancelled (t4) and
the motor is shut down. The power semiconductors also ensure that the motor coasts down
smoothly to a stop. The power supply to the motor is maintained (t5) until the end of the
ramp-down time is reached (t4to t5). It may take longer for the motor to actually coast down
to a standstill (t6).

controls
3RW5 HMI 3RW5 HMI controls Highest
If the connection to the control source is aborted, the control priority automatically switches
back to the lowest priority of the current mode.
Sets the operating mode
A higher-priority mode can actively take over as master control from a lower-priority mode at
any time; the reverse is not possible.
The master control function can only be returned to the mode with the lowest priority. Control
sources with higher priority must take the master control function from the mode with the
lowest priority.
A mode with lower priority can only take the master control function back while the motor is
switched off.
The mode with higher priority takes over or receives the master control function from the
current mode in the following ways:
●The mode with higher priority actively takes over the master control function:
–3RW5 HMI: With the action "LOCAL / REMOTE"
●The digital inputs receive the control priority from an operating mode with lower priority
via the following options:
–Via the "Manual operation local - input controlled" bit in the process image output
(PIQ) or in the data table "process image output (PIQ)" (depending on the 3RW5
communication module). You will find more information on the process images and
data tables in the manual for the 3RW5 communication module in question.
The mode with the lowest priority receives or takes over the master control function from the
current mode in the following ways:
●The mode with higher priority actively returns the master control function:
–3RW5 HMI: With the action "LOCAL / REMOTE"
●With control priority of the digital inputs or in the event of a connection abort, the
operating mode with the lower priority can actively retrieve the control priority:
–Via the "Manual operation local - input controlled" bit in the process image output
(PIQ) or in the data table "process image output (PIQ)" (depending on the 3RW5
communication module). You will find more information on the process images and
data tables in the manual for the 3RW5 communication module in question.

1.7 Areas of application / load types
Conveyor belts Pumps Compressors
Agitators
Fans
Saws
Starting of a motor causes a rapid change in the load current. The resulting torque impulses
place severe stresses on the mechanical parts of a machine or plant. Moreover, voltage dips
can occur in the power supply system which can have a negative influence on other devices:
●Flicker in lights
●Influence on computer systems
●Contactors and relays dropping out
The 3RW51 soft starter controls the voltage continuously. The torque and the current are
thus also increased continuously. The power supply system is safeguarded against peak
loads and the drive train is protected against damage:
●Smooth starting / stopping, e.g. for conveyor belts
●No pressure surges, e.g. for pumps
●Increased service life of the pipe system, e.g. for compressors
●Reduced starting current, e.g. for agitators
●Reduced stress on gearbox and V belt, e.g. for saws

1.8 Selection of the soft starter using the Simulation Tool for Soft
Starters
The soft starter can be configured with the STS (Simulation Tool for Soft Starters) software.
The STS suggests suitable soft starters for the respective application based on the entered
motor and load data and application requirements as well as providing information on the
parameterization.
The Simulation Tool for Soft Starters (STS) can be downloaded from the Internet
(https://support.industry.siemens.com/cs/ww/en/view/101494917).

1.10.2 3RW5 HMI
3RW5 HMI Standard
The 3RW5 HMI Standard can be used to monitor and control (motor ON / OFF) the 3RW51
soft starter and acknowledge faults. The 3RW5 HMI Standard can either be installed in the
3RW51 soft starter or in the control cabinet door (using accessories) or mounted on a wall
(using accessories). It features an LCD with red display illumination and for status display, as
well as function and control keys.
Functions
●Any changes of setting elements will be indicated immediately in the display.
●Error diagnostics are output as error numbers (Faults and remedial actions of the 3RW51
soft starter) (Page 123)
●Acknowledgment of faults and execution of test functions via the RESET / TEST key
●Starting and stopping the motor via control keys
●Mode change with the LOCAL / REMOTE key
●Setting the PROFIBUS or MODBUS slave address
●Display of the device LEDs of the 3RW5 HMI Standard shows the messages of the
following devices:
–3RW51 soft starter
–3RW5 HMI Standard
–Communication module (if there is one)

3RW5 HMI High Feature (HF)
The 3RW5 HMI High Feature can be used to parameterize, monitor and control (ON / OFF)
the 3RW51 soft starter. The 3RW5 HMI High Feature can either be installed in the 3RW51
soft starter or in the control cabinet door (using accessories) or mounted on a wall (using
accessories). It has a TFT color display, LEDs for displaying the system status as well as
function and control keys..
Functions
●Editable favorites key F1 - F9
●Language selection
●Starting and stopping the motor via control keys
●Display of error diagnoses as plain-text messages
●Display of up to 5 measured values at the same time
●Analog output and ON / RUN relay output can be parameterized with the 3RW5 HMI High
Feature under small load test mode and without bypass mode
●Setting communication parameters of 3RW5 communication modules:
–PROFINET (device names and the IP parameters)
–PROFIBUS (station address)
–Modbus RTU (server address)
●Backup of parameterization data
●Display of the device LEDs of the 3RW5 HMI High Feature shows the messages of the
following devices:
–3RW51 soft starter
–3RW5 HMI Standard
●Firmware update can be performed using the 3RW5 HMI High Feature and a memory
card for the following devices (Perform the firmware update with SD memory card (3RW5
HMI High Feature)) (Page 138)
