1.3 Operating principle
SIRIUS 3RW50 soft starter
Manual, 09/2019, A5E35628455002A/RS-AA/001 11
1.3 Operating principle
Soft starters are used to start three-phase induction motors with reduced torque and reduced
starting current.
The 3RW50 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
(switching elements) which start the motor up smoothly.
The 3RW50 soft starter features internal run-up recognition. If a successful motor run-up is
detected before the ramp up time elapses, the motor voltage is immediately increased to
100 % of the line voltage (t2). The internal bypass contacts close and the power
semiconductors are bypassed. The 3RW50 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. As long as the stopping time is active (t4to t5), energy is still supplied to
the motor. It may take longer for the motor to actually coast down to a standstill (t6).

Control source and master control function
The operating modes assign access rights to the various control sources (access sources).
The control source that possesses the rights for controlling and writing access has master
control function. As only one control source can ever possess the master control function at
one time, different priorities are assigned to the modes. Read access is also possible without
master control function.

independently of the mode in accordance with the parameter "Control via digital input"
(Page 139).
If other connections between the control source and 3RW50 soft starter are aborted, the
master control function automatically switches back to the lowest priority of the current
mode.
●"Automatic" mode: The 3RW50 soft starter behaves in accordance with the parameter
"Control via digital input" (Page 139).
●Operating mode "manual - bus": The master control function switches to
"Manual - bus - Connection abort".

3RW5 communication module in question.
1.5.2 Sets the operating mode
Fundamental response when changing the mode
A higher-priority mode can 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.
Requirements
●A mode with lower priority can only take the master control function back while the motor
is switched off.
●For the "Automatic" mode and "Manual - bus" mode you require a
3RW5 communication module.

1.5 Operating modes and master control function
SIRIUS 3RW50 soft starter
18 Manual, 09/2019, A5E35628455002A/RS-AA/001
"Automatic" mode
Receive master control function
The "Automatic" mode receives the master control function from the "Manual - bus" or
"Manual - local" mode as follows:
●Command in SIRIUS Soft Starter ES (TIA Portal) Premium (fieldbus)
●Action "LOCAL / REMOTE" on the 3RW5 HMI
●Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
Assume master control
By disabling 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), the "Automatic" mode receives the master control function
from the Input IN.
Relinquish master control
By enabling 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) the "Automatic" mode gives up the master control function to
the Input IN.
Revocation of the master control by other control sources
In the "Automatic" mode, the master control function can be withdrawn from any control
source.
Operating mode "manual - bus"
Assume master control
SIRIUS Soft Starter ES (TIA Portal) Premium actively assumes the master control function
from the "Automatic" mode in the event of a corresponding command.
Relinquish master control
SIRIUS Soft Starter ES (TIA Portal) Premium actively passes on the master control function
to the "Automatic" mode in the event of a corresponding command.
Revocation of the master control by other control sources
The master control function is withdrawn from the operating mode "manual - bus" by the
operating mode "manual - local" as follows:
●Activation of 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)
●Action "LOCAL / REMOTE" on the 3RW5 HMI
●Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)

Manual, 09/2019, A5E35628455002A/RS-AA/001 19
"Manual operation local - input controlled" mode
Assume master control
By enabling 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), the Input IN receives the master control function from the
"Automatic" mode or operating mode "manual - bus".
If the master control function is on the 3RW5 HMI or, in the case of the local interface, on the
3RW5 HMI High Feature (higher priority), you must actively give up the master control
function beforehand. Subsequently the Input IN can assume the master control function.
Relinquish master control
By disabling 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), the "Automatic" mode receives the master control function.
Revocation of the master control by other control sources
The master control function is withdrawn from the Input IN as follows:
●Action "LOCAL / REMOTE" on the 3RW5 HMI
●Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
"Manual operation local - HMI controlled" mode
Assume master control
The 3RW5 HMI actively assumes the master control function via the action "LOCAL /
REMOTE" from the lower priority control source.
If the master control function at the local interface on the 3RW5 HMI High Feature (higher
priority), you must actively give up the master control function beforehand in
SIRIUS Soft Starter ES (TIA Portal). You can then assume the master control function by
means of the action "LOCAL / REMOTE".
Relinquish master control
The 3RW5 HMI actively gives up the master control function via the action "LOCAL /
REMOTE" to the "Automatic" mode or alternatively to the Input IN. In the following cases the
master control function is given up to the Input IN.
●No 3RW5 communication module is connected to the 3RW50 soft starter.
●The parameter "Control via digital input" (Page 139) is set to "Permanent activation".
Revocation of the master control by other control sources
In the event of a corresponding command in SIRIUS Soft Starter ES (TIA Portal) at the local
interface on the 3RW5 HMI High Feature, the master control function is taken from the
3RW5 HMI.

Assume master control
If there is a corresponding command, SIRIUS Soft Starter ES (TIA Portal) actively assumes
the master control function from every control source.
Relinquish master control
If there is a corresponding command, SIRIUS Soft Starter ES (TIA Portal) actively gives up
the master control function to the "Automatic" mode or alternatively to the Input IN. In the
following cases the master control function is given up to the Input IN:
●No 3RW5 communication module is connected to the 3RW50 soft starter.
●The parameter "Control via digital input" (Page 139) is set to "Permanent activation".
Revocation of the master control by other control sources
The master control function cannot be withdrawn from SIRIUS Soft Starter ES (TIA Portal)
by any control source.
