SIMATIC ET 200pro48
Compact, intelligent motor starters
The intelligent ET 200pro motor starters are used for start-
ing and protecting motors and loads of up to 5.5 kW. They
are available as Standard and High Feature electrome-
chanical motor starter and High Feature electronic motor
starter versions.
The electromechanical mo-
tor starter is switched with
conventional contactors
and is offered as direct or
reversing starter with op-
tional 400 V brake control.
The electronic motor start-
er is equipped with semi-
conductor switching ele-
ments and is therefore es-
pecially suited for applica-
tions with high switching
frequencies. This high fea-
ture device not only handles the direct on/off switching of
motors with high switching frequency, but also fulfills the ad-
ditional function of a full-fledged soft starter for a soft start-
up and stoppage. The conversion from motor starter to soft
starter is achieved using simple re-parameterization in
SIMATIC Manager.
The High Feature motor starters differ from the Standard mo-
tor starters in that they have more parameters and feature
four parameterizable digital inputs. Parameterization is easy
and convenient to carry out using the SIMATIC Manager.
The motor starters ET 200pro feature high functionality with a
small footprint, as well as simple and fast configuration and
installation – and they increase the availability of production
plants.
Easy installation
The compact ET 200pro motor starter can be installed in the
ET 200pro station with just a few actions. The integral connec-
tor technology results in significant reduction of the wiring
overhead. The motor cables can be plugged directly onto the
motor starter module. The compact design enables up to
eight motor starters to be integrated in a one meter wide sta-
tion in the field.
Electronic current measurement
The actual current flow with the ET 200pro motor starter is
measured electronically. In addition, the motor starter is now
available with PROFIenergy functionality. This makes it possi-
ble to selectively shut down motors via PROFINET during
breaks. Energy-related data such as the motor current can also
be integrated into higher-level control systems. Faceplates are
offered for PCS7 for visualizing diagnostics data. The evalua-
tion of defined current limits for the parameterizable electron-
ic overload protection increases the availability of the drive
system. An upward or downward violation is signaled by the
ET 200pro to the host controller, resulting in high plant avail-
ability.
The motor starter recognizes unbalanced load currents, and
switches these off directly. All motor protection functions can
be defined by simple parameterization. The local control sta-
tion which is sometimes required for a drive is provided via the
integral digital inputs (High Feature motor starter) and can
therefore be easily incorporated into the control system.
Special modules for further functions
If required, a maintenance
switch module can be used
that isolates series-connected
starters from the supply volt-
age, for example.
Safety modules
The Safety Motorstarter
Solution local or Solution
PROFIsafe is used for safety-
oriented applications.
For local safety applications,
the safety local repair switch
module with safe input and
the 400 V disconnecting
module are used. These two components permit a safe shut-
down of the 400 V supply of the series-connected motor start-
ers.
PROFIsafe solutions are implemented quickly and easily by us-
ing an F switch module in combination with a 400 V discon-
necting module.
