SIMATIC ET 200pro 39
Compact, intelligent motor starters
The intelligent ET 200pro motor starters are used for start-
ing and protecting motors and loads up to 5.5 kW. They are
available in the versions electromechanical Standard and
High Feature motor starters, and electronic High Feature
motor starter.
The electromechanical mo-
tor starter switches with
conventional contactors
and is available as direct or
reversing starter with optio-
nal 400 V brake control.
The electronic motor starter
is equipped with semicon-
ductor switching elements
and therefore it is especially
suitable for applications with high switching frequencies. This
High-Feature device not only switches motors with a swit-
ching frequency on and off directly, it also implements the
function of a full-fledged soft starter for soft starting and stop-
ping. Conversion from motor starter to soft starter is imple-
mented by simple reparameterization in the SIMATIC Manager.
The High Feature motor starter differs from the Standard mo-
tor starter in that it has more parameters and four paramete-
rizable 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 in-
stallation – and they increase the availability of production
plants.
Easy installation
The compact ET 200pro motor starters 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 station in
the field.
Electronic current measurement
The actual current flow with the ET 200pro motor starter is
measured electronically. The evaluation of defined current
limits for the parameterizable electronic 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 availability. The motor starter
recognizes unbalanced load currents, and switches these off
directly. All motor protection functions can be defined by sim-
ple parameterization. The local control station which is some-
times required for a drive is provided via the integral digital in-
puts (High Feature motor starter) and can therefore be easily
incorporated into the control system.
Special modules for further functions
If required, an optional repair
switch module can be used.
For example, it isolates
series-connected starters
from the supply voltage or
serves as short-circuit protec-
tion for series-connected
loads with 25 A circuit-brea-
kers (group fusing).
Safety modules
The Safety Motorstarter Solu-
tion local or Solution PROFI-
safe is used for safety-orien-
ted 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 shutdown of the 400 V supply of the series-con-
nected motor starters.
PROFIsafe solutions are implemented quickly and easily by
using an F switch module in combination with a 400 V discon-
necting module.
