For standard motors: Single- or three-phase asynchronous motors, single-
phase AC motors, single-phase asynchronous motors, at 400 V AC and
500 V AC; the actual startup characteristics of the motor as well as its rated
data are important factors here.
Note:
The Article No. scheme shows an overview of product versions
for better understanding of the logic behind the article numbers.
For your orders, please use the article numbers quoted in the
selection and ordering data.
BaseUnits for motor starters
BaseUnits are components for accommodating the ET 200SP
I/O modules. The self-assembling voltage buses integrated into
the terminal modules reduce wiring outlay to the single infeed
(both of auxiliary and load voltage).
All modules following on the right are automatically supplied
upon plugging the BaseUnits together, if BaseUnits are inserted
with routing. The rugged design and keyed connection
technology enables use in harsh industrial conditions.
The BaseUnits are available with various infeeds for the motor
starters.

3DI/LC control module
This is a digital input module with three inputs for local motor
starter functions such as "manual local control", implementation
of fast inputs or "end position disconnection".
For a list of all the functions permitted by the 3DI/LC module,
see
Manual "ET 200SP Motor Starters", "Function overview" section
The module is plugged into the front of the motor starter from
which it is supplied with a 24 V DC operating voltage.

Benefits
Product advantages
The ET 200SP motor starters offer a number of advantages:
•
Fully integrated into the ET 200SP I/O system
(including TIA Selection Tool and TIA Portal)
•
Simple, integrated current value transmission
•
Extensive parameterization by means of TIA Portal
•
Increase of plant availability through fast replacement of units
(easy mounting and plug-in technology)
•
Greater endurance and reduced heat losses thanks to hybrid
technology
•
Less space required in the control cabinet (20 to 80 %)
as a result of greater functional density (direct-on-line and
reversing starters in same width)
•
Extensive diagnostics and information for preventive
maintenance
•
Parameterizable inputs via 3DI/LC control module
•
Less wiring and testing required as a result of integrating
several functions into a single device
•
Lower overheads for stock keeping and configuration as
a result of the wide setting range of the electronic overload
release (up to 1:3)
•
Technology-reduced inherent power loss as speed-controlled
drive systems, enabling also lower cooling effort required
(and enabling a more compact design)
The ET 200SP motor starters can be used with highly
energy-efficient IE3/IE4 motors.
For more information on IE3/IE4,
