SIMATIC ET 200pro 49
Two types of frequency converters
With the structure of a SIMATIC module, the frequency
converter SIMATIC ET200pro FC can be smoothly inserted
into the ET200pro system. Two device variants (with and
without safety functions) are available for output up to
1.1 kW (1.5 kW with reduced ambient temperature).
The communication can be achieved via PROFINET or
PROFIBUS.
Flexible and fast
The integration of the frequency converter in the distributed
I/O system SIMATIC ET 200pro offers the following benefits:
• Flexibility due to open combination of ET 200pro modules
with the frequency converter
• 400 V power transmission to downstream converters via
jumper plugs up to 25 A
In addition, the ET 200pro FC features a multitude of high-
lights of the SINAMICS drive family:
• V/f control and sensor-free frequency adjustment
• Energy efficiency through power recovery and reactive
power compensation
• Feedback of braking energy in the network (the same tech-
nology as the SINAMICS-G120 power module PM250) so
that braking resistor and braking chopper are eliminated.
• Integrated safety functions: functional safety without a
costly external protective circuit
• Optional Micro Memory Card for automatic download of
parameters
• Design of the system motor frequency converter with the
SIZER (as of Version 2.8)
• Parameterization via STARTER (as of Version 4.1, SP1)
Integrated safety functions
The fail-safe design of SIMATIC ET 200pro FC offers compre-
hensive safety functions, certified in accordance with Catego-
ry 3 of EN954-1 and SIL 2 of IEC61508.
• Safe Torque Off (STO, previously "Safe Standstill") – for pro-
tection against an active movement of the drive.
• Safe Stop 1 (SS1, previously "Safe Braking Ramp") – for con-
tinuous monitoring of a safe braking ramp.
• Safely Limited Speed (SLS, previously "Safely Reduced
Speed) – for protection against hazardous movements
caused by exceeding a speed limit.
Neither of the functions "Safe Stop 1" or "Safely Limited Speed"
requires a motor encoder or other encoder. The safety func-
tions can be controlled using inputs of the Safety Local main-
tenance switch module (F-RSM) or the module F Switch
PROFIsafe.
