SINAMICS G120C compact inverters
■
Overview
SINAMICS G120C frame sizes FSAA, FSA, FSB and FSC with mounted
blanking cover
SINAMICS G120C compact inverters offer a well-balanced com-
bination of features to address a wide range of applications.
They are compact, rugged devices that are easy to operate and
can be optionally equipped with a basic or advanced operator
panel.
SINAMICS G120C inverters are especially suitable when it
comes to meeting the requirements of system integrators, OEMs
and distributors regarding high productivity and tailored
performance.

Design
SINAMICS G120C is a compact inverter for control cabinet
mounting in IP20 degree of protection where the Control Unit
(CU) and Power Module (PM) function units are combined in one
device.
The compact mechanical design and the high power density
allow these devices to be installed in machine control enclo-
sures and control cabinets for maximum space utilization. The
SINAMICS G120C compact inverter can be butt-mounted
directly, without derating at temperatures up to 40 °C.

SINAMICS G120C can be integrated into the widest range of
applications, either using the integrated digital and analog in-
puts or via the integrated fieldbus interface (available in USS,
Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP versions).
Especially the product versions with integrated PROFIBUS/
PROFINET interface make full integration into the Siemens TIA
family possible, therefore allowing the advantages of the seam-
less TIA product family to be fully utilized. SINAMICS G120C
devices are preset in the factory so that they can be immediately
connected to PROFIBUS and/or PROFINET fieldbus systems
without parameterization.
SINAMICS G120C is also equipped with the safety function STO
(Safe Torque Off) as standard, which is used to safely stop
drives. As a consequence, machine manufacturers can simply
comply with current machinery directives with minimum associ-
ated costs.
SINAMICS G120C can control asynchronous (induction) motors
in the power range from 0.37 kW up to 18.5 kW (0.5 hp up to
25 hp). Reliable and efficient motor operation is achieved by
using state-of-the-art IGBT technology combined with vector
control. The extensive range of functions integrated in the
SINAMICS G120C also offers a high degree of protection for the
inverter and motor.
