0.55 kW to 18.5 kW (0.75 hp to 25 hp)
SINAMICS G120C compact inverters
■
Overview
SINAMICS G120C frame sizes FSA, FSB and FSC with mounted
blanking cover
SINAMICS G120C compact inverters offer a well-balanced
combination 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 perfor-
mance.

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; the PROFINET version can be butt-
mounted up to 55 °C (131 °F).
SINAMICS G120C, frame size FSB, with BOP-2
SINAMICS G120C can be integrated into the widest range of ap-
plications, either using the integrated digital and analog inputs
or via the integrated fieldbus interface (available in the USS,
Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP, CANopen
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 seamless TIA product family to be fully utilized.
SINAMICS G120C drives are preset in the factory so that they
can be immediately connected to PROFIBUS, PROFINET or
CANopen fieldbus systems and used 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.
Line-side components
Line reactors
Line reactors smooth the current drawn by the inverter and thus
reduce harmonic components in the line current. Through the re-
duction of the current harmonics, the thermal load on the power
components in the rectifier and in the DC-link capacitors is re-
duced as well as the harmonic effects on the supply. The use of
a line reactor increases the service life of the inverter.
Recommended line-side power components
Standard fuses can be used for the SINAMICS G120C. These
must be dimensioned to comply with local regulations. In this
chapter, you will find recommended components such as fuses
and circuit breakers in compliance with IEC and UL regulations.
