SINAMICS G120D distributed inverters
0.75 kW to 7.5 kW (1 hp to 10 hp)
SINAMICS G120D distributed inverters
■
Overview
The SINAMICS G120D distributed inverters are the solution
for demanding drive tasks especially in the field of conveyor
systems. SINAMICS G120D inverters continuously control the
speed of three-phase asynchronous (induction) motors and fulfill
all the requirements of conveyor system applications from
simple frequency control through to demanding vector control
and positioning requirements. With its intelligent modular design
with IP65 degree of protection, it can be seamlessly integrated
into the plant or system and supports a high plant availability
and low stocks of spare parts. The innovative power unit con-
cept capable of energy recovery helps to save energy. The
patented implementation concept of the integrated safety func-
tions is unique worldwide and has been extended further, with-
out the use of external components. This drive can be optimally
integrated into the Siemens TIA world of automation via
PROFIBUS or PROFINET / EtherNet/IP.
With different device versions (frame sizes FSA to FSC) in a
power range from 0.75 kW to 7.5 kW, it is suitable for a wide
variety of drive solutions.
Example: SINAMICS G120D, frame size FSA, comprising
PM250D Power Module and fail-safe CU250D-2 PN-F Control Unit
Reasons for using distributed drive systems
•
Modular drive solutions – therefore standardized mechatronic
elements that can be individually tested
•
A control cabinet is not required, resulting in a smaller space
requirement and lower cooling requirements
•
Long cables between the inverter and motor can be avoided
(which means lower power losses, reduced noise emission
and lower costs for shielded cables and additional filters)
•
Distributed configurations offer considerable benefits for
conveyor systems with their extensive coverage (e.g. in the
automotive and logistics sectors)
Siemens family of distributed drives
Siemens offers an innovative portfolio of frequency inverters to
optimally implement distributed drive solutions. The strengths of
the individual members of the drive family permit simple
adaptation to the widest range of application demands:
•
Identical connection systems
•
Identical mounting dimensions for SINAMICS G110D and
SINAMICS G120D
•
Standard commissioning and configuration tool
Products from the family of distributed drives:

Modularity
SINAMICS
G120D is a modular inverter system with IP65 degree
of protection comprising various function units. The main units
are
•
Control Unit (CU)
•
Power Module (PM)
The Control Unit controls and monitors the Power Module and
the connected motor using several different closed-loop control
types that can be selected. The digital inputs, analog inputs and
digital outputs on the device support the simple wiring of sen-
sors and actuators directly at the drive. The input signals can
either be directly linked within the Control Unit and initiate local
responses independently or they can be transferred to the cen-
tral control via PROFIBUS or PROFINET / EtherNet/IP for further
processing within the context of the overall plant.
The Power Module supplies the motor in a power range from
0.75 kW to 7.5 kW (1 hp to 10 hp). The Power Module is con-
trolled by a microprocessor in the Control Unit. State-of-the-art
IGBT technology with pulse-width-modulation is used for highly
reliable and flexible motor operation. Comprehensive protection
functions provide a high degree of protection for the Power
Module and the motor. The unusually low profile mechanical
design is optimized so that the device can be directly used in the
plant or system. The Power Module also has the same drilling
dimensions for all power ratings (standard footprint). Further, the
dimensions are identical to those of SINAMICS G110D. This
significantly simplifies the mechanical design, installation and
retrofit of a system.
