Benefits
7
The converters are exceptionally quiet and compact thanks to
state-of-the-art IGBT power semiconductors and an innova-
tive cooling concept.
7
The clock frequency is optimized to reduce system losses to
a minimum.
7
The "random pattern" function significantly reduces motor
noise.
7
Plant and system availability are increased by being able to
quickly and simply replace power components.
7
Essential spare parts can be requested at any time for any
individual converter by means of the "SparesOnWeb" Internet
tool.
7
Optimized use of components reduces cabinet dimensions to
a minimum.
7
Easy integration into automation solutions via analog and
digital interfaces. Number of interfaces can also be expanded
through installation of an optional peripheral board.
7
Data are transmitted over popular bus systems
(PROFIBUS DP, CANopen, Modbus RTU or Modbus TCP)
7
Fast, easy commissioning and parameterization using inter-
active menus on an operator panel with illuminated graphic
LCD and plain-text display, or PC-supported using the
IMS commissioning tool (Inverter Management Software).
7
The entire production process is required to meet stringent
quality standards and subject to extensive controls, thereby
ensuring a high degree of functional reliability during
installation, commissioning and operation.
■
Application
The SINAMICS G180 is especially suited to applications in
industries such as the
•
chemical industry
•
oil and gas industry
•
power plant and utilities industries
•
plastics industry
•
process industry
•
primary industry
•
test bench systems
•
conveyor systems
and for general mechanical engineering applications.
■
Design
Platform concept
All of the SINAMICS G180 versions are consistently based on an
integrated, standardized, common, modular platform concept.
Shared hardware and software components, as well as stan-
dardized tools for dimensioning, configuring and commissioning
tasks ensure a high level of integration between all components.
All devices – from the lowest rating class in compact unit form to
the largest version in the form of an air-cooled or liquid-cooled
cabinet unit – have the same features with a virtually identical
scope of functions.
All frequency converters in the SINAMICS G180 range operate
with the Control Board. All Control Boards utilize the same firm-
ware and all are operated via the Inverter Management Software
IMS. Both the IMS and the firmware can be upgraded and down-
graded as required to facilitate communication.

Function
Power unit
•
Complies with EMC guidelines defined in EN 61800-3 thanks
to line filter which is integrated as standard (with grounded
supply system)
- Category C2 for compact units in TN/TT system of the first
environment (residential area), category C1 available as an
option
- Category C3 for cabinet units (TN/TT system) of the second
environment (industrial area)
- Category C4 for compact and cabinet units in IT system of
the second environment (industrial area)
•
SINAMICS G180 converters cause minor line harmonics:
Thanks to line reactors integrated in cabinet units and DC
reactors integrated in compact units
•
Output filter to permit the use of long motor cables for motors
with standard insulation
•
Insulation monitoring for IT systems integrated in 500/690 V
units and ground fault monitoring for TN and TT systems
integrated in 400 V units
•
Wide range of input voltages
•
Lower additional motor noise emissions of typically 3 dB(A)
as well as minor losses in converter and motor thanks to
optimized pulse pattern and converter clock frequency
•
Units can be protected by standard fuses (gL characteristic)
•
Standardized user interface on units rated from 2.2 to
6600 kW
Control section
•
High level of protection for personnel and plant is provided by
protective separation of the safety extra-low voltage in accor-
dance with IEC/EN 61800-5-1 at the analog and digital control
inputs and outputs of the power unit.
Operation and settings
•
Straightforward to operate and set by means of a menu-
assisted, 4-line plaintext display with membrane keyboard
on the converter unit or remotely from the control room via
an RS485 link at a distance of up to 1000 m
•
Extensive range of functions using a Windows-based PC
operating program
Explosion protection
•
ATEX-certified tripping concept in accordance with Directive
94/9 EC for the safe operation of motors in hazardous zones 1
and 2, which means that no main contactor is required
Safe Torque Off
Available with options
G04
,
G05
,
G08
•
Shutdown mechanism to prevent unexpected starting.
Category 0 stop function in accordance with EN 60204-1
(stop by disconnection of power supply to the machine).
•
Functional safety in accordance with:
- SIL 2 as per EN 61508
- Category 3 to EN ISO 13849-1
- Performance Level (PL) d to EN ISO 13849-1
•
Functional safety in accordance with IEC 61508: SIL 3 is
possible in conjunction with options
