SINAMICS
G120P is a modular converter system comprising the
following components.
•
CU230P-2 Control Unit
•
Power Module
•
Operator panel or blanking cover
CU230P-2 Control Unit
The converter communication interface is defined when
selecting the Control Unit (FW V4.5 and higher).
• CU230P-2 HVAC
→
USS, Modbus RTU, BACnet MS/TP, FLN P1
• CU230P-2 DP
→
PROFIBUS
• CU230P-2 PN
→
PROFINET, EtherNet/IP
The CU230P-2 Control Unit controls and monitors the Power
Module and the connected motor using several different closed-
loop control modes that can be selected. It supports communi-
cation to a local or central controller as well as to the monitoring
equipment, and allows all process-related auxiliary equipment
and external components to be connected (sensors, valves,
contactors, etc.).
Power Modules
The Power Module is selected depending on the power require-
ment and the application. State-of-the-art IGBT technology with
pulse-width modulation is used for reliable and flexible motor
operation. Comprehensive protection functions provide a high
degree of protection for the Power Module and the motor.
Power Modules for use in building technology for heating,
air conditioning and ventilation applications
The Power Modules in degree of protection IP20 are intended
for installation in a control cabinet:
•
PM230 with integrated filter class A, 0.37 kW to 75 kW
•
PM230 without integrated line filter, 0.37 kW to 75 kW
•
PM230 with integrated filter class A, Push Through variant,
3 kW to 18.5 kW
•
PM230 without integrated line filter, Push Through variant,
3 kW to 18.5 kW
The Power Modules in degree of protection IP55 can be erected
as distributed units outside a control cabinet.
•
PM230 with integrated filter class A, degree of protection IP55,
0.37 kW to 90 kW
•
PM230 with integrated filter class B, degree of protection IP55,
0.37 kW to 90 kW
Power Modules for use in the water/wastewater sector as well as
in industrial applications
The Power Modules in degree of protection IP20 are intended for
installation in a control cabinet:
Line voltage 380 V to 480 V 3 AC
•
PM240P-2 with integrated filter class A, 22 kW to 132 kW
•
PM240P-2 without integrated line filter, 22 kW and 132 kW
•
PM330 without integrated line filter, 160 kW to 560 kW
Line voltage 500 V to 690 V 3 AC
•
PM240P-2 with integrated filter class A, 11 kW to 132 kW
•
PM240P-2 without integrated line filter, 11 kW and 132 kW
•
PM330 without integrated line filter, 315 kW to 630 kW
SINAMICS G120P Cabinet
SINAMICS G120P units rated for outputs of 75 kW and
higher are also available in the control cabinet version
SINAMICS G120P Cabinet for line voltages of 380 V to
480 V 3 AC and 500 V to 690 V 3 AC.
•
SINAMICS G120P Cabinet, degrees of protection IP20/IP21/
IP23/IP43/IP54, 75 kW to 630 kW, with and without line filter
Operator panel or blanking cover
•
Intelligent Operator Panel IOP, degree of protection IP54
The IOP supports entry-level personnel as well as drive
experts. Thanks to the large plain text display, the menu-
based operation and the application wizards, it is easy to
commission, diagnose and locally control standard drives.
Optionally available wizards
1)
interactively guide users
through the commissioning process.
•
Basic Operator Panel BOP-2, degree of protection IP55
The menu prompting and the 2-line display allow for the fast
and user-friendly commissioning of the converter. Simulta-
neous display of the parameter and parameter value, as well
as parameter filtering, means that basic commissioning of a
drive can also be performed without a printed parameter list.
•
Blanking cover, degree of protection IP55
The blanking cover is mounted on the Power Module in place
of an operator panel, provided that an operator panel is not
required.
The operator panel supports user-friendly local commissioning,
control and diagnostics and enables complete converter data
sets to be pre-parameterized and cloned.
Note for PM230 Power Modules, degree of protection IP55
It is essential to plug on an operator panel or the blanking cover
in order to achieve degree of protection IP54/IP55.
Line-side power components
The following line-side power components are available for the
SINAMICS G120P converters:
•
Line filters for PM230 and PM330 Power Modules and
SINAMICS G120P Cabinet
With an additional line filter, the Power Module complies with a
higher radio interference class.
•
Line reactors for PM330 Power Modules and
SINAMICS G120P Cabinet
Line reactors smooth the current drawn by the converter and
thus reduce harmonic components in the line current. Through
the reduction of the current harmonics, the thermal load on the
power components in the rectifier and in the DC link capaci-
tors is reduced as well as the harmonic effects on the supply.
The use of a line reactor increases the service life of the
converter.
SINAMICS G120P Cabinet units feature a cabinet-integrated
line-side reactor as standard.
Note:
A line reactor must not be used in combination with a PM230
Power Module.
Recommended line-side power components
This section contains recommendations for additional line-side
components, such as fuses and circuit breakers (line-side com-
ponents must be dimensioned in accordance with IEC stan-
dards).
Additional information about the listed fuses and circuit breakers
is available in Catalogs LV 10, IC 10 and IC 10 AO.
