SINAMICS G120D distributed inverters
■
Design
The SINAMICS G120D distributed inverters are modular invert-
ers for standard drives. Each SINAMICS G120D comprises two
operative units – a Power Module and a Control Unit.
PM250D Power Module with line supply and motor connections and
CU240D-2 Control Unit
Power Modules
The following Power Modules are available for the
SINAMICS G120D distributed inverters:
PM250D Power Modules
PM250D Power Modules (0.75 kW to 7.5 kW/1 hp to 10 hp)
have an innovative circuit design which allows line-commutated
energy recovery back into the line supply. This innovative circuit
permits generated energy to be fed back into the supply system
and therefore saves energy.
Control Units
A Control Unit performs closed-loop control functions for the
inverter. In addition to the closed-loop control, it has additional
functions that can be adapted to the particular application
through parameterization.
The following Control Units are available for SINAMICS G120D
distributed inverters:
CU240D-2 Control Units
Several Control Units are available in different versions:
• CU240D-2 DP
→
PROFIBUS
• CU240D-2 DP-F
→
PROFIBUS fail-safe
• CU240D-2 PN
→
PROFINET
• CU240D-2 PN-F
→

CU250D-2 Control Units
CU250D-2 Control Units can be used to implement applications
with positioning requirements in the drive. Several Control Units
are available in different versions:
• CU250D-2 DP-F
→
PROFIBUS fail-safe
• CU250D-2 PN-F
→
PROFINET fail-safe
• CU250D-2 PN-F PP
→
PROFINET fail-safe Push Pull
• CU250D-2 PN-F FO
→

Supplementary system components
Intelligent Operator Panel IOP Handheld
The IOP supports both entry-level personnel and 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.
Memory card
The parameter settings for an inverter can be stored on the
SINAMICS SD card. When service is required, e.g. after the in-
verter has been replaced and the data have been downloaded
from the memory card the drive system is immediately ready for
use again. The associated slot is located on the rear of the
Control Unit.
Mini USB interface cable for communication with a PC
For controlling and commissioning an inverter directly from a PC
if the appropriate software (STARTER commissioning tool V4.3
and higher or SINAMICS Startdrive) has been installed.
Connecting cable for the Control Units
Flexible plug-in cables to transfer data between the Industrial
Ethernet stations or PROFIBUS stations, as well as to supply
power to the Control Unit.
Connecting cable for the Power Modules
Connector sets to connect to the line supply and the outgoing
motor feeder are available as accessories as well as pre-
assembled motor cables for connection to the motor.
Spare Parts Kit
A Spare Parts Kit is available which comprises small parts such
as seals, caps, PROFIBUS address windows and screws.
Replacement fan
A replacement fan is available, which comprises a pre-mounted
unit with cover, fan and screws.
