4 Converter Chassis Units SINAMICS G130

4.1 General information

The SINAMICS G130 Chassis are AC/AC converters for medium to high-output single drives that can be combined
very flexibly with the associated system components and integrated into customer-specific cabinets or directly into
machines.
They are designed for applications with low to medium requirements in terms of control quality and feature a simple
6-pulse rectifier without regenerative feedback capability.
The motor-side inverter is designed primarily to operate asynchronous motors in sensorless vector control mode.
Optionally it is also possible to operate asynchronous motors with incremental encoders.
SINAMICS G130 converters are available for the line supply voltages and output power ranges listed below:
Line supply voltage
380 V – 480 V 3AC
500 V – 600 V 3AC
660 V – 690 V 3AC
Line supply voltages and output power ranges of SINAMICS G130 Chassis units
SINAMICS G130 Chassis comprise two independent components:
·
Power Module
·
CU320-2 Control Unit
The Power Module includes the following components:
·
6-pulse rectifier for 1Q operation,
·
capacitors of the voltage-source DC link,
·
motor-side IGBT inverter,
·
gating and monitoring electronics (Control Interface Module CIM),
·
DC link precharging circuit,
·
fan(s) with appropriate voltage supply.
Power Module and Control Unit can be assembled close together or installed at separate locations. The Control Unit
can be mounted externally on the left-hand side panel of the Power Modules in the lower output power range (frame
sizes FX and GX). In the higher output power range (frame sizes HX and JX), the Control Unit can be installed in the
Power Module itself.
The Power Modules are supplied with a DRIVE-CLiQ cable for communication with the Control Unit and a cable for
the 24 V supply to the Control Unit. With these, the installation of the Control Unit on either the side of the Power
Module or within it is possible. If Power Module and Control Unit are placed at separate locations, the cables must be
ordered in the appropriate lengths.
The Control Unit is available in kit form which is a simpler ordering option. This kit comprises the CU320-2 Control
Unit, the CompactFlash card with the firmware for SINAMICS G130 and a product documentation CD. Two variants
of the kit are available:
·
Control Unit kit with CU320-2 DP (PROFIBUS)
·
Control Unit kit with CU320-2 PN (PROFINET)
Predefined interfaces via PROFIBUS (CU320-2 DP Control Unit), PROFINET (CU320-2 PN Control Unit) or terminal
blocks make it easier to commission and control the drive. The interfaces of the CU320-2 Control Unit can be
supplemented by additional modules, such as the TB30 Terminal Board which can be plugged into the option slot, or
the TM31 Terminal Module which can be mounted on standard DIN rails.
It is advisable to use the internal auxiliary power supply of the Power Module as the 24 V source for the Control Unit,
see section "Incorporating different loads into the 24 V supply".
If further customer interfaces are needed to communicate with the drive, it might be necessary to provide an external
24 V supply.
The drive system can be tailored optimally to meet the relevant requirements with numerous additional components
such as line fuses, line reactors, braking units, motor reactors and motor filters.
