5 Converter Cabinet Units SINAMICS G150

5.1 General information

SINAMICS G150 converter cabinets are ready-to-connect, high power output AC/AC converters in a standard
cabinet. An extensive range of electrical and mechanical options means that they can be configured easily to meet
individual requirements.
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 G150 converter cabinets 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 G150 converter cabinets
There are two versions of the SINAMICS G150 cabinets:
·
Version A
is designed to allow installation of all the available line connection components, such as line fuses,
main circuit breaker, main contactor, circuit breakers, line filter or motor-side components and
additional monitoring equipment. This version is also available in the higher power range with two
Power Units connected in parallel.
·
Version C
with specially space-optimized design without line-side components. This version can be used, for
example, when line connection components are accommodated in a central low-voltage distribution
panel (MCC) in the plant.
SINAMICS G150 cabinets are available in a range of cabinet widths, starting at 400 mm and increasing in increments
of 200 mm.
The standard model has a degree of protection IP20, but further models with degrees of protection IP21, IP23, IP43
and IP54 are available as options.
SINAMICS G150 cabinets feature as standard the AOP30 Advanced Operator Panel for control, monitoring and
commissioning tasks. It is mounted in the cabinet door.
A PROFIBUS interface is provided as standard on the CU320-2 DP Control Unit as a customer interface. If the
CU320-2 PN Control Unit (option K95) is used instead of the standard CU320-2 DP Control Unit, a PROFINET
interface is provided instead of the PROFIBUS interface.
The CU320-2 features digital inputs and outputs as standard. The TB30 Terminal Board (option G62) can be
optionally inserted in the CU320-2 option slot and / or the TM31 Terminal Module can be used (option G60 or G61).
These options provide additional digital and analog inputs and outputs.

5.2 Rated data of converters for drives with low demands on control performance

Main applications
SINAMICS G150 converter cabinet units are designed primarily for applications with low to medium requirements of
dynamic response and control accuracy and are usually operated in sensorless vector control mode. They can
operate asynchronous motors as well as permanent-magnet synchronous motors in sensorless vector control mode
without encoder.
For applications that require a higher standard of control performace, i.e. where the control accuracy is more
important than the dynamic response, SINAMICS G150 converter cabinet units can be equipped with an SMC30
speed encoder interface which enables them to operate asynchronous motors with TTL / HTL incremental encoders
(option K50).
SINAMICS G150 converter cabinet units are basically incapable of regenerative feedback. For applications where the
drive operates in regenerative mode for brief periods, it is possible either to activate the V
braking units (options L61 or L62).
