SINAMICS G150
Engineering Information
Due to the design principle of using two separate, low-output converter cabinet units, the configuration includes two
each of the following components:
•
Mains supply connections
•
Main switch and main contactors
•
All power unit components
•
Motor connections
A parallel connection features only one of each of the following:
•
CU320 Control Unit, which controls and synchronizes both individual power units
•
AOP30 operator panel
•
TM31 customer interface (analog and digital inputs and outputs)
Note:
In contrast to the S120 Infeed Modules and the S120 Motor Modules of the SINAMICS S120 modular system
(Chassis and Cabinet Modules) in which up to four individual modules can be combined to a parallel connection, the
G150 parallel converter / G150 power extension is a ready-to-connect converter cabinet unit comprising two
converter cabinet units with lower outputs. It is ordered and supplied as a single unit with one order number. The
technical data provided in the catalogs and in the tables of this engineering manual always refer to the complete
G150 parallel converter and include already the current and power derating factors required for parallel connections.
The table below shows the power spectrum of the SINAMICS G150 parallel converters. For information purposes
only, the last column contains the rated output current of the relevant individual cabinet units on which the parallel
converter is based.

Power range of SINAMICS G150 parallel-connected converters
Since SINAMICS G150 parallel converters consist of two identical rectifiers on the line side, the rectifiers can operate
either in 6-pulse or in 12-pulse configuration. The harmonic effects on the supply system are significantly lower in the
12-pulse operation than in the 6-pulse operation (see section "Harmonic effects on supply system" of the chapter
"Fundamental Principles and System Description").
On the line side, certain conditions must be taken in account depending on whether the configuration is a 6-pulse or a
12-pulse configuration.
On the motor side, limitations exist related to the necessary minimum cable lengths for the motor and also to the
permissible pulse modulation systems of the inverter, depending on the winding system in the motor (electrically
isolated winding systems or one common winding system).
The following information describes the possible line-side and motor-side configurations of SINAMICS G150 parallel
converters and the associated supplementary conditions that have to be taken in account.
