7.1

Overview of the functions

This chapter describes the functions that are not described in other parts of the supplied
documentation.
The functions of the SINAMICS DCM DC Converter converter unit are described in detail in
the relevant Operating Instructions, in the associated List Manual and in the Function Manual
"Free function blocks".
The functions of the SINAMICS DCM Cabinet provided by the options are described in the
document "SINAMICS DCM Cabinet, Description of options".
The underlying electrical circuit concept and the type-dependent variants of the electrical
versions of the converter cabinet standard types without options can be viewed in the single-
pole schematic circuit diagrams.

Scope of supply

Supply components
The basic version of SINAMICS DC MASTER Cabinet is a type-tested and ready-to-connect
system to operate a separately excited DC motor on a line-commutated converter. The basic
version is designed to operate on a TN-S or TN-C network. The following main components
are included in addition to the SINAMICS DC MASTER DC Converter:
● Line connection
● Main switch
● Line reactors
● Semiconductor fuses
● Main contactor or circuit breaker (power-dependent)
● Control voltage transformers
● Circuit breakers and motor circuit breakers for auxiliaries
● AOP30 advanced operator panel
● PROFIBUS port
● Interface to the higher-level analog and digital control and monitoring system of the plant
● Interface for detecting the actual motor values (speed, temperature)
● Cabinet fan (power-dependent)
In addition to the basic version, numerous options make it possible to adapt the converter
cabinet optimally to the plant requirements and to other line system configurations.
