Application
The SINAMICS DC MASTER Control Module is mainly used for
retrofitting and modernizing DC drives in existing plants and
systems. There are many older DC installations in existence
which cannot be linked to modern automation systems.
When such plants and systems are retrofitted or upgraded, the
motor, mechanical system and power section are retained and
only the closed-loop control section is replaced by a Control
Module. As a consequence, an extremely favorably-priced
modern DC drive is obtained with the full functional scope of the
well-proven, fully digital units from the SINAMICS DC MASTER
series.
The new system is adapted to the configuration of the existing
components using simple parameterization.
The SINAMICS DC MASTER Control Module contains a power
section for the field supply with a rated current of 40 A.
■
Design
The SINAMICS DC MASTER Control Module sets itself apart as
a result of its compact, space-saving design. The compact
design where all of the individual components are easily
accessible offers a high degree of service friendliness.
In order to be able to optimally use the mounting and installation
possibilities in the plant or system, the SINAMICS DC MASTER
Control Module can be split depthwise. In addition, the PC
boards for generating and distributing firing pulses, and for fuse
monitoring and voltage sensing are designed in such a way that
they can be installed outside the device in close proximity to the
power section.
Alternatively, when commissioning the drive system with
STARTER, the adaptations, settings and measured value dis-
plays required can be made using the BOP20 Basic Operator
Panel or the AOP30 Advanced Operator Panel.
The AOP30 offers a favorably-priced alternative to measuring
equipment installed in the electrical cabinet.
The field is supplied from a single-phase, semi-controlled bridge
circuit B2HZ. The field power section is implemented using
electrically insulated thyristor modules, which means that the
heat sink is floating.

The field supply voltage can lie below the rated field voltage (set using a
parameter, input voltages of up to 85 V are permissible). The output voltage
decreases accordingly. The specified DC output voltage can be reliably
provided up to a 5 % undervoltage of the line supply voltage (rated field
supply voltage).
