Drive Control Chart (DCC)
The "Drive Control Chart" function (DCC) is available for more
complex applications.
DCC allows you to graphically configure the required functional-
ity and then download it to the drive. It provides a significantly
extended range of block types available.
In online operation, the signal values can be monitored in
STARTER/SCOUT in the DCC chart.
Power section and cooling
SINAMICS DC MASTER converters distinguish themselves as a
result of the compact, space-saving design. The electronics
module (available in various customer-specific combinations
with options) is installed in a cradle that can be swiveled out. The
easy access to individual components makes this technology
very service-friendly.
Plug-in terminals are used to connect external signals (binary
inputs/outputs, analog inputs/outputs, pulse generators etc.).
The firmware is saved in a flash EPROM and can be easily
exchanged by loading via the serial interface of the
SINAMICS DC MASTER.
Power section: Armature and field circuit
The armature circuit is implemented as a three-phase bridge
circuit:
•
For units for two-quadrant operation, in a fully-controlled three-
phase bridge circuit B6C
•
For units for four-quadrant operation in two fully-controlled
three-phase bridge circuits (B6) A (B6) C.
The field circuit is implemented in a half-controlled single-phase
bridge circuit B2HZ.
In the case of units with a 15 A to 1200 A rated DC current, the
power sections for the armature and field include electrically
isolated thyristor modules, which means that the heat sink is
floating. For units up to 30 A, the armature and field power
sections are implemented in the form of a printed circuit board
with compact modules that are soldered on.
For units with rated currents
≥
1500 A, the power section for the
armature circuit uses disc-type thyristors and heat sinks at volt-
age potential. For units from 1500 to 3000 A, the thyristor phases
are implemented as plug-in modules and can therefore be
quickly replaced.
Checking the motor insulation has been significantly simplified
due to the fact that the line supply voltage sensing for the
armature and the field sections is electrically isolated.
Cooling
Units with a rated DC current up to 125 A are designed for
natural air cooling, units with a rated current above 210 A are
designed for forced air cooling (fan). The fans are always
horizontally mounted at the top so that they can be quickly
replaced without having to disconnect the power connections.
Parameterizing devices
BOP20 Basic Operator Panel
BOP20 Basic Operator Panel
As standard, all of the units are equipped with a BOP20 Basic
Operator Panel from the SINAMICS family.
The basic operator panel offers customers a basic functionality
for commissioning as well as operator control and monitoring.
Faults can be acknowledged, parameters set and diagnostics
information read-out (e.g. alarm and fault messages) using the
BOP20.
The BOP20 has a backlit two-line display area and 6 keys.
The BOP20 power supply and communication with the CUD
Control Unit are established via the connector integrated at the
rear of the BOP20.
AOP30 Advanced Operator Panel
The AOP30 Advanced Operator Panel is an optional input/output
device for SINAMICS DC MASTER converters. It can be sepa-
rately ordered. You will find additional information about the
AOP30 in catalog section "Accessories and supplementary
components".
PC based parameterization
The STARTER tool is available for PC-based commissioning and
diagnostics. More detailed information is provided in catalog
section 5 "Tools and engineering".
