SINAMICS Drive Control Chart (SINAMICS DCC)
■
Overview
SINAMICS Drive Control Chart (SINAMICS DCC) expands the
scope of device functions by means of freely available closed-
loop control, arithmetic and logic blocks and offers a means by
which technological functions can be graphically configured in
the SINAMICS drive system. SINAMICS DCC is the first stage of
the Advanced Technology Function and is installed as an add-
on to the STARTER commissioning tool.
SINAMICS DCC provides users with greater scope to adapt
these systems to the specific functions of their machines.
SINAMICS DCC does not limit the number of functions that
can be used. The number of functions is limited only by the
performance capability of the Control Unit.
SINAMICS DCC is available for the following SINAMICS drive
systems:
•
SINAMICS G130
•
SINAMICS G150
•
SINAMICS S120
•
SINAMICS S150
•
SINAMICS DCM
•
SINAMICS GM150
•
SINAMICS SM150
•
SINAMICS GL150
•
SINAMICS SL150
The user-friendly DCC editor enables easy graphics-based con-
figuration, allows control loop structures to be clearly represen-
ted and provides a high degree of reusability of diagrams that
have already been created.
The open-loop and closed-loop control functions are defined by
using multi-instance-capable blocks (Drive Control Blocks
(DCBs)) from a library (DCB library) that are selected and gra-
phically linked with one another by dragging and dropping. Test
and diagnostic functions allow the program behavior to be veri-
fied and, in the case of a fault, the cause identified.
Two types of DCB library are available, i.e. DCB Standard
and DCB Extension. The DCB Standard library supplied with
SINAMICS DCC contains a large selection of closed-loop,
arithmetic and logic blocks, as well as comprehensive open-
loop and closed-loop control functions.
For logically combining, evaluating and acquiring binary sig-
nals, all commonly used logic functions are available for selec-
tion (AND, XOR, on/off delay, RS flipflop, counter, etc.). A wide
range of arithmetic functions, such as absolute value generation,
dividers and minimum/maximum evaluation are available to
monitor and evaluate numerical quantities. In addition to the
closed-loop drive control, axial winder functions, PI controllers,
ramp-function generators or wobble generators are simple to
configure.
In addition to the standard library, the DCB Extension library is
also available with SINAMICS DCC, firmware version V4.6 and
higher. This contains an extended range of blocks that can be
used as an additional, independent library in the DCC Editor.
DCB Extension provides new motion control blocks as a GMC
library.
Using these blocks, it is possible to implement the following
positioning and synchronous operation functions with
SINAMICS DCC:
• Positioning
•
1:1 synchronous operation
• Gearing
•
Gearing and positioning
• Camming
These applications are available for downloading from the
Internet on the Siemens Application Support pages at
With the blocks provided by DCB Extension, it is also possible to
commission the programming of user-specific blocks.
SINAMICS DCC provides a convenient basis for resolving drive-
level open-loop and closed-loop control tasks directly in the con-
verter. This further extends the possibility of adapting SINAMICS
to the particular application. Local data processing in the drive
supports the implementation of modular machine concepts and
results in an increase in the overall machine performance.
