6.12 Engineering Software Drive Control Chart (DCC)
Graphical configuring and expansion of the device functionality by means of available closed-loop
control, arithmetic, and logic function blocks
Drive Control Chart (DCC) expands the facility for the simplest possible configuring of
technological functions for both the SIMOTION motion control system and the SINAMICS
drive system. This provides the user with a new dimension of system adaptability for specific
machine functions.
DCC does not restrict the number of functions that can be used; the only restriction is the
performance of the target platform.
The user-friendly DCC Editor enables easy graphical configuration and a clear
representation of control loop structures as well as a high degree of reusability of existing
diagrams.
The open-loop and closed-loop control functionality is defined by using multi-instance-
enabled blocks (Drive Control Blocks (DCBs)) from a pre-defined library (DCB library) that
are selected and graphically linked by dragging and dropping.
Test and diagnostic functions allow verification of the program behavior, and troubleshooting
in the event of a fault.
The block library encompasses a large selection of closed-loop, arithmetic and logic function
blocks, as well as comprehensive open-loop and closed-loop control functions.
For combining, analyzing and acquiring binary signals, all commonly used logic functions are
available for selection (AND, XOR, on/off delay, RS flipflop, counter, etc.). Numerous
computation functions are available for monitoring and evaluating numerical variables; for
example absolute value generation, division, min/max evaluation.
Besides drive control functions, it is also a simple matter to configure axis winding functions,
PI controllers, ramp-function generators, and wobble generators.
Almost unlimited programming of control structures is possible in conjunction with the
SIMOTION motion control system. These can then be combined with other program sections
to form an overall program.
Drive Control Chart for SINAMICS also provides a convenient basis for resolving drive-level
open-loop and closed-loop control tasks directly in the drive. This results in further
adaptability of SINAMICS for the task set. On-site processing in the drive supports modular
machine concepts and results in increased overall machine performance.
Note
A detailed description of the DCC Editor and the available Drive Control Blocks is given in
the relevant documentation. This documentation is available on the accompanying customer
DVD.
