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 proprietary technological functions can be graphically configured in the SINAMICS drive system. In addition, local data processing in the drive supports the implementation of modular machine concepts and results in an increase in the overall machine performance. SINAMICS DCC is a part of the Advanced Technology Function, and is installed as an add-on to the STARTER commissioning tool.

SINAMICS DCC provides users with greater integral scope to adapt 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 and SINAMICS G150
• SINAMICS S120 and SINAMICS S150
• SINAMICS DCM and SINAMICS DCP
• SINAMICS GM150 and SINAMICS SM150
• SINAMICS GL150 and SINAMICS SL150

The user-friendly DCC editor enables easy graphics-based configuration, allows control loop structures to be clearly represented 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 graphically linked with one another by dragging and dropping. Test and diagnostic functions allow the program behavior to be verified 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 signals, all commonly used logic functions are available for selection (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.

SINAMICS DCC also offers the DCB Extension library from firmware version V4.6 and higher. This contains an extended range of blocks that is used as an additional, independent library in the DCC Editor. It includes the GMC and Math Extended library.
The GMC contains Motion Control blocks (GEAR, POSMC, CAMD, etc.).
With Math Extended, supplementary mathematical and logical function blocks (ASIN, ACOS, ATAN, LOG, etc.) are made available.
These libraries are ready for downloading along with application examples from the Siemens Application Support website.

Further information can be found in the Drive Applications section.

As well as the option of using the libraries made available by DCB Extension, DCB Extension proprietary libraries can also be created with custom-programmed blocks. These blocks and libraries are programmed with the separate SINAMICS DCB Studio development tool in the C/C++ high-level language and can be used as your own DCB Extension Library in the DCC editor. Use of these blocks as DCB extensions requires a runtime license.

The separate SINAMICS DCB Studio development tool is required for programming the blocks and generating the library as a DCB Extension.
