SINAMICS Drive Control Chart (SINAMICS DCC) Siemens

Обзор

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 DCP
• SINAMICS GM150
• SINAMICS SM150
• SINAMICS GL150
• 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.

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 and blocks for supplementary mathematical and logical functions as a Math Extended library.

Using these blocks, it is possible to implement the following applications with SINAMICS DCC:

• Positioning
• 1:1 synchronous operation
• Gearing
• Gearing and positioning
• Camming
• Flying saws
• Cross cutters
• Calculation of trigonometric or logarithmic functions

These applications are available for downloading from 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 converter. 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.
