Graphically configuring and expanding the device functionality using the freely available closed-loop control, arithmetic, and logic blocks
Drive Control Chart (DCC) extends the possibility of very simply configuring technological functions - both for the SIMOTION motion control system as well as for the SINAMICS DC MASTER drive system. For users, this opens up a new dimension regarding the adaptability of the systems mentioned to the specific functions of their machines. DCC has no restrictions with regard to the number of usable functions; this is only limited by the performance capability of the target platform.
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 pre-defined 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.
The block library encompasses 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, closed-loop PI controller, ramp function generator or wobble generator can be configured simply and easily.
Closed-loop control structures can be programmed with almost no restrictions in conjunction with the SIMOTION motion control system. These can then be combined with other program sections to form an overall program.
Further, Drive Control Chart for SINAMICS DC MASTER provides a user-friendly basis to handle drive-related 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.
Minimum hardware and software requirements
See the SCOUT or STARTER engineering software, since DCC is installed in addition to this.
Note:
In order to download the DCB library into the drive, it is necessary to use a memory card for the first time (option S01 or option S02 when using a Standard CUD right (option G10) or an Advanced CUD right (option G11)).
