SINAMICS DriveSim Basic
https://support.industry.siemens.com/cs/document/109798225/
SINAMICS DriveSim Basic provides easy-to-use models for PROFIdrive-enabled SINAMICS drives, so you can făcute a digital twin of your drive.
As an OEM, how can you verify and validate the communication between the drive and the PLC already in the planning phase? And how can you ensure that the drives and motors you selected fit your application?
With SINAMICS DriveSim Basic, you can answer these questions already at the estetică and planning stage.
Context
SINAMICS DriveSim Basic provides easy-to-use models for PROFIdrive-enabled SINAMICS drives, so you can create a digital twin of your drive.
The models are validated and tested against real SINAMICS drives and are available in the form of a standardized FMU (Functional Mockup Unit). Therefore, they are compatible with various standard time-based simulation programs such as SIMIT, Simcenter Amesim, NX Motion or Matlab Simulink.
SINAMICS DriveSim Basic is another element in your engineering toolbox. Together with other virtual SIEMENS solutions, e.g. SIMATIC S7-PLCSIM Advanced or NX Mechatronics Concept Designer, a consistent model-based development process can be implemented.
Customer benefits of SINAMICS DriveSim Basic:
Speed up time-to-market for OEMs
Test validated SINAMICS models under real conditions at the stil or planning stage and make needed adjustments
Identify issues and improvement capabilities early in the design stage and reduce testing effort to save time and cost
Model Content
SINAMICS DriveSim Basic implements specific functionality subsets and the minimum required parameters of the converter control. In contrast to a real device, functional groups implemented in the digital twin can be tailored as a whole to a specific use case :
PROFIdrive communication (telegrams 1, 2, 3, 4, 5, 6, 20, 102, 103, 105, 106, 352, 750)
Sequence control (sequencer)
Setpoint channel (basic ramp-function generator)
Encoder
Speed controller (incl. Reference Model, Torque Limiting and Windup-Control)
Current Setpoint Filter (Band-Stop filter)
Position Control via PLC with Dynamic Servo Control (DSC, SERVO only)
Besides the functionality implemented by the control model, SINAMICS DriveSim Basic offers
a simplified representation of the electrical system (motor, converter…) as a closed current control loop and
an optional internal feedback loop of speed / torque via an internal load tip (direct feedthrough or configurable two-mass-oscillator, linear and squared characteristics).
SINAMICS DriveSim Basic is valid for the following SINAMICS devices and firmware versions:
Differentiation
The well-established solution of generic SIMIT library PROFIdrive for drives and the Drives behavior library (see entry 10976100) can be enhanced or even replaced by SINAMICS DriveSim Basic with a more detailed SINAMICS drive model. The following table gives an overview of the main differences (comparison based on function level of SINAMICS S120 and SIMIT):
Advantages of SINAMICS DriveSim Basic compared to SIMIT PROFIdrive blocks:
Increased level of detail due to speed controller, current setpoint filters and internal load model
Identical parameter values and meaning as in the real SINAMICS device
Direct reference to SINAMICS documentation
Validated against the real SINAMICS drive
No wiring effort to represent functional configurations
Significant reduction of SIMIT simulation tags (even more is possible if unused in-/ outputs are deselected within the Component Type Editor (CTE)
Enables simulation of an (internal) two-mass oscillator as application with realistic SINAMICS parameter settings, besides the known limitations by the minimum sample time in SIMIT
Compatible with every FMU Co-Simulation 2.0 compatible simulation tool
On the other hand, it may happen that with many drives in an overall model, due to the overhead of the FMU interface, the FMU requires more computing performance than a comparable tool-native (here SIMIT-native) implementation.
Use Cases
With SINAMICS DriveSim Basic, you can implement two major use cases:
Virtual PLC commissioning
Calculation of load profiles for drive sizing
Use case 1: Virtual PLC commissioning
If you are designing a machine, you want to make sure the PLC code works with your SINAMICS drive. After writing the PLC code in TIA Portal, you can connect it via PLCSIM Advanced to any time-based simulation tool (e.g. SIMIT). Integrated in your simulation tool, SINAMICS DriveSim Basic acts as a realistic communication partner for the PLC. Next, you can commission the virtual PLC in TIA Portal as you would do with a real PLC connected to a real drive. Optionally, you can connect a simulation tool such as NX Mechatronic Concept Designer to visualize the mechanical movements.
Use case 2: Providing load characteristics for drive sizing
If you are designing a machine, you want to make sure that you select the SINAMICS converter and SIMOTICS motor most suitable for you drive application. As SINAMICS DriveSim Basic is control-unit-agnostic and thus represents a generic drive, you can parametrize it according to the functionality of your application. Running the simulation results in load characteristics, i.e. torque or speed curves over time. You can import these load profiles into TIA Selection Tool to select the suitable Control Unit and dimension the drive to best fit to the demand. It is recommended to refine the simulation model according to the inertia provided by TIA Selection Tool and repeat simulating and dimensioning the drive until the provided inertia is stable. Optionally, you can connect a simulation tool such as NX Mechatronic
Concept Designer to visualize the mechanical movements.
