Siemens.mc.drives.acx.model.configuration Data.package May 2026

To understand the package, we must break down its nomenclature:

In practical terms, the Siemens.mc.drives.acx.model.configuration Data.package is the software blueprint that TIA Portal uses to translate human-readable settings (e.g., "Set speed to 1500 RPM") into low-level PROFIdrive telegrams, parameter indices, and cyclic data exchange.

The string Siemens.mc.drives.acx.model.configuration Data.package refers to a specific software component within the Siemens Startdrive engineering environment, which is integrated into the TIA Portal (Totally Integrated Automation). Overview of the Data Package

In the context of Siemens motion control (MC), this package serves as a container for configuration data required to model and parameterize SINAMICS drive units, such as the SINAMICS G120X or S120 series.

Namespace Identity: The "mc.drives" segment indicates its placement within the Motion Control Drives namespace, which is used for engineering and automation tasks like TIA Openness scripting. Siemens.mc.drives.acx.model.configuration Data.package

Role in Startdrive: It is a required software package for the Siemens SiePortal (formerly Industry Online Support) to properly recognize and configure specific drive hardware.

Functional Use: This package contains the metadata and object models that allow the TIA Portal to represent a physical drive as a digital object, enabling features like automatic configuration and parameterization. Core Components of Drive Configuration

When working with this configuration data, engineers typically interact with several key elements in the Siemens ecosystem:

Drive Objects (DO): The configuration data defines the drive's behavior as either a Servo or Vector control object.

CAx Data: This includes 3D models, EPLAN macros, and dimension drawings that are often bundled or referenced by these configuration packages for mechanical and electrical design.

Communication Telegrams: The package helps define how the drive communicates with a SIMATIC S7-1500 PLC, using standard or Siemens-specific telegrams like Telegram 103. To understand the package, we must break down

Hardware Description Files: It often works alongside GSDML files, which are necessary for the PLC to recognize the drive over PROFINET. Conclusion

In essence, the Siemens.mc.drives.acx.model.configuration Data.package is the digital DNA of a Siemens drive within the engineering software. It ensures that the SINAMICS hardware is accurately represented and fully functional within a TIA Portal project, allowing for seamless integration from initial design to commissioning. Required Software - Siemens SiePortal

This package is part of the "Advanced Commissioning eXtension" (ACX) framework for Siemens motion control (MC) drives. It serves as a container for configuration data that allows the engineering software to recognize, parameterize, and communicate with specific SINAMICS drive models (such as the G120 or S120 series).

Integration: It is an internal dependency of SINAMICS Startdrive, which is the software used to configure SINAMICS frequency converters within the TIA Portal.

Data Structure: The package contains the model definition and configuration data required to represent a physical drive unit as a digital object in a PLC project. Context of Use

Users typically encounter this specific string in technical error logs or software requirement lists when a TIA Portal project requires a version of Startdrive or a specific drive hardware support package (HSP) that is not currently installed on the workstation. In practical terms, the Siemens

Missing Package Issues: If this package is missing, the TIA Portal may be unable to open a hardware configuration that includes these specific drives, often prompting the user to download the corresponding Startdrive version or update.

Role in Motion Control: It ensures that the "Technology Objects" in the PLC (like speed-controlled or positioning axes) can correctly map their commands to the drive's internal parameters. Key Components

MC (Motion Control): Indicates the package's relevance to high-precision drive applications.

ACX: Likely stands for "Advanced Commissioning eXtension," a Siemens internal naming convention for drive integration modules.

PackageContainer: Refers to the file format (often a .pc5 or similar compressed format) that TIA Portal uses to distribute these model configurations.

If you are seeing an error regarding this package, ensure you have the latest version of SINAMICS Startdrive installed and that your Hardware Support Packages (HSPs) are up to date. Required Software - Siemens SiePortal
