For advanced users, you can create custom .ACX files, for example, to run drive macros. This is a powerful but advanced feature. The file must be created according to the ACX macro definition and saved in the appropriate directory on the drive's non-volatile memory.

: Software like Startdrive or Drive Monitor transfers the container via Ethernet (PROFINET) directly to the drive's memory card (Control Unit).

By downloading this as a single "package container," the engineering system ensures that partial or corrupted configurations are never deployed. The drive receives the container, validates its cryptographic signature or checksum, unpacks it internally, and applies the changes atomically. 3. Where is this Component Encountered?

The configuration package download was interrupted.

: Large configuration packages downloaded over unstable Wi-Fi or heavily congested industrial networks can experience packet drop. Always use a dedicated, wired PROFINET/Ethernet connection for drive commissioning.

The of the Siemens drive you are configuring

Download the latest firmware for your ACX-based drive (e.g., S210) from the Siemens Industry Online Support (SIOS) portal. 2. Reset the Drive to Factory Settings If the internal model container is stuck or corrupted: Perform a Factory Reset via the Web Server or TIA Portal. Power cycle the drive (DC link and 24V supply). Attempt the download again. 3. Clear Browser Cache (If using Web Server) If you are commissioning via a web browser: Clear your browser's cache and cookies .

This is the most reliable and commonly successful approach, as Startdrive automatically installs all necessary runtime libraries, including the PackageContainer component:

: The "ACX" in the package name refers to the internal drive model architecture used by Siemens for SINAMICS S-series and G-series drives within the TIA environment.

: It provides the "model" or definition that the TIA Portal uses to understand a drive's parameters, communication telegrams (like Telegram 352), and physical interfaces. Missing Package Error

Before a new drive model can be configured in an engineering environment like TIA Portal, the software's hardware catalog must be updated. This is often completed via the TIA Administrator or direct downloads from the Siemens Industry Online Support (SIOS) portal. The ACX container serves as the payload that introduces new drive definitions to the local database. 2. Project Compilation

Without the correct PackageContainer installed, your engineering software cannot process these files, leading to the errors described below.
