A00564

MMC Plugged During Operation

Siemens · SINAMICS G120 Variable Speed Drive

What does A00564 mean?

This alarm occurs when an MMC-PS (Multi Media Card) is inserted into the drive while it is operating, especially if no card was present at startup. This action can potentially corrupt the drive's current parameter dataset upon the next power cycle if automatic cloning at startup is enabled, leading to incorrect drive configuration.

Complete Troubleshooting Guide

  1. 1

    Immediately remove the MMC-PS card from the drive.

  2. 2

    If parameter corruption is suspected after a subsequent power cycle, re-upload known good parameters or perform a factory reset and reconfigure the drive.
