An internal software error has occurred within the drive's operating system or application. This is a critical fault indicating a software anomaly that prevents normal operation and usually requires expert intervention to resolve. This can be caused by corrupted memory or an unexpected program state.
Click steps to track your progress.
Perform a power cycle of the drive by disconnecting input power for 60 seconds.
Upload the drive's current parameter configuration (e.g., using a backup tool or software).
Attempt a full factory reset of the drive parameters (e.g., P0-10 = 1, then P0-10 = 0 to restore defaults).
Re-install the drive's firmware package, ensuring the correct version for the hardware model.
Reload the saved parameter configuration to the drive after firmware re-installation.
Monitor internal processor load (e.g., monitoring parameter P1-50, if available) after reboot.
