Root Cause Summary

SIEMENS alarm 100363 occurs when a servo drive password has been modified and requires user confirmation before the system can proceed with servo operations. This is a security feature in SINUMERIK systems to prevent unauthorized changes to critical servo parameters.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Access servo diagnostics

    Navigate to Diagnostics > Hardware > Drives in the HMI to view current servo drive status and password requirements.

    Check the drive status display for any password-related indicators before proceeding.

  2. 2

    Confirm new password

    Go to Commissioning > Drive > Password and enter the new password twice to confirm the change. Use parameter P0010 to set the drive to commissioning mode if needed.

    Ensure you have the correct new password before attempting confirmation to avoid lockout.

  3. 3

    Reset drive communication

    Execute a drive reset using parameter P0970 = 1 or through HMI Diagnostics > Hardware > Drives > Reset to clear the password confirmation requirement.

    Monitor parameter r0002 (drive status word) to verify successful password acceptance.
