Fault at DRIVE-CLiQ socket X100

Siemens · SINAMICS S120/S150 Reference List

What does F40000 mean?

A general fault has been detected at the drive object connected to the DRIVE-CLiQ socket X100. The fault value (r0949) provides information about the specific underlying fault that first occurred for this drive object. This fault requires immediate acknowledgment.

Common Causes

  • Disruption or damage to the DRIVE-CLiQ cable connected to socket X100 (e.g., bending, crushing, EMI).
  • Malfunction or power loss of the DRIVE-CLiQ component connected to X100 (e.g., motor module, sensor module, encoder).
  • Incorrect or unstable DRIVE-CLiQ communication due to network configuration issues or corrupted data packets.
  • Hardware defect in the DRIVE-CLiQ interface of the main Control Unit or the connected component at X100.
  • Drive-CLiQ component connected to X100 reports its own internal fault, which is then propagated as F40000.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    1. Examine the DRIVE-CLiQ fault value r0949 to identify the specific error code reported by the device connected to X100.

  2. 2

    2. Inspect the DRIVE-CLiQ cable connected to socket X100 for any physical damage, kinks, or stress points.

  3. 3

    3. Verify that the DRIVE-CLiQ component connected to X100 is properly powered and its status LEDs indicate normal operation.

  4. 4

    4. Reseat the DRIVE-CLiQ cable connector at both socket X100 and the connected component to ensure secure contact.

  5. 5

    5. Swap the DRIVE-CLiQ cable connected to X100 with a known good cable of the same type and length.

  6. 6

    6. Perform a DRIVE-CLiQ topology scan (e.g., using STARTER/SCOUT) to confirm all connected components are detected and configured correctly.
