Double MST failure shutdown

Hva betyr F401 ?

The DIAX04 SSE-03VRS drive detected a double failure of the Master Synchronization Telegram (MST) within its real-time communication network (e.g., Sercos). This means the drive has lost synchronization with the master controller twice consecutively. This is a critical communication fault that results in immediate shutdown to prevent uncoordinated and potentially dangerous movements.

• Repeated interruptions or severe degradation of the real-time communication link (e.g., fiber optic cable, Sercos ring) to the DIAX04 SSE-03VRS drive.
• Master controller experiencing issues generating or transmitting the MST.
• Faulty communication interface or hardware on the DIAX04 SSE-03VRS drive.
• Incorrect network configuration or timing parameters (e.g., S-0-0010) causing synchronization loss.
• Excessive electromagnetic interference impacting communication signal integrity.

1. 1

   Inspect the communication cable (e.g., fiber optic, Ethernet) connecting the DIAX04 SSE-03VRS drive to the master controller. Check for physical damage, proper termination, and secure connections.

2. 2

   Verify the status of the master controller's communication interface and its ability to transmit MSTs.

3. 3

   Check communication ring integrity (if applicable) for breaks or faulty nodes. Bypass or isolate sections to identify the problematic segment.

4. 4

   Review and verify communication parameters (e.g., S-0-0010, S-0-0011) in the DIAX04 SSE-03VRS drive and the master controller for consistency.

5. 5

   Monitor communication diagnostic indicators on both the master and the DIAX04 SSE-03VRS. If the fault persists, consider a faulty communication interface on the drive.
