Failure of 2 consecutive MDT signals
Indramat · DIAX 04
Was bedeutet F402 ?
The DIAX04 SSE-03VRS drive failed to receive two consecutive Master Data Telegrams (MDT) from the master controller. The MDT carries critical command and data information. This is a communication breakdown, indicating that the drive is not receiving necessary instructions, leading to an immediate shutdown to prevent uncontrolled operation.
Häufige Ursachen
- Interruption or severe degradation of the real-time communication link (e.g., Sercos) to the DIAX04 SSE-03VRS drive.
- Master controller experiencing issues transmitting MDTs or is temporarily halted.
- Faulty communication interface or hardware on the DIAX04 SSE-03VRS drive.
- Incorrect network configuration or timing parameters (e.g., S-0-0012) causing data loss.
- Excessive electromagnetic interference impacting communication signal integrity.
Reparaturschritte & Checkliste
Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.
- 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
Verify the status of the master controller and ensure it is actively transmitting MDTs. Check its diagnostic logs.
- 3
Check communication ring integrity (if applicable) for breaks or faulty nodes. Bypass or isolate sections to identify the problematic segment.
- 4
Review and verify communication parameters (e.g., S-0-0012, S-0-0013) in the DIAX04 SSE-03VRS drive and the master controller for consistency.
- 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.
