Phase switching without ready signal

What does F406 mean?

The DIAX04 SSE-03VRS drive attempted a communication phase switch (e.g., Sercos) without receiving the necessary 'ready' signal from the master controller or another network component. This indicates a synchronization or handshake failure, preventing the network from achieving a stable operational state. The drive faults to maintain communication integrity.

• Master controller failed to send the 'ready' signal at the appropriate time during phase switching.
• Delay or loss of the 'ready' signal due to communication link issues (e.g., damaged cable, network congestion).
• DIAX04 SSE-03VRS drive's communication interface is faulty, not detecting the 'ready' signal correctly.
• Incorrect timing parameters or synchronization settings (e.g., S-0-0014) between the master and slave.
• Firmware incompatibility or bug affecting communication handshakes.

Click steps to track your progress.

1. 1

   Verify the communication configuration and timing parameters on both the master controller and the DIAX04 SSE-03VRS drive, focusing on phase switching and ready signals.

2. 2

   Inspect the communication cable (e.g., Sercos fiber optic) for any physical damage or poor connections.

3. 3

   Check the diagnostic status of the master controller to confirm it is sending the 'ready' signal as expected.

4. 4

   Ensure proper termination and absence of excessive electromagnetic interference on the communication network.

5. 5

   Perform a full power cycle of the entire DIAX04 SSE-03VRS system and the master controller. If the fault persists, consider a faulty communication interface.
