Error during phase regression

What does F405 mean?

The DIAX04 SSE-03VRS drive detected an unexpected regression in its communication phase (e.g., Sercos phases). This means the drive unexpectedly reverted to an earlier communication state, indicating a loss of stable communication. This is a critical error preventing coordinated motion and results in an immediate shutdown for safety.

• Sudden loss or degradation of the communication link (e.g., Sercos connection) to the DIAX04 SSE-03VRS drive.
• Master controller initiated an unexpected communication reset or phase regression.
• Faulty communication interface or hardware on the DIAX04 SSE-03VRS drive.
• Severe electrical noise or interference causing transient communication errors.
• Power instability affecting the communication module of the DIAX04 SSE-03VRS drive.

Click steps to track your progress.

1. 1

   Inspect the communication cable connecting the DIAX04 SSE-03VRS drive to the master controller for damage, looseness, or disconnections.

2. 2

   Verify the status and diagnostic logs of the master controller to see if it commanded a phase regression or experienced a fault itself.

3. 3

   Check for excessive electromagnetic interference in the control cabinet that might disrupt communication.

4. 4

   Perform a full power cycle of the DIAX04 SSE-03VRS system and the master controller.

5. 5

   If the problem continues, consider replacing the communication cable or checking the communication module on the DIAX04 SSE-03VRS drive for defects.
