PROFIBUS: fatal SW error

Hva betyr A00706 ?

A fatal software error has occurred within the PROFIBUS communication module, potentially related to hardware checks, general communication issues, or problems with the V1SL stack. This critical error can lead to a complete loss of PROFIBUS connectivity and drive control, rendering the system inoperable via PROFIBUS.

• Corrupted PROFIBUS GSD file loaded into the master (e.g., PLC) causing incompatible communication settings for the drive.
• Firmware bug within the drive's PROFIBUS communication board (CB) requiring an update to a stable version.
• Internal hardware fault on the PROFIBUS communication board preventing proper initialization or consistent operation.
• Severe electromagnetic interference (EMI) causing data corruption during the communication module's initialization phase.
• Incompatible PROFIBUS master or specific configuration attempting unsupported functions, leading to internal software errors.

1. 1

   1. Power cycle the drive by disconnecting and reconnecting the main supply voltage, then observe if the fault clears upon restart.

2. 2

   2. Verify the PROFIBUS GSD file used in the master's hardware configuration is the correct and latest version for the drive's firmware revision.

3. 3

   3. Update the drive's firmware to the latest available version, especially if known bugs related to PROFIBUS communication are documented.

4. 4

   4. Test the drive with a known-good PROFIBUS communication board (CB) if available, to rule out a hardware fault on the existing board.

5. 5

   5. Temporarily disconnect the PROFIBUS cable from the X100 terminal and restart the drive to see if the fault persists, which helps isolate bus issues from internal hardware.
