CB configuration error

What does A00711 mean?

The Communication Board (CB) has reported an internal configuration error. This suggests that the parameters or settings for the CB are incorrect or inconsistent, preventing it from functioning as intended and disrupting communication capabilities, hindering proper integration into the control system.

• Parameterization data stored on the CB (e.g., via STARTER or BOP) is corrupted or incompatible with the drive's main firmware.
• Incorrect drive type or firmware version selected when configuring the CB in the engineering software (e.g., TIA Portal, STARTER).
• Internal memory fault on the communication board preventing it from loading or retaining correct configuration settings.
• Firmware mismatch between the main control unit and the communication board (CB) itself, leading to incompatible operations.
• Power supply instability to the communication board during configuration loading, causing data corruption.

Click steps to track your progress.

1. 1

   1. Perform a factory reset of the communication board (CB) parameters through the drive's HMI or engineering software (e.g., use P0970 for a general reset).

2. 2

   2. Reload the communication board's configuration using the engineering software (e.g., STARTER), ensuring the correct drive type and firmware version are selected.

3. 3

   3. Update the firmware of both the main drive unit and the communication board (CB) to the latest compatible versions.

4. 4

   4. Verify the power supply voltage to the drive is stable and within specified limits, checking terminals L1, L2, L3 for fluctuations.

5. 5

   5. If the issue persists, replace the communication board (CB) with a known-good unit, as it may indicate an internal hardware fault.
