Configuration vector for the drive failed

What does F00350 mean?

The drive failed to validate its configuration vector (SZL vector) during startup, indicating a mismatch between the programmed configuration and the actual hardware, or an internal data integrity issue. This critical fault prevents the drive from starting and operating, potentially due to incorrect power modules or IO boards.

• Control unit (e.g., CU250S-2) firmware version mismatch with the loaded parameter set or the expected hardware configuration.
• Corrupted parameter set (e.g., `_config.xml` file) on the MMC card or in the drive's internal memory.
• Hardware changes (e.g., replacement of communication module, power unit) without a proper drive configuration update.
• MMC card data corruption or a faulty MMC card itself, leading to invalid configuration data.
• Internal memory (RAM/ROM) fault on the control unit preventing proper configuration loading or validation.

Click steps to track your progress.

1. 1

   1. Perform a power cycle of the drive and re-evaluate if the fault persists, as it might be a transient data error.

2. 2

   2. Ensure the firmware version of the control unit matches the version used to create the loaded parameter set in STARTER/TIA Portal.

3. 3

   3. Back up the current parameters (if possible), then perform a factory reset (P0010=30, P0970=1) and reload a known good parameter set.

4. 4

   4. Power down the drive, then carefully re-insert or replace the MMC card, ensuring it is securely seated and contains a valid parameter set.

5. 5

   5. Use STARTER or TIA Portal to upload the current configuration from the drive and compare it to an offline project for discrepancies.

6. 6

   6. Consider replacing the control unit (e.g., CU250S-2 PN) if all other steps fail and the issue points to an internal hardware defect.
