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.

Complete Troubleshooting Guide

1. 1

   If r0949 = 13, ensure that the correct power module is fitted to the inverter control unit and is compatible with the firmware.

2. 2

   If r0949 > 1000, verify that the correct IO Board is installed and properly seated.

3. 3

   For other internal failure codes (r0949 = 1, 2, 11, 12), contact Siemens Service Department as these are typically unrecoverable by field technicians.

4. 4

   Perform a power cycle of the drive, as this fault requires it for acknowledgment.
