What does 34 mean?
This fault indicates that the drive has exceeded the configured number of auto-clear fault retries (P338 [AutoClrFlt Tries]) without successfully clearing a persistent fault while the drive was in a stopped state (provided P347 [Auto Retry Fault] bit 1 is set). This means automatic attempts to clear a fault have failed, and the drive remains non-ready, requiring manual diagnosis and correction of the original fault condition.
Additional Steps
Steps 1–2 are listed in Priority Fix.

Verify the configuration of P338 [AutoClrFlt Tries] and P347 [Auto Retry Fault] to ensure they are set appropriately for the application.
