AuRsts Exhausted

Was bedeutet 33 ?

The drive has repeatedly attempted to automatically reset a fault and resume operation but has failed to clear the underlying condition within the programmed number of tries (P348 [Auto Rstrt Tries]). This indicates a persistent problem that the drive cannot self-correct, leaving it in a stopped state. Manual intervention is required to diagnose and fix the root cause of the original fault.

• A persistent underlying fault (e.g., Overcurrent, Overvoltage) that the auto-restart feature (P347 [Auto Rstrt Mode]) cannot clear.
• P348 (Auto Rstrt Tries) is set too low for the intermittent nature of the fault, exhausting retries prematurely.
• Immediate recurrence of the primary fault condition after each auto-restart attempt.
• Incorrect tuning of motor control parameters contributing to frequent, unresolvable fault trips.

1. 1

   1. Identify the *preceding* fault code from the drive's fault history (e.g., 'A1-00' for last fault) that triggered the auto-restart attempts.

2. 2

   2. Reset the drive manually to clear the 'AuRsts Exhausted' fault and observe for the recurrence of the primary fault.

3. 3

   3. Investigate and troubleshoot the primary fault code according to its specific causes and fix steps.

4. 4

   4. Temporarily disable auto-restart (P347 = 0) to prevent repeated, unsuccessful attempts and allow for focused troubleshooting.

5. 5

   5. If auto-restart is required, consider increasing P348 (Auto Rstrt Tries) or P349 (Auto Rstrt Delay) only after addressing the primary fault's root cause.
