Auto Rstrt Tries

Was bedeutet F033 ?

The drive has exhausted its programmed number of automatic restart attempts (A541 [Auto Rstrt Tries]) after an initial fault, but the underlying fault condition persists. This indicates a recurring problem that the drive cannot self-clear, requiring manual intervention to diagnose and resolve the root cause.

• Recurring underlying fault (e.g., F004 UnderVoltage, F007 Motor Overload) that triggers repeatedly after each auto-restart attempt.
• Parameter A541 (Auto Rstrt Tries) set too low for an intermittent issue, causing the drive to quickly exhaust all restart attempts.
• Fault reset time (A542 [Auto Rstrt Time]) is too short, not allowing the system to stabilize before the next restart attempt.
• Persistent mechanical issue or process disturbance causing repeated tripping of the primary fault, making auto-restart ineffective.
• Inadequate troubleshooting and resolution of the initial fault, allowing it to reoccur after each restart.

1. 1

   Identify the *initial fault code* that occurred before F033 by checking the drive's fault history log (e.g., A500 [Last Fault], A501 [Fault 2]), as F033 is a secondary fault.

2. 2

   Thoroughly investigate and resolve the *root cause* of the recurring initial fault code (e.g., address voltage sags for F004, reduce mechanical load for F007).

3. 3

   Increase the number of automatic restart attempts (A541 [Auto Rstrt Tries]) to allow more recovery opportunities, but do not set it to an excessively high value.

4. 4

   Increase the fault reset time (A542 [Auto Rstrt Time]) to provide a longer delay between restart attempts, allowing system conditions to normalize.

5. 5

   Temporarily disable the automatic restart function (A541 [Auto Rstrt Tries] = 0) to force manual intervention and thorough fault diagnosis after each trip, preventing repeated restarts.
