Maximum allowed troubles exceeded

Hva betyr 25233 ?

The number of permitted restart attempts after a fault, configured in parameter 0x2839:003 (P760.03), has been exceeded. This indicates that faults have occurred too frequently and could not be reset automatically. The motor will remain at a standstill, and no automatic restart will be executed.

• Repetitive occurrence of an underlying fault (e.g., overcurrent, motor overload) that the drive attempts to clear automatically.
• The number of allowed automatic restart attempts, configured in Parameter 0x2839:003 (P760.03), is set too low for operational transients.
• Intermittent external conditions (e.g., supply voltage sags, brief mechanical jams) frequently triggering minor faults.
• A persistent issue in the mechanical system causing repeated load spikes that exceed drive limits.
• Underlying hardware degradation in the drive itself, leading to sporadic and unresolvable faults.

1. 1

   Access the drive's fault history log to identify the specific, frequently recurring fault codes that precede this warning.

2. 2

   Diagnose and resolve the root cause of the most common preceding fault (e.g., motor parameters, mechanical binding, power supply issues).

3. 3

   Evaluate the application's operational transients and consider increasing the value of Parameter 0x2839:003 (P760.03) if appropriate.

4. 4

   Monitor the system's operational parameters (e.g., motor current, DC bus voltage) during fault events to pinpoint specific conditions.

5. 5

   Inspect power connections and control wiring for loose terminals or signs of wear that could cause intermittent faults.
