System fault

What does 8 mean?

A general system fault has occurred, indicating a possible component failure or faulty operation within the frequency converter. When this fault appears, it is crucial to consult the fault history for a specific subcode (Id xxx) to pinpoint the exact nature of the internal issue (e.g., Watchdog reset, SW stack overflow, HW stack overflow, Misalignment, Illegal op, PLL lost lock / Low CPU voltage, EEPROM Device, EEPROM Queue full, MPI communication dead or CRC errors, CPU load).

• General internal system error requiring diagnostics.
• Power supply fluctuations beyond specified limits.
• Communication loss between internal modules.
• Software execution error or crash.
• Parameter configuration error.

1. 1

   Reset the fault and restart the frequency converter.

2. 2

   Access the Fault History menu (F6.x) on the API and locate the subcode (Id xxx) associated with the F8 fault to gather more diagnostic information.
