Fault history

The parameter P1-13 archives the last four faults. Each fault is displayed in abbreviated form. The most recent fault is shown first (when calling P1-13). The oldest fault is deleted from the log.

The parameter P0-13 archives the last four faults along with a timestamp related to the inverter runtime P0-31. The timestamp is only visible in the LT Shell engineering software.

INFORMATION

If the last fault in the fault history is an undervoltage fault, no further undervoltage faults will be saved in the fault history. This is to prevent the fault history from being filled with undervoltage faults, which occur every time the inverter is switched off.
