18.3.2 Checking retry information
• Want to see the information of the moment of error
occurrence because a retry was executed after the
inverter generated the error.
• The last 9 retry histories are displayed.
• The latest retry history is displayed on the retry
monitor 1.
• The following data items are displayed on the
monitor:
1) Error factor for retry
2) Output frequency (Hz) at retry
3) Output current (A) at retry
4) Main circuit DC voltage (V) at retry
5) Operation state at retry
6) Cumulative inverter operating time (h) before retry
7) Cumulative inverter power-on time (h) before retry

Parameter
 “Detailed monitor 2” for checking the history
• You can look through the history
with the arrow keys.
• While a retry is underway, the inverter tries to
continue running. For a trip after a retry, the trip
information is recorded on the trip history.
• The information of the moment of error occurrence
may not be fetched properly if the inverter is
forcibly turned OFF by its hardware.
• For a momentary overcurrent event, the current
may be recorded in a value lower than the actual
value.
