5.1.2 To know the operating status at the occurrence of alarm
When any alarm has occurred, the display automatically switches to the indication of
the corresponding protective function (error). By pressing the
MODE
key at this point
without resetting the inverter, the display shows the output frequency. In this way, it is
possible to know the running frequency at the occurrence of the alarm. This also
applies to the current. After resetting, you can confirm the data in the alarm history
(refer to page 54).
