6.1.2 To know the operating status at the occurrence of alarm
(Only when FR-PU04 is used)
When any alarm has occurred, the display automatically switches to the indication of
the corresponding protective function (error). By pressing the 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. It is also
possible to know the current in the same manner.
After resetting, you can confirm the definitions in "Alarm History". (For details, refer to
the instruction manual of the parameter unit (FR-PU04).)
6.1.3 Correspondences between digital and actual characters
