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. It is also possible to know the current in the same manner. However, these values are not stored in
memory and are erased when the inverter is reset.
