PROTECTIVE FUNCTIONS
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
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).
5.1.3 Correspondence between digital and actual characters
There are the following correspondences between the actual alphanumeric characters
and the digital characters displayed on the operation panel (FR-PA02
-02
):
5.1.4 Resetting the inverter
The inverter can be reset by performing any of the following operations. Note that the
electronic overcurrent protection's internal heat calculation value and the number of
retries are cleared (erased) by resetting the inverter.

Operation 1: ............Using the operation panel (FR-PA02-02), press the key to
reset the inverter. (This may only be performed when the inverter
protective function (major fault) is activated.)
