Title Function
VI analog input break detection level
the analog data detected.
You can set the inverter so that it will calculate the remaining useful lives of the cooling fan, main
circuit capacitor and on-board capacitor from the ON time of the inverter, the operating time of the
motor, the output current (load factor) and the setting of  , and that it will display and send out
an alarm through output terminals when each component is approaching the time of replacement.

Display of part replacement alarm information
Part replacement alarm information (See page H-3) in the Status monitor mode allows you to check on
the time of replacement.
