Calculate the remaining service life of the cooling fan, main circuit capacitor and on-block capacitor
based on the cumulative power on time, cumulative operation time, cumulative fan operation time,
the output current (inverter load factor) and the setting of f634 . An alarm will be monitor displayed
and sent out through output terminals when each component is approaching the time of replacement.
