Inverter parts life display

The degree of deterioration of the control circuit capacitor, main circuit capacitor, cooling fan, and
inrush current limit circuit can be diagnosed on the monitor.
When a part approaches the end of its life, a warning can be output by self diagnosis to prevent a
fault.
(Note that the life diagnosis of this function should be used as a guideline only, because with the
exception of the main circuit capacitor, the life values are theoretical calculations.)
In the life diagnosis of the main circuit capacitor, the alarm signal (Y90) is not output unless the
measurement method in (4) is performed.

Since repeated inrush currents at power ON will shorten the life of the converter circuit,
frequent starts and stops of the magnetic contactor must be avoided.

8.2 Inverter parts life display
Description
Displays whether or not the parts of the control
circuit capacitor, main circuit capacitor, cooling fan,
and inrush current limit circuit have reached the life
warning output level. Read-only.
Displays the deterioration degree of the inrush
current limit circuit. Read-only.
Displays the deterioration degree of the control
circuit capacitor. Read-only.
Displays the deterioration degree of the main
circuit capacitor. Read-only.
The value measured by E704 (Pr.259) is
displayed.
Setting "1" and turning the power supply OFF
starts the measurement of the main circuit
capacitor life.
If the setting value of E704 (Pr.259) becomes "3"
after turning the power supply ON again, it means
that the measurement is completed. The
deterioration degree is read to E703 (Pr.258).
