5.4.16 Inverter parts life display
The degree of deterioration of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit, and
relay contacts of terminals A, B, and C can be diagnosed on the monitor.
When a part approaches the end of its life, an alarm 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.)

Setting range
*1 Displays whether or not the parts of the control
(0 to 255)
circuit capacitor, main circuit capacitor, cooling fan,
and inrush current limit circuit have reached the life
alarm output level. Read-only.
(0 to 100%) Displays the deterioration degree of the inrush
current limit circuit. Read-only.
(0 to 100%) Displays the deterioration degree of the control
circuit capacitor. Read-only.
(0 to 100%) Displays the deterioration degree of the main
circuit capacitor. Read-only.
The value measured by Pr.259 is displayed.
0, 1(2, 3, 8, 9) Setting "1" and turning the power supply OFF
starts the measurement of the main circuit
capacitor life.
If the setting value of Pr.259 becomes "3" after
turning the power supply ON again, it means that
the measurement is completed. The deterioration
degree is read to Pr.258.
11(12, 13, 18, When "11" is set, turning OFF the power supply
19) starts the measurement of the main circuit
capacitor life.
If the setting value of Pr.259 becomes "13" after
turning the power supply ON again, it means that
the measurement is completed. The degree of
deterioration is read to Pr.258.
(0 to 100%) Displays the estimated residual life of the main
circuit capacitor. Read-only.
0 to 100% Displays the degree of deterioration of the relay
contacts of terminals A1, B1, and C1.
0 to 100% Displays the degree of deterioration of the relay
contacts of terminals A2, B2, and C2.
