Chapter 4 Explanation of Functions<br />
4.1.19 Life-check monitoring<br />
When the life-check monitoring function (d002) is selected, the inverter<br />
displays the operating life status of two inverter parts output from<br />
corresponding intelligent output terminals by using LED segments of the<br />
monitor.<br />
The two targets of life-check monitoring are:<br />
1: Life of the capacitor on the main circuit board<br />
2: Degradation of cooling fan speed<br />

d022: Life-check monitoring<br />
Life check<br />
Normal<br />
Note 1: The inverter estimates the capacitor life every 10 minutes. If you turn the inverter power on and off<br />
repeatedly at intervals of less than 10 minutes, the capacitor life cannot be checked correctly.<br />
Note 2: If you have specified "01" for the selection of cooling fan operation (function "b0092"), the inverter<br />
determines the cooling fan speed to be normal while the cooling fan is stopped.<br />
