5.4.19 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.)

*1 The setting range (read-only) differs depending on the inverter model (standard model, separate converter type, or IP55 compatible model).
*2 The setting is available only for standard models and IP55 compatible models.
 Life alarm display and signal output (Y90 signal, Pr.255)
• In the life diagnosis of the main circuit capacitor, the Life alarm (Y90) signal is not output unless measurement by turning OFF
the power supply is performed.
• Whether or not the parts of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit,
internal air circulation fans, or relay contacts of terminals A, B, and C have reached the life alarm output level can be
checked with Pr.255 Life alarm status display and the Life alarm (Y90) signal. (Internal air circulation fans are equipped
with IP55 compatible models.)

(0% to 100%)
The value measured by Pr.259 is displayed.
Setting "1" and turning the power supply OFF starts the
measurement of the main circuit capacitor life.
0, 1 If the setting value of Pr.259 becomes "3" after turning
(2, 3, 8, 9) the power supply ON again, it means that the
measurement is completed. The deterioration degree is
read to Pr.258.
When "11" is set, turning OFF the power supply starts
the measurement of the main circuit capacitor life.
11 If the setting value of Pr.259 becomes "13" after turning
(12, 13, 18, 19) the power supply ON again, it means that the
measurement is completed. The degree of
deterioration is read to Pr.258.
