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, 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, the life values are theoretical
calculations.)
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.
•
Pr.255 Life alarm status display
and the Life alarm (Y90) signal can be used to check whether or not the life alarm output
level is reached for the following parts: the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit
circuit, relay contacts of terminals A, B, and C, inverter module, or control circuit board.

(0 to 879)
Displays whether or not the life alarm output level is
reached for the following parts: the control circuit
capacitor, main circuit capacitor, cooling fan, inrush
current limit circuit, relay contacts of terminals A, B, and
C, inverter module, and control circuit board. Read-
only.

Main circuit capacitor life
measuring
0
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
.

Displays the estimated residual life of the main circuit
capacitor. Read-only.
