PARAMETERS
4.21.2 Display of the life of the inverter parts (Pr. 255 to Pr .259)
(1) Life alarm display and signal outuput (Y90 signal, Pr. 255)
⋅ Whether any of the control circuit capacitor, main circuit capacitor, cooling fan and inrush current limit circuit has reached
the life alarm output level or not can be checked by Pr. 255 Life alarm status display and life alarm signal (Y90).
Degrees of deterioration of main circuit capacitor, control circuit capacitor, cooling fan and inrush current limit
circuit can be diagnosed by monitor.
When any part has approached the end of its life, an alarm can be output by self diagnosis to prevent a fault.
(Use the life check of this function as a guideline since the life except the main circuit capacitor is calculated
theoretically.)
For the life check of the main circuit capacitor, the alarm signal (Y90) will not be output if a measuring method of
(4) is not performed.
Parameter

Setting "1" and switching the power supply off
starts the measurement of the main circuit
capacitor life.
When the Pr. 259 value is "3" after powering on
again, the measuring is completed. Read the
deterioration degree in Pr. 258.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 156.)
