fan, and each parts of the inrush current
limit circuit has reached the life alarm
output level or not. (Reading only)
Displays the deterioration degree of the
inrush current limit circuit. (Reading only)
Displays the deterioration degree of the
control circuit capacitor. (Reading only)
Displays the deterioration degree of the
main circuit capacitor. (Reading only)
The value measured by Pr. 259 is
displayed.
Setting "1" and switching the power supply
OFF starts the measurement of the main
circuit capacitor life.
0, 1
When the Pr. 259 value is "3" after
powering ON again, the measuring is
completed.
Displays the deterioration degree in Pr. 258.
