Display whether the control circuit
capacitor, main circuit capacitor,
cooling fan, and each parts of the
inrush current limit circuit has
reached the life alarm output level
or not.
Display the deterioration degree of
the inrush current limit circuit.
(Reading only)
Display the deterioration degree of
the control circuit capacitor.
(Reading only)
Display the deterioration degree of
the main circuit capacitor.
(Reading only)
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.
When the Pr. 259 value is "3" after
powering on again, the measuring
is completed. Read the deteriora-
tion degree in Pr. 258.
