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. (Reading only)
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 switching the
power supply off starts the meas-
urement of the main circuit capaci-
tor life. When the Pr. 259 value is
"3" after powering on again, the
measuring is completed. Displays
the deterioration degree in Pr. 258.
Coasting to stop
When under voltage or power fail-
ure occurs, the inverter output is
shut off.
When under voltage or a power
failure occurs, the inverter can be
decelerated to a stop.
When under voltage or a power
failure occurs, the inverter can be
decelerated to a stop. If power is
restored during a power failure,
the inverter accelerates again.
