A-3
Life Alarm Output
The inverter can output an alarm by the self-diagnostic function when the service life of each consum-
able part incorporated in the inverter (main circuit capacitor, cooling fan, PC board electrolytic capaci-
tor) comes close to the end. Use this as a guide to know the time for the parts replacement.
Note that this alarm is output by the self-diagnosis based on the expected design life (not guaranteed
value). It has a margin of error depending on your environment or operation conditions.
For details, refer to 7-8-10 Capacitor Life Warning Signal (WAC) on page 7-96, 7-8-13 Cooling Fan
Life Warning Signal (WAF) on page 7-99, and 7-8-14 Lifetime Alarm (LIFE) on page 7-100.
