A-2 Life Alarm Output
The inverter can output an alarm by the self-diagnostic function when the service life of each
consumable part incorporated in the inverter such as on-board smoothing capacitors and cooling fans
(except for the main circuit smoothing capacitor) comes close to the end. Use this as a guide to know
the time for the parts replacement.
For details, refer to Life Assessment Monitor [d022] on page 7-8, Capacitor Life Warning Signal (WAC)
on page 7-134 and Cooling Fan Life Warning Signal (WAF) on page 7-134.
Note that this alarm is output by the self-diagnostic function based on the expected design life, not
guaranteed value. It has a margin of error depending on your environment or operation conditions.
