Appendix-3 Life Alarm Output
•When the product life becomes close to the end for the parts including the on-board smoothing
capacitor or cooling fan, but excluding the main circuit smoothing capacitor, an alarm can be output
through the self-diagnostic function. Use it as a reference of the parts replacement period.
For details, refer to
"Life Assessment Monitor [d022]" (page 4-5), "Multi-function Pulse Counter (PCNT,
PCC)" (page 4-94), or
"Multi-function Output Terminal Contact Selection" (page 4-96).
This alarm is output through the self-diagnosis based on the expected design life (not a guaranteed
value). Therefore, it has a margin of error depending on your environment or operation conditions.
