Appendix-3 Life Alarm Output 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 4-90), or "Multi-function Output Terminal Contact Selection" (page 4-92) . 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. Appendix App-39
