7-8-12 Capacitor Life Warning Signal (WAC)

Use this signal to determines the life expectancy of the capacitor on the option board based on the
inverter's internal temperature and conduction time.
The status of this signal can be monitored in the Life Assessment Monitor (d022).
Set this function according to A-2 Smoothing Capacitor Life Curve on page A-7.

Cooling Fan Operation

b093 Total Fan Operation Time Clear
Note 1. If a momentary power interruption or power shutoff occurs when the cooling fan is operating, the cooling
fan will stop temporarily and, after power recovery, restart automatically.
2. Clear the total operation time only when you replace the cooling fan. Otherwise, the Life Assessment
Monitor (d022) will not display correct monitor data.
