7 Detailed Functions
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 the Multi-function Output P1 to P5 Selection (C021 to C025) or Multi-function Relay Output (MA,
MB) Function Selection (C026) to 39 (WAC) to allocate the desired signal.
Parameter No.
C021 to C025
C026
Cooling Fan Life Warning Signal (WAF)
• This signal will be output when the rotation speed of the inverter's built-in cooling fan decreases to
75% or less.
• Set the Multi-function Output P1 to P5 Selection (C021 to C025) or Multi-function Relay Output (MA,
MB) Function Selection (C026) to 40 (WAF) to allocate the desired signal.
• When the Cooling Fan Operation (b092) is set to 01 (Enabled only during RUN (including 5 minutes
after power on/stop)), this signal will not be output while the fan is stopped.
• If this signal is output, check the cooling fan for clogging etc.
• The status of this signal can be monitored in the Life Assessment Monitor (d022).
