Assign the output terminal function 029 [WAC] capacitor life prewarning signal to one of [CC-01] to
[CC-07] that corresponds to the output terminal and output the signal.
The life spans of the capacitors on the circuit board are diagnosed from the temperature inside the
inverter and the energized time.
The state of this signal can be monitored by using the life diagnostic monitor. Refer to 5-9 Life Monitor
on page 5-17.
A warning will also be displayed in the display icons on the LCD operator.
Precautions for Correct Use
You are recommended to replace or repair the inverter when a warning about capacitor lives is
generated.
 Parameter
This signal will be output when the rotation speed of the inverter’s built-in cooling fan decreases to 75%
or less.
Assign the output terminal function 030 [WAF] cooling fan rotation speed reduction signal to one of
[CC-01] to [CC-07] that corresponds to the output terminal and output the signal.
The signal is output when it is detected that the rotation speed of the cooling fan incorporated in the
inverter has decreased to 75% or less.
The state of this signal can be monitored by using the life diagnostic monitor. Refer to 5-9 Life Monitor
on page 5-17.
A warning will also be displayed in the display icons on the LCD operator.
Precautions for Correct Use
• Check the cooling fan for clogging when this signal is output.
• When the Cooling Fan Operation (bA-70) is set to 01 (Enabled during RUN (including 3 min-
utes after power on/stop), this signal will not be output while the fan is stopped.
