4.2.67 Capacitor life warning signal (WAC)
The inverter checks the operating life of the capacitors on the internal
circuit boards on the basis of the internal temperature and cumulative
power-on time.
You can monitor the state of the capacitor life warning (WAC) signal by using the life-check monitoring function (d022).
If the WAC signal is output, you are recommended to replace the main circuit and logic circuit boards.

4.2.68 Communication line disconnection signal (NDc)
This signal function is enabled only when ModBus-RTU has been
selected for the RS485 communication.
If a reception timeout occurs, the inverter continues to output the
communication line disconnection signal until it receives the next data.
Specify the limit time for reception timeout by setting the communication trip time (C077).
For details, see Section 4.4, "Communication Functions."
