4-6-23 Lifetime Warning Output Function
Capacitor life warning signal – The inverter checks the operating life of the
capacitors on the internal circuit board on the basis of the internal tempera-
ture and cumulative power on time. You can also monitor the state of the
capacitor life warning signal (WAF) in
d022. If the WAC signal is given out, it is
recommended to replace the main PCB and control PCB.
Cooling fan warning signal – If the signal is given out, check the cooling fan
cover for clogging. You can also monitor the state of WAF signal in
d022.
4-6-24 Starting Contact Signal
The inverter gives out the starting contact signal (FR) while it is receiving an
operational command. The FR signal is given out, regardless the setting of
the run command source setting (
A002). If the forward operation (FW) and
reverse operation (RV) are given at the same time, the inverter stops the
motor operation.
