Fatal Fault Signal (MJA)

The following table shows signals that are output when any of trips occurs. It is different form the Output
signal 017 (AL) that will be output for all trips.
This signal converts the trips caused by a hardware failure.
Trips that are evaluated as serious faults are as follows.
Precautions for Correct Use
The inverter hardware may have a fault when this signal is output. Check the error history and
deal with the situation appropriately.
