Input phase failure
A phase failure occured in the input line of
the main circuit.
The capacitor in the main circuit lacks
capacitance.
Output phase failure
A phase failure occurred in the output line
of the main circuit.
The motor has too big impedance.
Overvoltage during
The input voltage fluctuates abnormally.

(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyristor is connected
to the same power distribution line.
A restart signal is input to the rotating
motor after a momentary stop, etc.
Possible causes
