Cause and
correction
Assumed cause Correction Prevention
(1) The inverter’s power supply
voltage exceeds the specified
range.
Measure the input voltage.
→ Decrease the power supply
voltage to within the specified
range.
→ If the power supply voltage is
within the specified range, there
is a possibility of an inverter fail-
ure.
Input the correct voltage.
(2) A surge current occurred the
input power supply
.
When the phase advance capac-
itor is turned ON or OFF in the
same power supply system, or
when the thyristor converter op-
erates, the input voltage may
transiently become abnormally
high (i.e., surge).
→ Install a DC reactor.
