Troubleshooting
Caution
Be sure to turn off power switch before connect or disconnect connector, or parts damage may be
occurred.
Turn the main power supply
off, and then disconnect the
connection between the
compressor and inverter.
Is the
secondary
current of the inverter
higher than
∗
A (see below)
for each
phase?
Is the
inverter
output voltage
generated
approximately at the same
increasing speed on each
phase after turning
on again? (
∗
)
(U-V, V-W,
W-U)
Continuity check in the
power transistor (IGBT)
Is the continuity
normal?
YES
NO
NO
YES
NO
* When operating compressor
with compressor output line
disconnected, the compressor
stops due to malfunction after
elapsed time of 5 seconds.
Therefore, check the voltage
increase for 5 seconds.
