Possible Causes
F536
:
E536 is generated 4 times.
E536
:
Detect offset error of current sensor at
starting
Inverter board failure
(Current sensor)
F538
:
Power module failure
Inverter board failure (IGBT)
IGBT
:
Insulated gate Bipolar Transistor
F53C
:
E53C is generated 4 times.
E53C
:
Charging error of main circuit capacitor at
starting
Inverter board failure
(
Capacitor short-circuited
)
Trouble
Shooting
Replacing of inverter board

Causes
Condition of command frequency
<
actual ferequency remains temporarily
(
5 seconds
)
①
Lightning surge sometimes shifts the detected rotating speed significantly, leading to
abnormal stop of the unit due to over current.
②
Inverter board failure (Frequency detection part)
Trouble
Shooting
①
Regardless alarm is generated, restart after 3 minutes standby (Permanent retry
)
Operation continues if the external factor like lightening is improved.
②
If there is no external factor, it seems to be inverter board failure. Replace inverter board.
