Code
Overvoltage during acceleration
(Inverter display: E.OV1)
5220
During acceleration, regenerative energy has
caused the main circuit DC voltage in the inverter
to exceed the specified value.
Overvoltage during constant speed
(Inverter display: E.OV2)
5221
During constant-speed operation, regenerative
energy has caused the main circuit DC voltage in
the inverter to exceed the specified value.
Overvoltage during deceleration
(Inverter display: E.OV3)
5222
During deceleration, regenerative energy has
caused the main circuit DC voltage in the inverter
to exceed the specified value.
Inverter overload shut-off
(Inverter display: E.THT)
The output current of the inverter has been more
5230
than 150% of the rated current. Because the
output current is less than 200%, overcurrent
cutoff has not occurred. Output has been stopped
to protect the output transistor.
Motor overload shut-off
(Inverter display: E.THM)
5234
The electronic thermal alarm built into the
inverter has detected an overload of the motor of
overheating in the motor due to poor cooling, and
has stopped the output from the inverter.
Fin overheat
(Inverter display: E.FIN)
5240
The cooling fins on the inverter have overheated,
so the temperature sensor has stopped the
output from the inverter.
Input phase failure
(Inverter display: E.ILF)
A phase failure has occurred in one of the three
5252
input phases (R, S and T) to the inverter, or there
was a big difference in voltage between the input
phases. This has stopped the output from the
inverter.
