Code
Overvoltage during constant speed
(Inverter display: E.OV2)
5021
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)
5022
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
5030
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)
5034 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)
5040
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
5052
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.
Stall prevention
(Inverter display: E.OLT)
5060
The operating frequency has been dropped to "0"
by the stall preventer function.
