Code
Overcurrent during acceleration
(Inverter display: E.OC1)
6910
During acceleration, the output current of the
inverter became double the rated current
Overcurrent during constant speed
(Inverter display: E.OC2)
6911
During constant-speed operation, the output
current of the inverter became double the rated
current.
Overcurrent during deceleration
(Inverter display: E.OC3)
6912
During deceleration, the output current of the
inverter became double the rated current.
Overvoltage during acceleration
(Inverter display: E.OV1)
6920
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)
6921
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)
6922
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
6930
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)
6934
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.
