Indication
Details and causes of abnormality
Remedies
OU2
•
Internal DC overvoltage at constant
speed
Remove sharp variations at load side
(parameters P002, P062, P064 and
P066).
OU1
•
Internal DC overvoltage during
deceleration
•
Extend deceleration time.
LU
•
Power supply voltage below 85% of its
rating
•
Measure power supply voltage and
check input for open phase.
•
Check ride-through restart function.
OL
•
The output current exceeds 125% of
electronic thermal setting current or
140% of rated current of inverter for more
than 1 minute.
•
Check electronic thermal setting
current.
•
Check and adjust torque boost level
(parameter P007).
•
Reduce load.
OH
•
Heat sink overheating
•
Check ambient temperature.
AU
•
External fault stop input signal is input
from control circuit terminals.
•
Check if the external signal is proper
and if timing circuit is correct.
OP
•
The power is turned ON with run signal
ON.
•
Timeout detected
•
The communication cable comes off.
•
The operation panel comes off.
•
Check start mode (parameter P057).
•
Check communication setting and
wiring.
•
Reduce the interference around the
inverter.
•
Check the connection between
operation panel and the inverter.
FAN
•
Cooling fan abnormality
•
Check if the cooling fan is locked.
SEr
•
Speed search failed
•
Incorrect motor rotation direction
•
The rating of the motor is too small
compared with that of inverter.
•
Motor rotates slowly during normal
operation.
•
Reduce the noise around the
inverter.
•
Check the rotation direction of motor.
CPU
•
Too much interference is applied to the
inverter
•
Reduce the interference around the
inverter.
Er1*
2
•
Communication between the inverter
unit and the operation panel failed
•
Check if the operation panel is
connected properly to the unit.
Er2
•
VF200 unit firmware version>Operation
panel firmware version
•
Check the firmware version.
