Possible Causes
Solutions
Overcurrent at constant
speed
OC3
1: The output circuit is grounded or short
circuited.
2: Motor auto-tuning is not performed.
3: The voltage is too low.
4:Asudden load is added during operation.
5:The AC drive model is of too small power
class.
1: Eliminate external faults.
2: Perform the motor auto- tuning.
3: Adjust the voltage to normal range.
4: Remove the added load.
5: Select an AC drive of
higher power class.
Overvoltage during
acceleration
OU1
1: The input voltage is too high.
2: An external force drives the motor during
acceleration.
3: The acceleration time is too Short.
4:The braking unit and braking resistor are not
installed.
1: Adjust the voltage to normal range.
2: Cancel the external force or install a
braking resistor.
3: Increase the acceleration lime.
4: Install the braking unit and braking
resistor.
Overvoltage during
deceleration
OU2
1: The input voltage is too high.
2:An external force drives the motor during
deceleration.
3: The deceleration time is too Short.
4:The braking unit and braking resistor ere not
installed.
1: Adjust the voltage to normal range.
2: Cancel the external force or install
the braking resistor.
4: Install the braking unit and braking
resistor.
Overvoltage at
constant speed
OU3
1: The input voltage is too high.
2: An external force drives the motor during
deceleration.
1: Adjust the voltage to normal range.
2: Cancel the external force or install
the braking resistor.
Control power supply fault
POFF
The input voltage is not within the allowable
range.
Adjust the input voltage to the
allowable range.
Lack of voltage
LU
1: Instantaneous power failure occurs on the
input power supply.
2: The AC drive’s Input voltage is not within
the allowable range.
3: The bus voltage Is abnormal.
4:The rectifier bridge and buffer resistor are
abnormal.
5: The drive board is abnormal.
6: The main control board is abnormal.
1: Reset the fault.
2: Adjust the voltage to normal range.
3, 4, 5, 6: Looking for technical support
AC drive overload
OL2
1: The load is too heavy or motor-stalled
occurs on the motor.
2: The AC drive model is of too small power
class.
1: Reduce the load and check the motor
and mechanical condition.
2: Select an AC drive of higher power
class.
Motor overload
OL1
1: P9.01 is set improperly.
2: The load is too heavy or motor-stalled
occurs on the motor.
3: The AC drive model is of too small power
class.
1: Set P9.01 correctly.
2: Reduce the load and check the motor
and mechanical condition.
3: Select an AC drive of higher power
class.
