code
Fault type
Reason
Solution
Err02
Overcurrent during
acceleration
1. The output circuit of AC Drive is
grounded or short circuited.
2. The acceleration time is too short.
3. The startup operation is
performed on the rotating motor.
4. The AC Drive model is of too
small power.
1. Eliminate external faults.
2. Increase the acceleration time.
3. Select rotational speed tracking restart or
start the motor after it stops.
4. Select the AC Drive of higher power.
Err03
Overcurrent during
deceleration
1. The output circuit of AC Drive is
grounded or short circuited.
2. The deceleration time is too
short.
1. Eliminate external faults.
2. Increase the deceleration time.
Err04
Overcurrent at
constant speed
1. The output circuit of AC Drive is
grounded or short circuited.
2. The AC Drive model is of too
small power.
1. Eliminate external faults.
2. Select the AC Drive of higher power.
Err05
Overvoltage during
acceleration
1. Input voltage abnormal.
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. Turn the input power to the normal range.
2. Cancel the external force.
3. Increase the acceleration time.
4. Installed the braking unit and braking
resistor.
Err06
Overvoltage during
deceleration
1.
Input voltage abnormal.
2.
An external force drives the
motor during deceleration.
3. The deceleration time is too
short.
4. The braking unit and braking
resistor are not installed.
1. Turn the input power to the normal range.
2. Cancel the external force.
3. Increase the deceleration time.
4. Installed the braking unit and braking
resistor.
Err07
Overvoltage at
constant speed
1.
Input voltage abnormal.
2.
An external force drives the
motor during deceleration.
1. Turn the input power to the normal range.
2. Cancel the external force.
Err09
Undervoltage
1. Instantaneous power failure
occurs on the input supply.
2. The input voltage is not within
the normal range.
3. The AC Drive has an
abnormality.
1. Reset the fault.
2. Adjust the input voltage to normal range.
3. Looking for technical service.
Err10
AC Drive overload
1. The load is too heavy or
lockedrotor occurs on motor.
2. The AC Drive model is of too
small power.
1. Reduce the load and check the motor.
2. Select the AC Drive of higher power.
Err11
Motor overload
The parameter setting of F2.03 does
not match the motor
2. The AC Drive model is of too
small power.
1. Set this parameter correctly.
2. Reduce the load and check the motor.
Err14
Module overheating
1. The ambient temperature is too
high.
1. Lower the ambient temperature.
2. Clean the air filter.
