Err03

 

Overcurrent 

during 

deceleration

1: The output circuit is grounded 
or short circuited.
2: Motor auto-tuning is not 
performed.
3: The deceleration time is too 
short.
4: The input voltage is too low.
5: A sudden

load is added during 

deceleration.
6: The braking unit and braking 
resistor are not installed.
7: Subject to external inter-
ference.

1: Eliminate external faults.
2: Perform the motor autotuning.
3: Increase the deceleration time.
4: Adjust the voltage to the normal range.
5: Remove the added load.
6: Install the braking unit and braking 
resistor.
7: According to the historical fault 
records, if the current value at the time
of fault is far from reaching the over-
current point value, it is necessary to 
find the interference suorce.

Err04

Overcurrent 
at constant 

speed

1: The output circuit is grounded 
or short circuited.
2: Motor auto-tuning is not 
performed.
3: The input voltage is too low.
4: A sudden load is added during 
operation.
5: The AC drive model is of too 
small power class.
6: Subject to external inter-
ference.

1: Eliminate external faults. 
2: Perform the motor autotuning. 
3: Adjust the voltage to the normal range. 
4: Remove the added load. 
5: Select an AC drive of higher power 
class.
6: According to the historical fault 
records, if the current value at the time
of fault is far from reaching the over-
current point value, it is necessary to 
find the interference suorce.

Err05

Overvoltage 

during 

acceleration

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.
5: Subject to external inter-
ference.

1: Adjust the voltage to normal range.
2: Remove the external force or install a 
braking resistor.
3: Increase the acceleration time.
4: Install the braking unit and braking 
resistor.
5: According to the historical fault 
records, if the current value at the time
of fault is far from reaching the over-
current point value, it is necessary to 
find the interference suorce.

Err02

Fault 

name

Overcurrent 

during 

acceleration

Possible causes

1: The output circuit is grounded 
or short circuited.
2: Motor auto-tuning is not 
performed.
3: The acceleration time is too 
short.
4: Manual torque boost or V/F 
curve is not appropriate.
5: The input voltage is too low.
6: The startup operation is 
performed on the rotating motor.
7: A sudden load is added during 
acceleration.
8: The AC drive model is of too 
small power class.
9: Subject to external inter-
ference.

Solutions

1: Eliminate external faults.
2: Perform the motor auto

-

tuning.

3: Increase the acceleration time.
4: Adjust the manual torque boost or V/F 
curve.
5: Adjust the voltage to the normal range.
6: Select rotational speed tracking 
restart or start the motor after it stops.
7: Remove the added load.
8: Select an AC drive of higher power 
class.
9: According to the historical fault 
records, if the current value at the time
of fault is far from reaching the over-
current point value, it is necessary to 
find the interference suorce.
