Fault Name
Overcurrent at constant speed
Cause
Possible Solution
Ground fault or short circuit exists in
the output circuit.
Check whether short-circuit occurs on the motor, motor cable or
contactor.
Control mode is SVC or FVC but
motor auto-tuning is not performed.
Set motor parameters according to motor nameplate and perform
motor auto-tuning.
The overcurrent stall prevention
parameters are set improperly.
Ensure that current limit is enabled (F3-19 = 1).
The setting of current limit level (F3-18) is too large. Adjust it
between 120% and 150%.
The setting of current limit gain (F3-20) is too small. Adjust it
between 20 and 40.
The AC drive power class is small.
If output current exceeds rated motor current or rated output
current of the AC drive during stable running, replace a drive of
larger power class.
The AC drive suffers external
interference.
View historical fault records. If the current value is far from the
overcurrent level, find interference source. If external interference
does not exist, it is the drive board or hall device problem.

Fault Name
Overvoltage during acceleration
Cause
Possible Solution
Input voltage is too high.
Adjust input voltage to normal range.
An external force drives motor during
acceleration.
Cancel the external force or install a braking resistor.
The overvoltage stall prevention
parameters are set improperly.
Ensure that the voltage limit function is enabled (F3-23 = 1).
The setting of voltage limit (F3-22) is too large. Adjust it between
700 V and 770 V.
The setting of frequency gain for voltage limit (F3-24) is too
small. Adjust it between 30 and 50.
Braking unit and braking resistor are
not installed.
Install braking unit and braking resistor.
Acceleration time is too short.
Increase acceleration time.
Operating Panel Display
Fault Name
Overvoltage during deceleration
Cause
Possible Solution
The overvoltage stall prevention
parameters are set improperly.
Ensure that the voltage limit function is enabled (F3-23 = 1).
The setting of voltage limit (F3-22) is too large. Adjust it between
700 V and 770 V.
The setting of frequency gain for voltage limit (F3-24) is too
small. Adjust it between 30 and 50.
An external force drives motor during
deceleration.
Cancel the external force or install braking resistor.
Deceleration time is too short.
Increase deceleration time.
Braking unit and braking resistor are
not installed.
Install braking unit and braking resistor.
