Fault Name

Possible Cause Solution
Fault Type
Overcurrent during
deceleration
E03.04
1 A grounding fault or
short circuit exists in the
output circuit of the AC
drive.
2 The SVC control mode
is adopted, and motor
auto-tuning is not
performed.
3 The set deceleration
time is too short.
4 The overcurrent stall
suppression setting is
improper.
5 The power supply unit
is not provided with a
braking unit and no
braking resistor is
installed.
6 The AC drive suffers
external interference.
1 Check the motor and make sure that the
motor is not short-circuited or open-circuited.
2 Set the motor parameters according to the
motor nameplate and perform motor auto-
tuning.
3 Increase the deceleration time (F0-18).
4 Ensure that overcurrent stall suppression
(F3-19) is enabled.The overcurrent stall action
current (F3-18) is too high. Adjust it to a value
between 120% and 150%.The overcurrent stall
suppression gain (F3-20) is too low. Adjust it
to a value between 20 and 40.
5 Replace the power supply unit with one that
has a braking unit and install a braking
resistor.
6 Check whether the fault current reaches the
overcurrent stall suppression current (F3-18)
by viewing the fault log. If not, the fault is
possibly caused by external interference. In
this case, find out the external interference
source and rectify the fault.If no external
interference source is found, the drive board
or Hall device may be faulty. In this case,
contact the manufacturer for replacement.

Overcurrent at
constant speed
E04.04
1 A grounding fault or
short circuit exists in the
output circuit of the AC
drive.
2 The SVC control mode
is adopted, and motor
auto-tuning is not
performed.
3 The overcurrent stall
suppression setting is
improper.
4 The AC drive power
rating is too low.
5 The AC drive suffers
external interference.
1 Check the motor and make sure that the
motor is not short-circuited or open-circuited.
2 Set the motor parameters according to the
motor nameplate and perform motor auto-
tuning.
3 Ensure that overcurrent stall suppression
(F3-19) is enabled.The overcurrent stall action
current (F3-18) is too high. Adjust it to a value
between 120% and 150%.The overcurrent stall
suppression gain (F3-20) is too low. Adjust it
to a value between 20 and 40.
4 During stable running, if the running current
exceeds the rated motor current or rated
output current of the AC drive, replace the AC
drive with one of higher power rating.
5 Check whether the fault current reaches the
overcurrent stall suppression current (F3-18)
by viewing the fault log. If not, the fault is
possibly caused by external interference. In
this case, find out the external interference
source and rectify the fault.If no external
interference source is found, the drive board
or Hall device may be faulty. In this case,
contact the manufacturer for replacement.
