Possible Cause Solution Fault Type
Overcurrent during
acceleration
E02.04
1. A grounding fault or
short circuit exists in
the output circuit of
the AC drive.
2. The control mode is
SVC, and motor auto‑
tuning is not
performed.
3. The acceleration time
is too short.
4. The overcurrent stall
prevention
parameters are set
improperly.
5. The customized
torque boost or V/f
curve is improper.
6. The motor is started
while rotating.
7. The AC drive suffers
external interference.
1. Check the motor and interrupt contactor
and make sure that they are not short‑
circuited.
2. Set the motor parameters according to
the motor nameplate and perform motor
auto‑tuning.
3. Increase the acceleration time (F0‑17).
4. Ensure that overcurrent stall prevention
is enabled (F3‑19 = 1). The overcurret
stall prevention current (F3‑18) is too
high. Adjust it between 120% and 160%.
The overcurret stall prevention gain (F3‑
20) is too low. Adjust it between 20 and
40.
5. Adjust the customized torque boost or V/f
curve.
6. Enable the flying start function or start
the motor after it stops.
7. Check whether the fault current reaches
the overcurret stall prevention current
(F3‑18) by viewing the fault log. If not, the
fault is possibly caused by external
interference. You need to find out the
external interference source and rectify
the fault. If no external interference
source is found, the driver board or Hall
device may be faulty. Contact the
manufacturers to replace them.
