Chapter 8 Troubleshooting
EV3200 can detect 19 types of faults. When fault occurs, you can get the information of fault codes, DC bus voltage, output
current, operating frequency and terminal status by reviewing the values of F9.02 ~ F9.09. You can check the faults according
to the following table and note down the fault phenomena before seeking technical service.
Fault code
Fault type
Possible cause
Action to take
E001
Over-current in Acc
process
1) Acc time is too short.
2) Restart the motor in motion when momentary
stop occurs.
3) Incorrect external wiring
4) Incorrect wiring of PG
5) Output phase failure
1) Prolong the Acc time;
2) Start the motor after it stops.
3) Wiring correctly
4) Change the setting of F4.02 or the wiring of PG
5) Check the cable connection of the motor
E002
Overcurrent in Dec
process
1) Dec time is too short
2) Output phase failure
1) Increase Dec time or adjust PI parameters
2) Check the cable connection of the motor
E003
Overcurrent in
constant speed
operation
1) Sudden change of load
2) Abnormal load\
3) Output phase failure
1) Adjust PI parameters
2) Check load
3) Check the cable connection of the motor
E004
Overvoltage in Acc
process
1) Abnormal input voltage
2) Unsuitable setting of PI parameters
3) Big load inertia
1) Check input power source.
2) Adjust PI parameters
3) Connect external braking resistor
E005
Overvoltage in Dec
process
1) Dec time is short
2) Unsuitable selection of braking resistor
3) Abnormal input voltage
4) Unsuitable setting of PI parameters
1) Prolong Dec time
2) Re-select the braking resistor
3) Check input voltage
4) Adjust PI parameters
E006
Overvoltage in
constant speed
operation
1) Abnormal change of input voltage
2) Energy regenerated by negative torque load
1) Mount input reactor
2) Connect external braking resistor

E009
Output phase loss
The output cables of the inverter are broken,
phase failure or 3-phase loads are severely
unbalanced
Check the 3-phase output cables of the inverter and
check if the 3-phase loads are balanced

E013 Inverter
overload
1) Heavy load
2) Low mains voltage
3) PG error
1) Select inverters with bigger ratings
2) Check mains voltage
3) Check the PG wiring or replace the PG
E014 Motor
protection
1) Motor rated current setting error
2) Motor’s max allowable operating current set
too small
3) Motor model selection error
1) Check the setting of F6.03
