Fault
categories
Possible reasons for fault
Actions
E013
Drive
overload
Parameters of motor are wrong
Auto-tune the parameters of
motor
Too heavy load
Select the drive with bigger
power
DC injection braking current is
too big
Reduce the DC injection braking
current and prolong the braking
time
Too short acceleration time
Prolong acceleration time
Low AC supply voltage
Check the AC supply voltage
Improper V/F curve
Adjust V/F curve or torque boost
value
E014
Motor
over-load
Improper motor’s overload
protection threshold
Modify the motor’s overload
protection threshold.
Motor is locked or load
suddenly become too big
Check the load
Common motor has operated
with heavy load at low speed
for a long time.
Use a special motor if the motor
is required to operate for a long
time.
Low AC supply voltage
Check the AC supply voltage
Improper V/F curve
Set V/F curve and torque boost
value correctly
E015
external
equipment
fails
Terminal used for stopping the
drive in emergent status is
closed
Disconnect the terminal if the
external fault is cleared
E016
EEPROM
R/W fault
R/W fault of control
parameters
Press STOP/RST to reset, seek
service
E017
Communicatio
n timeout
The setting time is too shot
Set b3.02 to 0, it means do not
detection
E018
Contactor not
closed
Low AC supply voltage
Check the AC supply voltage
Contactor damaged
Replace the contactor in main
circuit and seek service
Soft start resistor is damaged
Replace the soft start resistor and
seek service
Control circuit is damaged
Seek service
Input phase loss
Check the wiring of R, S, T.
E019
Current
detection
circuit
fails
Wires or connectors of control
board are loose
Check and re-wire
Auxiliary power supply is
damaged
Seek service
Hall sensor is damaged
Seek service
Amplifying circuit is abnormal
Seek service
E020
System
interference
Terrible interference
Press
STOP/RST
key to reset or
add a power filter in front of
power supply input
DSP in control board
read/write by mistake
Press
STOP/RST
key or seek
service.
E023
Parameter
copy
error
Panel’s parameters are not
complete or the version of the
parameters are not the same as
that of the main control board
Update the panel’s parameters
and version again. First set b4.04
to 1 to upload the parameters and
then set b4.04 to 2 or 3 to
download the parameters.
Panel’s EEPROM is damaged
Seek service
E024
Auto-tuning
fault
Improper settings of
parameters on the nameplate
Set the parameters correctly
according to the nameplate
Prohibiting contra
Auto-turning during rollback
Cancel prohibiting rollback
Overtime of auto-tuning
Check the motor’s wiring
Check the set value of
A0.10(upper limiting frequency),
make sure if it is lower than the
rated frequency or not
E026
The load of
drive is lost
The load is lost or reduced
Check the situation of the load
E027
