Fault
code
Fault type
Possible cause
Solutions
2. The rated parameter of
the motor does not set
correctly.
3. The offset between the
parameters from
autotune and the
standard parameter is
huge
4. Autotune overtime
parameter according to
the motor name plate
3. Empty the motor load.
4. Check the motor
connection and set the
parameter.
5. Check if the upper limit
frequency is above 2/3 of
the rated frequency.
EEP
EEPROM fault
1. Error of controlling the
write and read of the
parameters
2. Damage to EEPROM
1. Press STOP/RST to
reset
2. Change the main
control panel
PIDE
PID feedback fault
1. PID feedback offline
2. PID feedback source
disappear
1. Check the PID
feedback signal
2. Check the PID
feedback source
bCE
Braking unit fault
1. Braking circuit fault or
damage to the braking
pipes
2. The external braking
resistor is not sufficient
1. Check the braking unit
and , change new braking
pipe
2. Increase the braking
resistor
dEu
Velocity deviation
fault
The load is too heavy or
stalled.
1. Check the load and
ensure it is normal.
Increase the detection
time.
2. Check whether the
control parameters are
normal.
STo
Maladjustment
fault
1. The control parameters
of the synchronous
motors not set properly.
2. The autoturn
parameter is not right.
3. The inverter is not
connected to the motor.
1. Check the load and
ensure it is normal.
2. Check whether the
control parameter is set
properly or not.
3. Increase the
maladjustment detection
time.
END
Time reach of
factory setting
The actual running time
of the inverter is above
the internal setting
running time.
Ask for the supplier and
adjust the setting running
time.
