Fault
Code
Name Possible Causes Solution
Level
Err10
Controller
overload
● This fault is reported
generally when the
controller runs at the
current higher than the
rated value for a long
time. The causes include:
● The mechanical
resistance is too large.
● The balance coefcient is
improper.
● The encoder feedback
signal is abnormal.
● Motor auto-tuning is not
performed properly (the
elevator running current is
higher than the normal in
this case).
1. Eliminate mechanical problems:
● Check whether the brake is released,
and whether the brake power supply is
normal.
● Check whether the balance coefcient is
proper.
● Check whether the guide shoes are too
tight.
2. Check the motor auto-tuning result:
● Check whether the encoder feedback
signal and parameter setting are correct,
and whether the initial angle of the
encoder for the PMSM is correct.
● Check the motor parameter setting and
perform motor auto-tuning again.
3. If this fault is reported when the slip
experiment is carried on, perform the slip
experiment by using the function set in F3-
24.

Err11 Motor overload
● FC-02 is set improperly.
● The mechanical
resistance is too large.
● The balance coefcient is
improper.
● Restore FC-02 to the default value.
● Refer to the solution of Err10.
3A
Err12
Power supply
phase loss
● The power input phases
are not symmetric.
● The drive control board
fails.
● Check whether the three phases of
power supply are balanced and whether
the power voltage is normal. If not, adjust
the power supply.
● Contact us or directly our agent.
4A
Err13
Power output
phase loss
● The output wiring of the
main circuit is loose.
● The motor is damaged.
● Check whether the motor wiring is
secure.
● Check whether the RUN contactor on the
output side is normal.
● Eliminate the motor fault.
4A
Err14
Module
overheat
● The ambient temperature
is too high.
● The fan is damaged.
● The air lter is clogged.
● Lower the ambient temperature.
● Clear the air lter.
● Replace the damaged fan.
● Check whether the installation clearance
of the controller satises the requirement.
