Name Possible Causes Solution Level
Err10
Controller
overload
The mechanical resistance is
too large.
◆
Check whether the brake is released, and
whether the brake power supply is normal.
◆
Check whether the guide shoes are too tight.
5A
improper
◆
-
rect.
The encoder feedback signal
is abnormal.
◆
Check whether the encoder feedback sig-
nal and parameter setting are correct, and
whether the initial angle of the encoder for
the PMSM is correct.
Motor auto-tuning is not
performed properly (the
elevator running current is
higher than the normal in this
case).
◆
Check the motor parameter setting and per-
form motor auto-tuning again.
◆
If this fault is reported when the slip experi-
ment is carried on, perform the slip experi-
ment by using the function set in F3-24.
The phase sequence of the
motor is incorrect.
◆
Check whether the UVW phase sequence of
the motor is right.
The AC drive model is of too
low power class.
◆
Check whether the current has exceeded
the rated current of the AC drive during
stable-speed running of the elevator with
empty car.
Err11 Motor overload
The mechanical resistance is
too large.
◆
Check whether the brake is released, and
whether the brake power supply is normal.
◆
Check whether the guide shoes are too tight.

◆
Check whether the UVW phase sequence of

The motor model is of too low
power class.
◆
Check whether the current has exceeded
the rated current of the motor during sta-
ble-speed running of the elevator with emp-
ty car.
Err12
Power supply
phase loss
The power input phases are
not symmetric.
◆
Check whether the three phases of power
supply are lost.
◆
Check whether the three phases of power
supply are balanced.
◆
Check whether the power voltage is normal.
If not, adjust the power supply.
5A
The drive control board fails.
◆
Contact the agent or the manufacturer.
Err13
Power output
phase loss
The output wiring of the main
circuit is loose.
◆
Check whether the motor wiring is secure.
◆
Check whether the RUN contactor on the
output side is normal.
5A
The motor is damaged.
◆
Check whether the motor is internally ab-
normal.
