5 Troubleshooting
5
Fault Code 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
The balance
coefcient is
improper.
Check whether the balance coefcient is proper.
The encoder feedback
signal is abnormal.
Check whether the encoder feedback signal
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 perform
motor auto-tuning again.
If this fault is reported when the slip experiment
is carried on, perform the slip experiment by
using the function set in F3-24.
The motor phase
sequence is incorrect.
Replace any two phases of motor UVW cables.
A controller of a small
power class is used.
The current reaches above the rated AC drive
current when the elevator car without load is in
constant speed running.
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.
5A
The balance
coefcient is
improper.
Check whether the balance coefcient is proper.
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 perform
motor auto-tuning again.
If this fault is reported when the slip experiment

The motor phase
sequence is incorrect.
Replace any two phases of motor UVW cables.
A motor of a small
power class is used.
The current reaches above the rated motor
current when the elevator car without load is in
constant speed running.
Err12
Power supply
phase loss
The power input
phases are not
symmetric.
• Check whether any phase of the three-phase
power supply is lost.
• Check whether the three phases of power
supply are balanced.
• Check whether the power voltage is normal,
and adjust the power voltage.
• Set FC-01 bit 14 to 1 to cancel detection of
this fault for 220 V models.
5A
The drive control
board fails.
