Fault Code Name Possible Causes Solution Level
Err30
Elevator position
abnormal
Subcodes 101, 102:
In the normal-speed
running or re-leveling
running mode, the
leveling signal has
no change within a
certain time period.
ā¢ Check whether the leveling signal cables are
connected reliably and whether the signal
copper wires may touch the ground or be
short circuited with other signal cables.
ā¢ Check whether the distance between two
īoors is too large or the re-leveling time set
in F3-21 is too short, causing over long re-
leveling running time.
4A
Err31
DPRAM
abnormal
(NICE3000)
DPRAM read/writing
is abnormal.
Contact us or our agent directly to replace the
MCB.
-
Err32
CPU abnormal
(NICE3000)
The CPU is abnormal.
ā¢ Check jumpers J9 and J10 on the MCB to
see whether only two pins on the right in J9
are shorted.
ā¢ Contact us or our agent directly to replace
the MCB.

Err33
Elevator speed
abnormal
Subcode 101: The
detected running
speed during normal-
speed running
exceeds the limit.
ā¢ Check whether the parameter setting and
wiring of the encoder are correct.
ā¢ Check the setting of motor nameplate
parameters. Perform motor auto-tuning
again.
5A
Subcode 102: The
speed exceeds the
limit during inspection
or shaft auto-tuning.
Decrease the inspection speed or perform
motor auto-tuning again.
Subcode 103: The
speed exceeds the
limit in shorting stator
braking mode.
ā¢ Check whether the shorting PMSM stator
function is enabled.
ā¢ Check whether the motor phase sequence is
correct.
Subcodes 104, 105:
The speed exceeds
the limit during
emergency running.
ā¢ Check whether the emergency power
capacity meets the requirements.
ā¢ Check whether the emergency running
speed is set properly.
Subcode 106: The
speed deviation
detected by the MCB
is too large.
ā¢ Check wiring of the encoder.
ā¢ Check whether SPI communication between
the MCB and drive board is normal.
Err34
Logic fault
Logic of the MCB is
abnormal.
Contact us or our agent directly to replace the
MCB.
