Fault
Code
Name Possible Causes Solution Level
Err20
Speed
feedback
incorrect
1: AB signals are lost during
auto-tuning.
3: The phase sequence of
the motor is incorrect.
4: Z signal cannot be
detected during auto-tuning.
5: The CD signal cables
of the SIN/COS encoder
break.
7: The UVW cables of the
UVW encoder break.
8: The angle deviation is
too large.
9: Overspeed occurs or the
speed deviation is too large.
10/11: AB signals or CD
signals of the SIN/COS
encoder are interfered with.
12: The detected speed is 0
at torque limit.
13: AB signals are lost
during running.
14: Z signal is lost during
running.
19: The AB analog signal
cables break during low-
speed running.
55: CD signal error or
serious Z signal interference
occurs during auto-tuning.
3: Exchange any two phases of
the motor UVW cables.
1, 4, 5, 7, 8, 10, 11, 13, 14, 19:
Check that all signal cable wiring
of the encoder is correct and
secure.
9: Check that the setting of F1-
00, F1-12, and F1-25 for the
synchronous motor is correct.
12: Check that there is no
mechanical stuck and that the
brake has been released during
running.
55: Check that the grounding is
reliable and eliminate interference
problems.

Err22
Leveling signal
abnormal
101: The leveling signal
is active during oor
switchover.
102: The falling edge of
the leveling signal is not
detected during elevator
startup and oor switchover.
103: The leveling position
deviation is too large in
elevator auto-running state.
101, 102:
•
Check whether the leveling
and door zone sensors work
properly.
•
Check the installation verticality
and depth of the leveling
plates.
•
Check the leveling signal input
points of the MCB.
103: Check whether the steel
rope slips.
1A
Err25
Storage data
abnormal
101, 102:
The storage data of the
MCB is abnormal.
101, 102: Contact the agent or
Monarch.
