Fault
Code
Name Possible Causes Solution Level
Err26
Earthquake
signal
101: The earthquake signal
is active and the duration
exceeds 2s.
101: Check that the earthquake
signal is consistent with the
parameter setting (NC, NO) of the
MCB.
3B
Err29
Shorting
PMSM stator
feedback
abnormal
101: The shorting PMSM
stator feedback is
abnormal.
101:
•
Check that the state (NO, NC)
of the feedback contact on the
contactor is correct.
•
Check that the contactor
and corresponding feedback
contact act correctly.
•
Check the coil circuit of
the shorting PMSM stator
contactor.
5A
Err30
Elevator
position
abnormal
101, 102:
In the normal-speed running
or re-leveling running mode,
the running time is larger
than the value of F9-02, but
the leveling signal has no
change.
101, 102:
•
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.
•
Check whether the distance
between two oors is too large,
causing too long re-leveling
running time.
•
Check whether signal loss
exists in the encoder circuits.
4A
Err33
Elevator speed
abnormal
101: The detected running
speed during normal-speed
running exceeds the limit.
102: The speed exceeds
the limit during inspection
or shaft auto-tuning.
103: The speed exceeds
the limit in shorting stator
braking mode.
104: The speed exceeds
the limit during emergency
running.
105: The emergency
running time protection
function is enabled (set
in Bit8 of F6-69), and the
running time exceeds 50s,
causing the timeout fault.
101:
•
Check whether the encoder is
used properly.
•
Check the setting of motor
nameplate parameters.
Perform motor auto-tuning
again.
102: Attempt to decrease the
inspection speed or perform
motor auto-tuning again.
103: Check whether the shorting
PMSM stator function is enabled.
104, 105:
•
Check whether the emergency
power capacity meets the
requirements.
•
Check whether the emergency
running speed is set properly.
