Appendix B Para. Fault List Summary
Code
Fault
Description
Possible Cause
Solution
reverse
in operation
Encoder is inconsistent with
the motor phase sequence
Change motor or encoder phase sequence
Motor reversal at start, and
the current reaches the
current limit
Current limit is too low, or the motor does not match
85
Velocity
detected at stop
Brake loose, the elevator car
slides
Check brake
Encoder interfered or loose
Fasten encoder, eliminate interference
86
Motor phase
sequence error
Motor wiring reverse
Anti-line or adjust parameters
87
Overspeed in
the same
direction (withi
n the
maximum allow
ed range)
Galloping in the field-loss
status of synchronous motor
Check motor
Incorrect self study in angle
of synchronous motor
Restart self study
Encoder parameter error
or interfered
Check encoder circuit
Excessive forward load or
load mutation
Check the external causes for load mutations
88
Overspeed in
the reverse
direction (withi
n the
maximum allow
ed range)
Galloping in the field-loss
status of synchronous motor
Check motor
Incorrect self study in angle
of synchronous motor
Restart self study
Encoder parameter error
or interfered
Check encoder circuit
Excessive reverse load or
load mutation
Check the external causes for load mutations
89
Wrong phase
sequence
of UVW
encoder
Problem with
encoder connection or
wrong parameters
Check the connection or change the parameters
90
Encoder comm
unication
failure
Encoder fault
Check encoder wiring and try to do encoder self study
91
Abc over-curre
nt (three-phase
Instantaneous v
alue)
Motor single-phase
ground short circuit
Check motor and the output wire circuit
Encoder fault
Check whether the encoder is damaged or the wiring is
correct
Encoder wrong phase
Check encoder phase
Motor wrong phase
Check encoder phase
