Code
Fault
Description
Possible Cause Solution
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
Phase angle self-study
incorrect
Do phase angle self-study again
Insufficient current when do
phase self-study
Increase current gain of F247 as doing self-study
Error detected on circuit
driver board
Replace driver board
92
Brake detection
failure
No action of output relay Check the relay control circuit
Relay action brake is not
activated
Check whether the brake power cable is loose or
disconnected
Feedback component fail to Regulate feedback component
