Fault
code
Fault type
Possible cause
Corrective measure
exception
upward and downward
commands at the same time.
POE
Terminal command
exception at
power-on
The terminal command is
detected at power-on.
Check whether P01.18 is set to
enable the VFD reports a fault
when a terminal command is
valid at power-on.
Check the input terminal signal.
SLE
Loose rope
protection fault
The hook rope is abnormal.
The downward loose rope
parameter setting is
improper.
Check whether the hook rope is
normal.
Check whether the downward
loose rope detection torque is
proper.
bE
Brake failure
The
brake
force
is
insufficient.
The brake detection
parameter setting is
improper.
Check whether the brake is
normal.
Check whether the brake slip
parameter setting is proper.
ELS
Master/salve
position
synchronization fault
The encoder pulse
difference between the
master and slave is too
great.
The pulse threshold setting
is improper.
Check the encoders for the
master and slave.
Check whether the pulse
threshold of the slave is too
small.
AdE
Analog speed
reference deviation
fault
If the speed is given by
analog, the analog voltage is
greater than 1.0V after
zero-position detection is
complete.
Check the analog wiring and
current voltage value.
OtE1
PT100
overtemperature
fault
The current environment
temperature is too high.
PT100 detection circuit is
abnormal.
PT100 overtemperature
protection setting is
improper.
Check the current environment
temperature.
Check PT100 circuit.
Check whether PT100
overtemperature protection
point is too small.
OtE2
PT1000
overtemperature
The current environment
temperature is too high.
Check the current environment
temperature.
