shortcut fault 1
circuited with the ground.
There is fault in the current
detection circuit.
The actual motor power sharply
differs from the VFD power.
is normal or not
Change the hall
Change the main control panel
Set motor parameters correctly.
ETH2
Grounding
shortcut fault 2
The output of the VFD is short
circuited with the ground.
There is fault in the current
detection circuit.
The actual motor power sharply
differs from the VFD power.
Check if the connection of the motor
is normal or not
Change the Hall
Change the main control panel
Set motor parameters correctly.
dEu
Speed deviation
fault
The load is too heavy or stalled.
Check the load and ensure it is
normal. Increase the detection time.
Check whether the control
parameters are normal.
STo
Maladjustment
fault
The control parameters of the
synchronous motors not set
properly.
The autotune parameter is not
right.
The VFD is not connected to the
motor.
Check the load and ensure it is
normal.
Check whether the control
parameter is set properly or not.
Increase the maladjustment
detection time.
LL
Electronic
underload fault
The VFD will report the
underload pre-alarm according
to the set value.
Check the load and the underload
pre-alarm threshold.
ENC1
O
Encoder offline
fault
Encoder line sequence error, or
signal wire is connected
improperly
Check encoder wiring
ENC1
D
Encoder reverse
fault
Encoder speed signal is contrary
to running direction of the motor
Reset encoder direction
ENC1Z
Encoder pulse Z
offline
Z signal wire is disconnected
Check Z signal wiring
OT
Motor
over-temperature
fault
Motor overtemperature input
terminal is valid
Temperature detection resistor is
abnormal
Motor runs in overload condition
in long time or it is abnormal
Check the wiring of motor
overtemperature input terminal
(terminal function 57)
Check whether temperature sensor
functions normally
Check and maintain the motor.
