Goodrive300-LIFT series inverter Fault tracking
-100-
Code
Fault
Possible cause
Solution
Corresponding resistor is
not dialed
The communication is
uneven
resistor
Set the same baud rate
ETH1
Grounding
shortcircuit fault 1
The output of the inverter
is short circuited with the
ground.
There is fault in the
current detection circuit.
Check if the connection of
the motor is normal or not
Change the Hoare
Change the main control
panel
ETH2
Grounding
shortcircuit fault 2
The output of the inverter
is short circuited with the
ground.
There is fault in the
current detection circuit.
Check if the connection of
the motor is normal or not
Change the Hoare
Change the main control
panel
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 inverter 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 inverter will report the
underload pre-alarm
according to the set
value.
Check the load and the
underload pre-alarm point.
ENC1O
Encoder
disconnection fault
Incorrect encoder wiring,
causes the failure to get
the encoder signal.
Incorrect encoder
parameter settings
Check the wiring.
Check encoder parameter
settings.
