Goodrive300-LIFT series inverter Fault tracking
-101-
Code
Fault
Possible cause
Solution
ENC1D
Encoder
reserve-rotation
fault
Incorrect encoder signal
direction
Set the function code to
change the direction or
reverse the AB signal wires.
ENC1Z
Encoder Z-pulse
disconnection fault
The Z-pulse signal cable is
not connected.
Check the Z-pulse signal
cable.
ENC1U
U disconnection
There are no U, V, or W
signals or there is
interference.
Check the U, V, and W signal
wiring.
OT
Motor
overtemperature
fault
Motor overtemperature
signal
BAE
Brake fault
Brake signal and control
signal are inconsistent
Feedback terminal signal
is interfered.
Check whether the brake is
in good condition.
Check feedback terminal
signal.
CONE
Contactor fault
Brake feedback and
control signal are
inconsistent.
Feedback terminal signal
is interfered.
Check whether the
contactor is in good
condition.
Check feedback terminal
signal.
nPoS
CD signal
unavailable
The sine-cosine or
absolute-value encoder
position signal is lost.
The encoder is interfered.
Check whether the encoder
is in good condition.
Check whether the inverter
and encoder are grounded.
SAFE
STO card fault
The STO card safety
circuit does not work.
The expansion card type
is incorrect.
Check whether the STO
card is in good condition.
Check whether the
expansion card type is
correct.
STL1
STO card circuit 1
exception
Circuit 1 of the STO card
does not work.
Check whether the STO
card is in good condition.
Check circuit 1 of the STO
card.
STL2
STO card circuit 2
exception
Circuit 2 of the STO card
does not work.
Check whether the STO
card is in good condition.
