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.
