Fault
code
Fault type
Possible cause
Solution
Keypad data storage error
Re-back up the data on the
keypad.
E-DP
PROFIBUS
communication fault
Communication address is not correct.
The matching resistance is not set well.
The master GSD file is not set up.
The peripheral interference is too large.
Check the related settings;
Check
the
surrounding
environment,
and
eliminate
interference effects
E-NET
Ethernet
communication fault
Ethernet communication fault
The communication mode is set
improperly.
The peripheral interference is too large.
Check the related settings;
Check
the
communication
mode selection;
Check
the
surrounding
environment,
and
eliminate
interference effects
E-CAN
CANopen
communication fault
Line contact is poor.
The matching resistor is not switched
on.
Communication baud rates do not
match.
The peripheral interference is too large
Check the line: switch on the
matching resistor.
Set the same baud rate;
Check
the
surrounding
environment,
and
eliminate
interference effects
ETH1
To-ground
short-circuit fault 1
VFD output is short connected to the
ground
Current detection circuit is faulty
Check whether the motor wiring
is normal
Replace the hall component;
Replace the main control board.
dEu
Speed deviation fault The load is too heavy or stalled.
Check the load to ensure it is
proper,
and
increase
the
detection time;
Check whether the control
parameters are set properly.
STo
Mal-adjustment fault
SM
control
parameters
are
set
incorrectly;
The parameter gained from autotuning
is inaccurate;
The VFD is not connected to the motor.
Check the load and ensure the
load is normal;
Check whether the control
parameters are set correctly;
Increase the maladjustment
detection time.
LL
Electronic underload
fault
The VFD reports underload pre-alarm
according to the setting
Check the load and overload
pre-alarm threshold
ENC1O
Encoder offline fault
In closed-loop vector control the
encoder signal cables is disconnected
Encoder is damaged.
Check the encoder wiring and
re-connect the cables
Check for encoder output
ENC1D Encoder reversal fault
In closed-loop vector control, the
encoder is disconnected or damaged
VFD wiring is improper
Check the encoder wiring and
adjust the wiring
ENC1Z
Encoder Z pulse
offline fault
In closed-loop vector control, the
encoder Z pulse signal cables is
disconnected
Encoder is damaged.
Check the encoder wiring and
re-connect the cables
Check for encoder output
Ot
Motor
overtemperature fault
Long-time overload running or exception
occurred.
The temperature detection resistance is
abnormal
Check the motor, and perform
maintenance on the motor
Check whether the temperature
sensor is proper
