Fault Code
Fault Description
Fault Processing
E1
Communication abnormal: The
control and computer has
abnormal communication after
start
The controller is not working and going into fault. The machine can
not run, the computer shows fault code “E1”, and the buzzle will
ring three times.
Possible Reasons: Communication obstructed between controller
and computer, please check the wire and make sure the wire
connect well and the wire without any damager..
E2
No Speed Wireless Sensor
Network: Can’t receive the
motor speed sensor feedback
above three seconds.
Stop and go into fault status, computer buzzle will ring 3 tones and
shows fault code“E2”. Other areas show blank. After 10 seconds
will go into ready mode, and can restart.
Possible Reasons
：
Can’t receive the motor speed sensor
feedback above three seconds, please check sensor plug and
motor connect wire and the controller.
The motor wire is not
connecting well
Stop and go into fault status, computer buzzle will ring 3 tones
and shows fault code“E3”. Other areas show blank. After 10
seconds will go into ready mode, and can restart.
Possible Reasons
：
Check if the motor wire is connected well and
re-connect the motor wire well if not; check if the controller has the
smell and change the controller if have
E3
Current overload Protection ,
the motor electrical is overload
Stop and go into fault status, computer buzzle will ring 3 tones
and shows fault code“E3”. Other areas show blank. After 10
seconds will go into ready mode, and can restart.
Possible Reasons
：
Over the rated load cause too much electricity
that make system Self-preservation or some parts blocked and
make DC motor can’t process. Adjust the machine and restart.
Another please check the DC motor or controller have any burned
smell or not. If yes, please change the motor or controller. Another
make sure the power and voltage is comply with standard.
E4
Incline self-learning fault
Check incline motor sense wire and AC wire are inserted well; AC
wire is right inserted according to the indentify in the incline
motor; make sure the incline motor wire without damager; after
check those, press the button on controller, then start self-learning
again.
E5
Incline sensor error
Check incline motor sense wire and AC wire are inserted well; AC
wire is right inserted according to the indentify in the incline
motor; make sure the incline motor wire without damager; after
check those, press the button on controller, then start self-learning
again.
E6
Explosion-Proof Protection
：
Some unusual condition of
power or voltage that cause
damage to the motor drive
circuit.
Stop and go into fault status, computer buzzle will ring 3 tones
and shows fault code“E6”. Other areas show blank. If recover then
go into ready mode, then can restart.
Possible Reasons
：
The power voltage is less than normal or the
controller has some problems. Make sure the motor wire is
connecting well.
E7
The upper EEPROM is
recorded faulty
Change upper EEPROM
E8
The lower EEPROM is
recorded faulty
Change lower EEPROM
