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 cannot run, the computer shows fault code
“E1”, and the buzzer will ring three times.
Possible Reasons: Communication obstructed between
controller and computer, please check the wire and
make sure the wire connects well and the wire without
any damage..
E2
No Speed Wireless Sensor
Network: Can’t receive the
motor speed sensor
feedback above three
seconds.
Stop and go into fault status, computer buzzer 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.
E3
The motor wire is not
connecting well
top and go into fault status, computer buzzer 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
Current overload
Protection , the motor
electrical is overload
Stop and go into fault status, computer buzzer 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.
