 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
