Replace

1. EAC drive board

2. Servo encoder

ERR0R_1_2_

Servo motor thermal sensor is activated; speed is reduced to half speed.

1. Inspect motor temperature. If it is not hot, inspect the thermal sensor cable connection.

2. Inspect walk belt tightness. 3. Inspect walk belt wear.

4. Lubricate the belt. If lubrication is not effective, replace the walk belt..

Replace

1. Walk belt

1. Re-start the unit as a test.

2. If issue is repeated, replace the EAC drive board.

Replace

1. EAC drive board

ERR0R_2_2_ 

IGBTover heat malfunction

1. Re-start the unit as a test.

2. If issue is repeated, replace the EAC drive board.

Replace

1. EAC drive board

ERROR_3_1_

Incline motor calibration malfunction

1. Inspect cable connections.

2. After starting the unit, feel the incline motor. If hot, the drive board is malfunctioning.

3. After starting the unit, inspect whether incline 0% switch operates. If so, the drive board is malfunctioning.

 4. Inspect the 0% switch operation.

Replace

1.EAC drive board 2.Incline 0% switch

Power off

Power is off.

1. Re-start the unit as a test.

2. If issue is repeated, replace the EAC drive board.

Replace

1. EAC drive board

ERR0R_4_2_

Low voltage supply

1. Power supply is too low.

2. Measure power supply voltage. If too low, external power supply is insufficient. Please have an electrician address the situation.

3. After fixing the power supply, use the product to confirm its safety.
