8. Basic Troubleshooting

(1). Error Code and Measurement：

Error Code Cause of The Problem Status and Measurement

ER0. 1

1. Power module detected error.

2. Abnormal over current or voltage occurred..

Motor and machine will be shutting down.

Please check the power module.

Please check the power board over current circuitry.

ER0. 2

E²PROM (IC3) r/w malfunction.

Motor and machine will be shutting down.

Replace the IC3 memory unit.

ER0. 4

1. When power on, detected high voltage

2. Connect the wrong voltage or supply power is too high.

3. Aluminum casing resistor for the brake circuit is defective or power

board F1 fuse burst.

Motor and machine will be shutting down.

Please check the AC power. (Too high)

＊If control box is AC 220V system, don’t use the AC 380V power voltage,

otherwise the LCD will display ER0. 4 after 2 second of power ON. If continue

supply the 380V power, the electrolytic capacitors (C4,C5) of power board will

burst open over a period of time and cause the fuses (F1,F2) of EMI board open

circuit.

Please check the power board.

Please check the aluminum casing resistor and power board F1 fuse.

ER0. 5

1. When power on, detected low voltage

2. Connect the wrong voltage or supply power is too low.

Motor and machine will be shutting down.

Please check the AC power. (Too low)

Please check the power board.

ER0. 7

1. Bad connection at the motor connector.

2. Synchronizer (sensor) signal error.

3. Machine locked or object stuck in the motor pulley.

4. Sewing material is too thick.

Motor and machine will be shutting down.

Please check the motor or motor connection.

Please check the synchronizer (sensor) and its signal.

Please check the machine head to see if objects stuck in the motor pulley, or rotate not smoothly.

ER0. 8

Operation box linked to CPU interface had communication error

Motor and machine will be shutting down.

Please check the operation box.
