9. 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.
3. Resistor for the LV is damaged or F2 fuse open.
Motor will be shut down.
Please check the power module.
Please check the main board over current circuitry.
Please check the resistor (220Ω 30W) for the limited voltage or F2 fuse.
ER0. 2
E²PROM (IC7) r/w malfunction.
Motor will be shut down.
Replace the IC7 memory unit.
ER0. 4
1. When power on, current sensor detected high voltage.
2. Connect the wrong voltage, too high.
3. Parameter【130. OVD】setting is wrong, too low.
Motor will be shut down.
Please check the AC power. (Too high.)
Please check the parameter【130.OVD】setting value of the main board. (Use factory default setting)
Note : 1. Don’t adjust this parameter unless is really necessary. Wrong setting may cause problem.
2. If set wrong and【ER0. 4】shown. The only solution is to reset.
＊ When reset, please check the machine code that need to match the machine head
currently used.
ER0. 5
1. When power on, current sensor detected low voltage.
2. Connect the wrong voltage, too low.
3. Parameter【131. LVD】setting is wrong, too low.
Motor will be shut down.
Please check the AC power. (Too low.)
Please check the parameter【131. LVD】setting value of the main board. (Use factory default setting)
ER0. 7
1. Bad connection at the motor connector.
2. Synchronizer (sensor) signal error.
3. Synchronizer is single position type, and parameter set wrong type.
4. Machine locked or object stuck in the motor pulley.
5. Sewing material is too thick.
6. Circuitry of power module is faulty.
Motor will be shut down.
Please check the motor or motor connectors’ connection.
Please check the Synchronizer (sensor) and its signal.
Please check the parameter【177. SIN】setting. (set「OFF」for 2 position type synchronizer.)
Please check machine head to see if objects stuck in the motor pulley, or rotate not smoothly.
Please check the circuitry of power module.
ER0. 8
Operation box linked to CPU interface had communication error.
Motor will be shut down.
Please check the Operation Box and its connection.
