Siruba L818f-m1 Error List Extra Quality «High-Quality CHOICE»

Before troubleshooting, always turn off the main power and wait 1 minute for the internal capacitors to discharge, unless the procedure requires the machine to be on.

: Overvoltage or Inertia . This may occur if the power voltage is too high or the machine’s deceleration time is too short for its inertia. siruba l818f-m1 error list

Check : Verify the power supply voltage and adjust the deceleration settings if necessary. Before troubleshooting, always turn off the main power

1.0 Applicable to: Siruba L818F-M1 (M1 control box, firmware v2.3 and later) Check : Verify the power supply voltage and

| Error Code | Meaning | Common Causes | Solution | | :--- | :--- | :--- | :--- | | | Over-voltage (Main circuit voltage exceeds 400V DC) | Unstable power grid; Regenerative energy from rapid stop/start; Faulty power regulator. | Turn off machine for 10 minutes. Check input voltage (should be 220V ±10%). Install a line filter or voltage stabilizer. | | E-8 | Under-voltage (Main voltage drops below 180V DC) | Low mains voltage; Loose power cable; Overloaded extension cord. | Measure wall outlet voltage. Ensure no other heavy machinery shares the same circuit. Replace power cable. | | E-9 | Over-current (Motor current spike) | Seized machine head; Thread tangled in hook; Burnt motor driver IC. | Manually turn the handwheel. If stuck, clean hook area. If free, likely a control box issue – replace main board. | | E-10 | Motor locked / Rotor stuck | Mechanical jam inside the arm; Failed Hall sensor on motor. | Remove belt (if external) or disconnect motor coupling. Rotate motor shaft by hand. If tight, replace motor unit. | | E-15 | Heat sink over-temperature | Continuous high-speed sewing >3 hours; Dust buildup on fan; Fan failure. | Stop sewing for 30 min. Clean ventilation slots of control box. Check if cooling fan spins at startup. |
