Siruba L818fm1 Error List Work (2025)

The motor senses an excessively high current draw, meaning it is trying to turn but facing intense resistance.

This is the most common operational error code on the production line.

Drops in main power supply lines or loose power connection lines.

When an error occurs, the code will flicker on the control switch panel display. Error Code Probable Cause Recommended Action Abnormal over-current or over-voltage. siruba l818fm1 error list work

Inspect the connector to the motor encoder to make sure it is securely inserted.

Loosen the switch bracket, realign it so the pin is depressed when the machine is flat, and re-tighten the assembly.

The machine has lost track of the needle's "Up/Down" position. Check the detector cable. The motor senses an excessively high current draw,

Check shielding ground wires. Isolate the power cord from heavy-amperage equipment like cutting tables to remove noise. Encoder / Position Sensing Fault

: Ensure the automatic oil pump fills the oil window during high-speed operation, and keep the reservoir filled with clean oil.

: Ensure the power distribution box features a true neutral line. Floating neutrals can damage internal inverter components, leading to unresolvable overvoltage errors. Entering Parameter Calibration Mode When an error occurs, the code will flicker

Check if the machine is jammed or the material is too thick. Ensure the motor is not overloaded. Over Voltage / Inertia

If you'd like to dive deeper into a specific issue, let me know: What is flashing on your screen?

The means the system cannot find its needle-up or needle-down parking positions, which blocks automatic thread trimming.

Pattern cannot be called; reset power or check internal memory. Over-voltage / Encoder Error Check power voltage or motor encoder connector. E3 / ERR3 Motor Locked / Needle Pos Check for machine/motor lock or needle bar position error. E4 / ERR4 Signal / Feed Error Check motor connector signals or feed limit sensor. E8 / ERR8 Detector/ROM Error Check detector UP/DOWN signals or ROM integrity. E10 Counter Zero / Power
