Siruba L818fm1 Error List Work !!exclusive!! Site

| Code | Meaning | Possible Causes & Solutions | | :--- | :--- | :--- | | | Shaft blocked, connection or positioning problem | Primary Cause : Common error indicating a blocked shaft, poor connections, or positioning issues. Solutions : 1) Turn off the power for 30 seconds and restart. 2) Check if the hook is jammed or the belt is slipping. 3) Ensure the motor encoder signals are consistent with the positioning sensor. | | E-001 | IPM over-current / over-voltage | Caused by an overload or short circuit in the motor drive module. Solutions : Turn off the machine and check for a mechanically stuck sewing machine head or a short in the motor windings. | | E-003 | Auxiliary equipment undervoltage (24V) | Indicates a problem with the low-voltage power supply. Solutions : Check the auxiliary power supply module and its connections to the main control board. | | E-004 | EEPROM fault | A memory chip on the control board has corrupted data. Solutions : May require reprogramming or replacement of the control board by a professional. | | E-005 | Motor running abnormality | Primary Cause : Suggests the main motor is not responding correctly to commands. Solutions : Check motor wiring and the encoder for any faults. | | E-007 | Motor locked-rotor error | Primary Cause : The motor has tried to turn but cannot move. Solutions : Turn off the machine and manually rotate the handwheel to check for a mechanical jam. | | ERR-00 / ERR-01 | Input signal self-check error | Primary Cause : The control system detects a fault during its initial power-on check. Solutions : Return the foot pedal to its neutral position and check the pedal's signal cable connection. | | Error 11 | Pause switch pressed | A non-critical alert; the machine is waiting for user input. Solutions : Press the RESET key to clear the error. Move the presser foot if necessary to continue sewing. | | Error 121 | Thread trimming cannot be completed | Indicates a failure in the automated thread cutting sequence. Solutions : Turn off the machine and inspect the fixed and movable knife edges for damage or wear. |

The appearing on your control box panel

If you have cleared all physical blockages and verified your voltage, but an error code like E03, E07, or E14 persists, the internal circuit boards may require expert servicing from an authorized dealer representing . To help drill down to the exact solution, let me know:

This guide provides a comprehensive breakdown of the error codes, their causes, and troubleshooting steps for the sewing machine. siruba l818fm1 error list work

These codes are frequently associated with the HVP series control boxes used in the L818 series.

Wipe or blow lint away from the motor cooling fins and control box vents every shift to avoid heat buildup.

: Communication between the servo motor internal encoder and the CPU has dropped completely. Step-by-Step Fix : Unplug the system power cord. Inspect the main multi-pin motor encoder wire connector. | Code | Meaning | Possible Causes &

: With the power switch on, hold down the P key on the digital panel until the screen changes to display parameter groups (e.g., 01.P ).

Ensure the upper thread is passing smoothly through all standard tension discs and guides without catching on burrs.

Below is a comprehensive breakdown of the error codes, common mechanical issues, and the troubleshooting steps required to get your machine working again. 🛠️ Electronic Error Code List 3) Ensure the motor encoder signals are consistent

Ensure the clearance between the needle and the rotary hook tip is tight—ideally around 0.05mm . If it is too wide, the hook will miss the loop, causing skipped stitches. 3. Loose or Malformed Stitching (Bird-Nesting)

Siruba L818F-M1 industrial sewing machine, error codes typically appear on the control box display to signal electrical or mechanical issues. The most common errors related to the drive system include voltage irregularities, motor locks, and signal failures between the encoder and control unit. Common Error Codes & Troubleshooting Error Code Probable Cause Voltage or Load Issue: Supply voltage is too low or machine torque is too high.
