The sewing machine inertia is too high. The motor might be trying to stop faster than the machine’s mechanics allow.
: Remove the needle plate and blow out all packed fibers accumulating around the feed dog teeth and bobbin case area.
If you’ve used industrial overlockers, you know Siruba as the “Toyota of sewing machines” – reliable, boring, but workhorses. Then came the , a fully electronic 4-thread overlocker with a servo motor, automatic thread trimmer, and… a surprisingly expressive error system. Yes, this machine complains . But cleverly.
This comprehensive guide breaks down the core digital and mechanical errors you might encounter while working with this machine, what they mean, and how to resolve them quickly to get your assembly line back to work. Core Electronic & Motor Error Codes
Check the motor connector pins and wiring. Ensure no "extraordinary" or noise-heavy signals are interfering with the input. Needle Position Error siruba l818fm1 error list work
Turn off power. Test outlet line voltage with a multimeter. Increase the parameter deceleration time if inertia triggers it. / E20 Undervoltage Protection
is a high-speed, direct-drive lockstitch sewing machine popular for its efficiency and reliability. However, like any advanced computerized industrial sewing machine, it can display error codes. These codes are crucial for maintaining workflow and avoiding damage to the motor or mechanical components. Understanding the Siruba L818FM1 Go to product viewer dialog for this item.
A3: The complete error list is found in the official service manual for your specific L818F-M1 model . The error codes can vary depending on the type of control box installed on your machine (e.g., a "lower-mounted" vs. "panel-mounted" control box). These details are model-specific and require the original documentation.
An extraordinary signal has been inputted into the control system, or the motor connector is not properly plugged in. The sewing machine inertia is too high
The position detector (synchronizer) signals are broken, or the connector is loose. The machine does not know where the needle is.
: Heavy industrial lockstitch motors draw significant current during startup. Plug the machine directly into a dedicated wall outlet rated for the control box's voltage specifications.
If you tell me the on your panel, I can provide a specific step-by-step fix . If you're experiencing a mechanical problem (like broken thread or skipping stitches), please let me know: The type of fabric you are sewing The needle size How often the issue occurs
: Try lengthening the deceleration time in the settings. If the motor is locked, check for mechanical obstructions. E3: Encoder/Positioning Signal Error If you’ve used industrial overlockers, you know Siruba
The is a high-speed, single-needle industrial lockstitch sewing machine designed for light to medium-weight fabrics. While the mechanical base is robust, errors typically arise from its electronic control system (often a Powermax or similar direct-drive controller).
Always use an industrial voltage stabilizer if your factory floor experiences frequent power surges or drops. This stops premature E19 and E20 over/undervoltage warnings.
By following this , you can quickly diagnose issues and ensure your machine stays in working order.
Rethread the entire machine, ensuring the thread passes through all tension discs correctly. :
The main motor has exceeded its safe operating temperature. | 1. Allow the machine to cool down for at least 15-20 minutes. 2. If this occurs frequently, check if the machine is being overloaded (e.g., sewing very heavy material for long periods). | | | Communication Error (for certain control boxes)
: Usually a result of excessive tension, poor-quality thread, or a burred needle.
