| Error Code | Meaning | Likely Cause & Solution | | :--- | :--- | :--- | | | Machine head locked / overload | Thread tangled in hook, foreign object in rotary hook, or mechanical seizure. Turn off power, clean hook area, and check for free rotation. | | E-02 | Motor position signal error | Faulty synchronizer or encoder. Check the position sensor near the handwheel. | | E-03 | Overvoltage (power supply) | AC input voltage too high. Use a voltage regulator. | | E-04 | Undervoltage | AC input voltage too low. Check power source and cables. | | E-05 | Overcurrent | Motor short circuit or driver board failure. Stop immediately; service required. | | E-06 | Motor overspeed | Control board failure. Turn off machine, restart. If persists, replace control box. | | E-07 | EEPROM (memory) error | Settings corrupted. Reset to factory defaults via panel (see manual). | | E-08 | Communication error (panel to control box) | Loose flat cable between panel and main box. Reconnect securely. | | E-09 | Needle up/down position not found | Magnet on handwheel missing or sensor faulty. | | E-10 | Presser foot lift motor error (if equipped) | Foot lift solenoid stuck or jammed. | | E-11 | Thread trimmer solenoid error | Trimmer stuck or solenoid coil open circuit. | | E-12 | Winding stop sensor error | Bobbin winder mechanism faulty or sensor disconnected. |
The control system cannot detect the main motor type or speed. Check motor connectors. Emergency Switch Active
: Always disconnect the power before opening electronic control boxes or performing internal repairs to avoid electrical shock.
