Probable Cause: Outside electrical noise is entering the signal, or there is a high-frequency ON/OFF repetition error.

The Siruba L818-M1 (part of the L818 series) is an industrial high-speed single-needle lockstitch machine. While there isn't a specific "2021-only" error list, these machines use a standard set of electronic control error codes found in their technical manuals. Common Error Codes (E / ERR List)
