[Servo board XX] Communication error with the power regeneration control board (No. XX). (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible *.

Description: A cyclic redundancy check (CRC) or framing abnormality was detected in communication with the power regeneration control board.

CRC abnormality: After a cyclic redundancy check code is added to the communication data, an abnormality is detected during calculation using the generator polynomial. Framing abnormality: No stop bit is detected in the communication data.
