A.7 Communication error processing
Inverter receiving data packet detection error, it finds reading&writing parameter address or
parameter value invalid, so reply to the host with communication error response packet.
Communication error response packet (host command code+80H) as command code, with 1 byte
error code.
Format for communication error response packet as follows:
ADR 01H
CMD 83H/86H
Communication error code 01H~06H (for details, please check below table)
Low byte of CRC checksum Obtain by calculating
High byte of CRC checksum Obtain by calculating
Meaning for each communication error code value as follows:
Communication error code value Communication error type Priority
0x01 CRC checksum error 1
0x02 Command code illega 2
0x03 Register address visited illegal 3
0x04 Value to write register illegal 4
