Communications Error Codes
The Inverter will detect a communications error if normal communications fail or a mes-
sage data error occurs.

the MSB set to 1, error code, and CRC-16 check block when the communications error is
detected.
When the Master receives an error code, refer to the following table for troubleshooting
and remedying the error.
