15. COMMUNICATION FUNCTIONS

15.5 Error codes

Error codes are used in the following cases and an error code of single-code length is transmitted.

On receipt of data from the master station, the slave station sends the error code corresponding to that data to the master station.

The error code sent in upper case indicates that the servo is normal and the one in lower case indicates that an alarm occurred.
