The command byte is divided into upper and lower nibbles: the lower nibble is the command value; the
upper nibble is the number of additional data bytes, which will follow the command byte. The checksum
byte is 8-bit sum of the address byte, the command byte, and the data bytes. The number of data bytes
depends on the particular command chosen. After a command is issued, the corresponding drive will send
back a status packet consisting of:
Status byte
0-23 optional bytes of status data
Checksum byte
Communication interface
The status byte contains basic status information about the Drive, including a checksum error flag for the
command just received. The optional data bytes may include data such as the position, velocity, etc. and
are programmable by the host. The checksum byte is the 8-bit sum of the status byte and the additional
status data bytes.
The transmission of all 16-bit and 32-bit data is always with the least significant byte first.
