Below shows the composition of data block which is transmitted in physical phase.
N
: Command byte counts (0 to 240)
Shows the number of parameters which are required by command.
axis
: Sets up the value of Pr5.31.(0 to 127)
command : Control command (0 to 15)
mode

Contents vary depending on the mode.
check sum : 2's complement of the total number of bytes, ranging from the top to the
end of the block

RTY: Maximum value of retry times. Transmission error occurs if the actual retry has exceeds this setup
value.
M/S: Switching of master and slave. When contention of ENQ has occurred, the module decides which
is to be given priority.
Priority is given to the transmitter which is set up as a master. (0: Slave mode, 1 : Master mode)
