8.2.4.2 Command code 10H
Function: to read n words (n ≥ 2)
Example: If the command is to write 300 (0000012CH) to the address 03F2H of the servo drive with
the slave-node address 01H, the command frame structure is as follows:
Write MSB of data address
Write LSB of data address
MSB of data count (in word)
LSB of data count (in word)
Byte count
MSB of word 1 in data content
LSB of word 1 in data content
MSB of word 2 in data content
LSB of word 2 in data content
