10.4.2 Command code: 06H
06H (correspond to binary 0000 0110), write one word(Word)
The command means that the master write data to the inverter and one command can write
one data other than multiple dates. The effect is to change the working mode of the inverter.
For example, write 5000 (1388H) to 0004H from the inverter with the address of 02H, the
frame structure is as below:
RTU master command message (from the master to the inverter)
