6.3.7.3 Examples of continuously write command 10H
Example 1: Set the VFD whose address is 01H to be forward running at the frequency of 10Hz. According to the table of
other Modbus function addresses, the address of "Communication-based control command" is 2000H, 0001H indicates
forward running, and the address of "Communication-based value setting" is 2001H, as shown in the following figure.
10Hz is 03E8H in the hexadecimal form.
