10.4.8.3 Example of continuously writing command 10H
Example 1: Set the VFD whose address is 01H to be forward running at the frequency of 10 Hz. Refer
to the table of other function parameters, 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. 10 Hz is 03E8H in the hexadecimal form.
