9.4.8.3 Continuously write command 10H examples
Example 1: Set the inverter 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.
