According to the number of decimals, the fieldbus scale of the "Max. output frequency" (P00.03) is
100. Multiply 100 Hz by 100. The value 10000 is obtained, and it is 2710H in the hexadecimal form.
The command transmitted by the master is as follows:

purposes. In practical applications, no space is required in the commands.
9.4.8.3 Examples of continuously write 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.
