Default
Modify
setting and the speed of acceleration (ACC)
and deceleration (DEC).
Setting range: P00.04–400.00Hz
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:

If the operation is successful, the following response is returned (same as the command
transmitted by the master):

7.5.3 Examples of continuously write command 10H
Example 1: Set the VFD whose address is 01H to be forward running at the frequency of 10Hz.
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.
