See the figures behind the radix point, the fieldbus ratio value of the Max. output
frequency (P00.03) is 100. 100Hz timed by 100 is 10000 and the corresponding hex is
2710H.

7.3.8.3 Example of continous writing command10H
Example 1: make the inverter whose address is 01H run forward at 10Hz. Refer to the
instruction of 2000H and 0001. Set the address of "communication setting frequency" is
2001H and 10Hz corresponds to 03E8H. See the table below.
