Astraada DRV-24 frequency inverters Communication protocol
111
Example 2: set the Max. Output frequency of the inverter with the address of 03H as100Hz.
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.

7.5.3 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.
