Communication Protocol 123 - 144
If the response message is as below:
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.
RTU mode:
The command sent by the master:
If the operation is successful, the response may be as below (the same with the command sent by the
master):
ASCII mode:
The command sent to the inverter:
If the response message is as below:
9.6.3 Example of continous writing command 10H
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.
