88 - 104   

Communication protocol

 

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. 
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): 
 

 

 
Note: 

the blank in the above command is for illustration. The blank can not be added in the actual application 

unless the upper monitor can remove the blank by themselves.
