L200 Inverter

Appendix B

When sending a query (excluding a broadcasting query) to an inverter, the master always 
requests a response from the inverter. Usually, the inverter returns a response according 
to the query. However, when finding an error in the query, the inverter returns an excep-
tion response. The exception response consists of the fields shown below.

The content of each field is explained below. The function code of the exception 
response is the sum of the function code of the query and 80h. The exception code 
indicates the factor of the exception response.
